Changelog

6.19.0

April 5th 2024

UPDATES

  • Fixed an issue with the Surface component using a Selection as its datasource.

6.18.0

April 4th 2024

UPDATES

  • Fixed an issue with the type of a new port not being set correctly on the Port object via the addNewPort method on a Toolkit instance.

  • Fixed an issue whereby dragging multiple nodes causes miniview to fail to update properly in activeTracking mode

  • Fixed issue with Firefox wheel direction being opposite to other browsers

  • Updates to the endpoints and anchor docs

  • Introduced https://apidocs.jsplumbtoolkit.com, a new and improved home for our api documentation.

6.17.0

March 26th 2024

UPDATES

Miniview

  • The miniview now actively tracks when a node/group is being dragged in the related Surface. This behaviour can be switched off via the activeTracking flag in the miniview options.

  • Using wheel zoom or pinch zoom on the miniview now results in the related Surface zooming in on the point that maps to where the user is zooming on the miniview. Prior to 6.17.0 the related surface would be zoomed in on the last place zoomed on the surface itself.

  • Nodes/groups can be clicked in a miniview and the related Surface will pan to center the clicked node/group. This behaviour is switched on by default and can be switched off via the clickToCenter flag in the miniview options.

6.16.0

March 25th 2024

UPDATES

  • We've made a major improvement to orthogonal connector path editing, for which a picture is definitely worth a thousand words, so we'd recommend checking out either the Flowchart builder starter app, the documentation about orthogonal connector path editing, or the 6.16.0 release announcement. In a nutshell, it's now far harder for a user to inadvertently get the UI into the situation that a connector doubles back onto itself underneath a vertex, which makes for a more intuitive experience.

  • It's no longer necessary to declare the BaseNodeComponent or BaseGroupComponent mixin when using the Vue2 or Vue3 integration packages. These mixins are automatically added by JsPlumb if not specified in your component.

MISCELLANEOUS

  • Several events that were previously fired by the UI layer but not consumed by the Surface have been removed, as have their associated constants.
  • The UI rendering layer's "lists" package has been removed. This package was part of the Community edition and was not exposed via the Toolkit API.

6.15.0

February 18th 2024

UPDATES

  • When a new node is dropped onto some existing node via the drop manager, the onVertexAdded callback on SurfaceDropManager now passes back information about the vertex on which the new node was dropped.

  • Support for the onVertexAdded callback was added to ShapeLibraryPalette

  • Added new panWithMetaKey option to Surface render params.

6.14.0

February 16th 2024

UPDATES

  • Added support for optional cornerRadius to Segmented connector.
  • Fixed issue with path editor incorrectly trying to edit an edge that had been aborted by a beforeStart interceptor.

2.50.0

February 2nd 2024

  • This is a re-release of the last version in the 2.x branch (2.4.6), upgraded with support for Angular 16+.

6.13.0

January 31st 2024

UPDATES

  • Added a fix for a very specific orthogonal geometry loading issue, involving nodes in a straight line that are close together.
  • Updated setPan method to fire a pan event.

6.12.0

December 28th 2023

UPDATES

  • Fixed an issue with the surface's destroy method when a background image was in use.
  • added autoSaveType option to Surface, allowing you to specify which exporter to use when auto save is switched on
  • added optional type to AutoSave constructor, allowing you to specify which exporter to use when saving.

BREAKING

  • The exportData method no longer writes a ports section into the output. You can use legacy-json as the type when exporting data if you still need this, but in 7.x that will be removed.

IN OTHER NEWS

We're continuing our internal refactoring to remove duplicated and unnecessary code, with this release seeing several key methods abstracted and pushed down to the UI core.

6.11.0

December 20th 2023

NEW FUNCTIONALITY

  • Added support for exporting a Path or Selection (including the current selection for some Toolkit instance) to an SVG/PNG/JPG.

  • New layout GridLayout added. This layout places elements into a grid, optionally with a fixed number of rows or columns, and with the ability to align items to the left/top/bottom/right of each cell.

  • Group size preview pane shown when dragging an element inside an elastic group is now displayed on ancestors of the group if they are also elastic.

  • Added the ability to run an ad-hoc layout on a group, via the adHocGroupLayout method on a surface.

  • Support for setting node/group sizes from the model has been added, including support for specifying default node/group sizes in the event that the vertex data does not contain size information. Read more about this in our docs - https://docs.jsplumbtoolkit.com/toolkit/6.x/lib/nodes-and-groups#setting-nodegroup-size

UPDATES

  • Internal updates to React integration to improve performance and reduce code duplication.
  • Refactoring of various positioning methods to remove duplicated code
  • Improvements to group auto sizing when nested groups are expanded or collapsed.

BREAKING

  • React integration no longer supports setting asynchronous to false on the JsPlumbToolkitSurfaceComponent. Asynchronous is mandated.

6.10.0

December 10th 2023

In 6.10.0 we have given group rendering an overhaul, adding some nice new features and fixing a few minor issues with the existing features. We've also updated the code to play nicely with Svelte Kit SSR, and added a couple of useful features to the Surface.

NEW FUNCTIONALITY

  • New flag elastic available for group rendering. An elastic group shrinks and grows as the nodes/groups inside of it are dragged around.

  • Added new panFilter optional function to Surface options, allowing you to control at runtime whether or not panning should be enabled.

  • Added support for optional minSize parameter in group definitions in the view. This is of type Size.

  • Added support for optional padding parameter in group definitions in the view. When autoSize is set on a group, this padding will be set around the child nodes/groups of an auto sized group. Default value is 0.

  • Added support for optional allowShrinkFromOrigin flag on group definitions in the view. Implicitly true when autoShrink or autoSize is true, you can set this to default if you don't want your groups to be able to shrink from the left/top edge.

  • When dragging a child element from a group, the parent group is assigned a CSS class of .jtk-drag-original-group. You can attach a z-index rule for this class to ensure that nodes/groups you drag from a given group will appear on top of any target group.

  • Added setEnabled(boolean) method to the Snaplines plugin, allowing you to enable/disable the plugin at runtime.

  • Added support for passing in styles to SVG exporter, for inclusion in a style element in the SVG export.

UPDATES

  • Improvements to orthogonal routing to handle vertical alignment in Hierarchy layout

  • Updates to the browser UI core code to fix a couple of issues that were causing the code to fail to load in SvelteKit SSR.

  • The behaviour of autoShrink and autoSize has been improved to support shrinking a group from its left/top edge where applicable. Previous versions of the Toolkit could only shrink a group from its right/bottom edges.

  • Fixed an issue with group auto size when an element is dragged into the negative axis. Previous versions of the Toolkit would size the group to fit the new content bounds but leave the dragged element hanging out of the group. In 6.10.0 the group is shifted to adjust for this.

  • Several improvements were made to the interaction between a Toolkit instance and its associated undo/redo manager, to ensure that no stray commands are tracked by the undo/redo manager during data load/append.

BREAKING

  • The maxSize option to group definitions is now a Size object, with a w and h property, instead of an array of [w,h].

  • autoSize switches on autoShrink by default now. Consider just using autoGrow if this is not what you want.

  • When autoSize or autoShrink is set, groups may now adjust their left/top edges to fit the content (taking into account any minSize set on a group). You can set allowShrinkFromOrigin:false to suppress this behaviour.

  • When dragging an element that is a child of a group, the original group is now assigned .jtk-drag-active and .jtk-drag-hover CSS classes, where in previous versions it was not. We think this provides a better experience for users but if you prefer the old behaviour you can use the fact that the .jtk-drag-original-group class is now added to the parent group to setup rules to mimic the old behaviour.

IN OTHER NEWS

A number of internal code changes have been made in 6.10.0 to reduce code duplication. The Toolkit edition, up until a few versions ago, used the Community edition as an external dependency, which meant that certain constructs and responsibilities were duplicated. The Community edition has now been ingested into the Toolkit edition's codebase and little by little we are refactoring to remove these duplicates.

6.9.2

November 30th 2023

UPDATES

  • Packaging updates

6.9.1

November 24th 2023

UPDATES

  • Updates to React integration to better support Next.js
  • Updated the wheel listener to check for existence of document before testing for available event (SSR fix for Next.js)

6.9.0

November 22nd 2023

BREAKING

  • The Community ingest code has been removed. The Community and Toolkit editions in fact diverged several versions back and this code was likely not working in many scenarios. No Toolkit licensees use(d) this code.

  • Constant TYPE_CONNECTOR_SEGMENTED was renamed to CONNECTOR_TYPE_SEGMENTED

NEW FUNCTIONALITY

  • Support for generating edge routing information was added to the Hierarchy layout.
  • New plugin edgeRouting added. This plugin can ingest the edge routing information generated by a Hierarchy layout and adjust the routes of the edges in the UI, with support for separated orthogonal, bus orthogonal and direct line modes.
  • Support for the number input type was added to Dialogs
  • Support for the number input type was added to Inspectors

UPDATES

  • A fix was added to the Orthogonal connector's geometry import routine to catch an unexpected formatting error in the geometry.

6.8.2

November 9th 2023

NEW FUNCTIONALITY

  • Added support for defaultSize to node/group definitions. Allows you to fix the size for a given vertex type without requiring that the values be in the vertex's backing data.

  • Added support for nodeSize to UI defaults. This is a fallback for the case that your vertices need to be rendered with a specific width/height but the values are not necessarily going to be available in the backing data.

UPDATES

  • Fixed an issue with loading hierarchical-json over ajax - the content type was not correctly recognised and the data not parsed to JSON.

6.8.1

November 8th 2023

NEW FUNCTIONALITY

  • The ImageExporter class now supports an optional width or height for the exported image. Width takes precedence; the aspect ratio of the underlying content is always maintained.
  • Added optional onShow and onDimensionsChanged callbacks to ImageExporterUI.
  • Added the ability to ImageExporterUI to specify a list of sizes from which the user should be able to choose for their exported image.

6.8.0

November 4th 2023

NEW FUNCTIONALITY

  • Shape libraries now support defs - snippets of SVG that you can declare in the header of a shape set and reference in the individual templates. This reduces bloat and increases readability.

UPDATES

  • Improvements to the hierarchy layout's crossing stage to reduce the chance of overlapping edges
  • Improvements to SVG/PNG/JPG export UI
  • Improvements to SVG export output: edges are drawn first in the SVG so that nodes will be placed on top in non-browser settings.

6.7.2

October 30th 2023

UPDATES

  • Fixed an issue writing attributes to the xlink namespace in the vanilla template engine
  • Updated template parsing code to better handle extraneous whitespace.
  • Improvements to the preview view of the svg/png/jpg export code
  • Updated jsdocs for Vue 2 and Vue 3 integration packages
  • Added the ability to register a Surface on Vue 2 and Vue 3 manually - allowing you to use vanilla templating inside of a Vue app.

BREAKING

  • The order of arguments in the fixElement method has been switched from (el:Element, constraints:FixedElementConstraints, pos:PointXY) to (el:Element, pos:PointXY, constraints?:FixedElementConstraints). This better reflects the fact that constraints is an optional argument whereas pos is not.

6.7.1

October 25th 2023

UPDATES

  • Added support for initialSet parameter to the jtk-shape-palette component in the Angular integration.
  • Added support for initialSet parameter to the ShapeLibraryPalette component in the React integration.
  • Added support for initialSet parameter to the ShapeLibraryPlugin component in the Vue 2 integration.
  • Added support for initialSet parameter to the ShapeLibraryPlugin component in the Vue 3 integration.
  • Fixed issue with extracting value from SELECT on change in inspectors

6.7.0

October 19th 2023

NEW FUNCTIONALITY

  • New plugin Snaplines added. This provides your users with visual cues about the alignment of the elements in their UI.

  • Added a new shape set - basic shapes. This includes things like rectangles, ellipses, triangles, hexagons, octagons etc. We've added these to the Flowchart Builder starter app.

  • The surface component now supports an editablePaths flag, which, if set, sets up a path editor internally and allows you to call methods on the Surface directly to edit paths. It also ensures the path editors are included and will not slip through any tree shaker.

  • The drawing tools plugin now supports a constrainGroups flag, which, if set, will prevent the group from being resized to such a point that any of its child members are out of the viewport.

UPDATES

  • Fixed an issue with the grid background plugin where if any elements were positioned in the negative x or y axis the surface's clamping was computed incorrectly.

  • The drawing tools plugin will not now resize a collapsed group.

  • Improvements to API docs to remove a bunch of internal members.

  • Some CSS classes were added for basic styling of a shape library palette.

  • The shape library palette takes an optional initialSet parameter, allow you to specify an initial shape set to show and hide the others.

  • When a single shape set is shown, the shape library palette doesnt show its title

6.6.5

October 13th 2023

NEW FUNCTIONALITY

  • Added ElementDragger helper class - use this to configure any DOM element that is not part of your canvas to be draggable.
  • Added a new starter application - "Neighbourhood Views" - showing how you can use the Toolkit to render dynamically changing selections.

UPDATES

  • Fixed an issue in the Svelte integration whereby a missing component mapping could cause an error.
  • Fixed an issue with the centerOn method that was introduced by some refactoring in 6.6.4.
  • Added support for getRootNode() method on HierarchyLayout, allowing you to dynamically specify the root node each time the layout is run.
  • Improvements to Hierarchy layout placement when the dataset consists of a set of unconnected nodes

6.6.4

October 10th 2023

UPDATES

  • Added cacheTemplates:boolean flag to VanillaInspector. In some cases you'll want to regenerate an inspector template based upon dynamic values in the object being inspected, and for that you'll want to turn the template cache off.

  • Improved the way the canvas animates in response to changes in zoom and position. Now uses requestAnimationFrame for that full 60 FPS experience.

  • Added new 'Orgchart' starter application

6.6.3

October 4th 2023

UPDATES

  • Fixed an issue in the inspector whereby edits were lost when the Toolkit's current selection is cleared
  • Updated inspector to commit values after enter keypress on text inputs and text areas
  • Fixed a sizing issue with the background element of an SVG text overlay
  • Added support for onMaybeClear to the React controls component - allows an alternative to the window alert confirming dataset clear.

6.6.2

September 26th 2023

UPDATES

  • Added attributes to Custom overlays to support auto rotation. See the overlay docs for more information.

6.6.1

September 20th 2023

UPDATES

  • Added dominant-baseline:middle to labels rendered by shape libraries.

6.6.0

September 20th 2023

NEW FUNCTIONALITY

  • Support for SVG/PNG/JPG export for Surfaces that are using a ShapeLibrary was added.

  • The Angular service was augmented with new methods to support exporting to SVG/PNG/JPG

  • The ShapeLibrary component now supports rendering labels to shapes as part of their SVG element.

  • A new flag useHTMLElement is supported on Label overlays. Setting to false will result in the Toolkit using an SVG text element for the label overlay, rather than an HTML element.

  • A new flag useHTMLLabel was added to edge definitions, which you can use to override the new default behaviour of using an SVG text element for the default label.

BREAKING

  • The ShapeLibraryPalette no longer registers a jtk-shape tag on the associated Surface. Instead, the shape library needs to be passed in the render options to the Surface. See shape library documentation for details.

  • When you specify a label in an edge type, the Toolkit now creates an SVG text element for it, rather than an HTML element.

  • By default, hover events are now switched off in the UI layer. We expect this change to affect almost nobody at all. For a full discussion of the reasoning behind this, see the documentation on rendering at https://docs.jsplumbtoolkit.com/toolkit/6.x/lib/rendering. You can switch them back on by setting hoverEvents:true in your render params.

UPDATES

  • Fixed an issue with the lasso plugin that would cause it to fail on devices with touch + pointer input methods.
  • Fixed an issue whereby a cssClass defined on an edge mapping would not be applied to a newly created edge.

6.5.0

September 3rd 2023

NEW FUNCTIONALITY

  • A new connector type - Segmented - has been added. This connector consists of a set of straight line segments, and can be smoothed to a set of bezier curves.

  • A path editor for the Segmented connector type has been added.

UPDATES

  • Orthogonal connector editor automatically trims any supplied geometry after load, to ensure the internal geometry is in a format that the editor can manage.

  • Fixed an issue whereby path tracing between groups was failing.

  • The jsplumbtoolkit-connector-editors.css stylesheet was refactored slightly, to introduce common base classes for edge handles, and to use CSS variables.

  • The controls component now detects the existence - or otherwise - of a Lasso plugin on the associated Surface, and does not draw the mode change buttons if the Lasso is not present.

6.4.1

August 30th 2023

UPDATES

  • Further fix for Orthogonal path recomputation when stubs are not active.
  • Fix for group load issue: when a group loaded via the load method declared it was a member of some group which was not part of the data load but was in the Toolkit, it could not be loaded.

6.4.0

August 30th 2023

BREAKING

  • The alwaysRespectStubs flag defaults to true in the Orthogonal connector now.

UPDATES

  • Fix for an issue with recomputing Orthogonal path when stubs are not active.

6.3.0

August 4th 2023

UPDATES

  • When dragging an edge, the class jtk-surface-edge-dragging is added to the surface container.
  • For licensees who hold a team license - 5 seats or more - the ES6 source code is now available as a separate download.
  • EdgePathEditor was updated so that it no longer requires anchorPositions to be passed in if these are defined on a node/port/group definition in the view.

BREAKING

  • Version 2.x is no longer supported.

6.2.15

July 29th 2023

Further packaging updates. No code changes.

6.2.14

July 28th 2023

UPDATES

  • Fixed an issue whereby overlays that had been programmatically added to an edge (eg via the edge path editor) would be hidden upon edge update.
  • Improvements to packaging for evaluators to include types directory.

6.2.13

July 27th 2023

This release contains only internal updates to packaging. No code changes.

6.2.12

July 25th 2023

UPDATES

  • EdgePathEditor was updated to ignore edges loaded programmatically via the load method of the Toolkit. Edges loaded in this way already have geometry set and do not need to be updated.
  • Updates to Orthogonal connector to better handle node drag when initial path consists of a single horizontal or vertical segment.

6.2.11

July 19th 2023

BREAKING

  • The EdgePathEditor now defaults to true for the activeMode option. Although this is a breaking change it in fact brings the behaviour of the path editor more into line with what people expect: any new edge that is dragged automatically has a geometry attached to it, meaning if the dataset is exported without the edge being edited it will be reinstated with the same path.

UPDATES

  • A fix was added to correct an issue introduced by the change to the EdgePathEditor in 6.2.10. Geometry is now correctly written to an edge that has been dragged by the user when activeMode is true (which, as mentioned above, is now the default).

6.2.10

July 14th 2023

BREAKING

  • The katavorio-drag-no-select class is no longer added to the document body during element drag. There was no corresponding style declared in the default CSS stylesheet, so it is unlikely this class is being used by anyone.

UPDATES

  • Inspectors were updated to ensure they close themselves if the object they are currently displaying is deleted from the dataset.
  • An update was made to the EdgePathEditor to ensure that edge geometry is written correctly when activeMode is set to true.
  • In the base port component and the miniview component in the React integration, the overridden props and state class members were removed, as their presence was causing React to report a warning in the console.

6.2.9

June 28th 2023

UPDATES

  • Added support for addHelperClasses flag in Surface dragOptions. Defaults to true. When false, prevents the Surface from adding classes to the canvas to indicate an element is being dragged.

6.2.8

June 23rd 2023

UPDATES

  • Update generic type parameter bounds in ShapeLibraryPalette and Angular service shape library methods to satisfy strict TS builds.

6.2.7

June 23rd 2023

UPDATES

  • Update ShapeLibraryImpl generic type parameter bounds to satisfy strict TS builds.

6.2.6

June 21st 2023

UPDATES

  • update controls component to set state attributes on its rendered root element rather than the container in which it resides.

6.2.5

June 20th 2023

UPDATES

  • added jsplumbtoolkit-edge-type-picker.css stylesheet
  • add visibility:visible !important to edge path delete button overlay.

6.2.4

June 20th 2023

GENERAL

  • Updated EdgeTypePicker to repaint itself after a window resize event, to ensure edges are painted in the right place.
  • added ControlsComponent, a component from our demonstration apps that might be useful for others.
  • fixed issue in connector editor package where re-editing an edge that it was already editing would cause any extra overlays to be removed.
  • fixed issue in bezier connector editor where control points were being dragged at twice the rate the mouse was moving.

BREAKING

  • The jsplumbtoolkit-connector-editors-orthogonal.css and jsplumbtoolkit-connector-editors-bezier.css stylesheets were removed. The styles contained in both of those stylesheets exist in the jsplumbtoolkit-connector-editors.css stylesheet.

6.2.3

June 17th 2023

GENERAL

  • Update shape library palette to support configurable iconSize property.

6.2.2

June 16th 2023

GENERAL

  • Updates to custom tag registration to allow shape libraries to be used without a ShapeLibraryPalette.

6.2.1

June 16th 2023

GENERAL

  • The default number of iterations for the ForceDirected layout was increased from 5 to 15.
  • Updated JS doc for ShapeLibraryImpl
  • Updated custom tag renderer to remove expectation that a rendered and/or updated function would always be provided.

6.2.0

June 16th 2023

GENERAL

  • Improvements to support for tree shaking

  • The drop manager now adds a jtk-drag-drop-current class to the element currently being dragged

  • Several enhancements were made to the drawing tools plugin - placement of new nodes is now correct when the surface has a zoom level of anything other than 1, and if the surface has a grid applied this is also honoured.

  • The default styles for edge path editors no longer contain a rule for painting the edge path to a specific color. For applications in which the user has control over the edge color this is a better experience. For users who wish to add this functionality that can be done via the inclusion of a CSS rule - see documentation on CSS.

  • Updates to the default template engine to ensure that elements written by custom tags are correctly updated when their vertex is updated.

  • The default number of iterations for the ForceDirected layout was reduced from 50 to 5.

NEW FUNCTIONALITY

  • A new module browser-ui-shape-library was added. This package contains various helper components for working with SVG shapes, for applications such as flowchart builders, entity relationship diagrams, etc. For a full discussion of the capabilities of this module, see https://docs.jsplumbtoolkit.com/toolkit/6.x/lib/shape-libraries.

  • Support for the browser-ui-shape-library module was added to the Angular, Vue2, Vue3, React and Svelte integrations.

  • A new module browser-ui-inspector was added. This contains some support code for implementing form-based object inspectors that integrate tightly with a Surface/Toolkit instance. For a full discussion of the capabilities of this module, see https://docs.jsplumbtoolkit.com/toolkit/6.x/lib/inspectors.

  • Support for the browser-ui-inspector module was added to the Angular, Vue2, Vue and React integrations.

  • Added the canvasDropFilter to SurfaceDropManager. The parent class DropManager already supported this but it was not exposed on the SurfaceDropManager prior to 6.2.0.

  • An optional dragSize parameter can be supplied to the drop manager, to set the size of nodes/groups that are being dragged.

  • Support for a modelEvents object has been added to the Surface's constructor. Instead of having to register model events after the fact you can now supply them with your render parameters.

  • The concept of 'mode' was added to selections: you can specify that a given selection may only contain one type of object (eg nodes, groups or edges), or that it can contain a mix. For more information see the documentation at https://docs.jsplumbtoolkit.com/toolkit/6.x/lib/selections#selection-mode

  • Edge editors now snap anchor placeholders to the closest anchor when the user is relocating an anchor. Previously the placeholder would not be snapped until the use released the mouse button. The previous behaviour can be reinstated by setting snapToAnchors:false in the options you pass to the startEditing method.

  • When dragging a new edge, the Surface element will now honour a type specifier returned from a beforeStartConnect interceptor. In previous versions the type would only be honoured once a new connection had been established. For more information see https://docs.jsplumbtoolkit.com/toolkit/6.x/lib/interceptors#beforestartconnect.

  • Support for 'fragments' was added to custom tags in the default template engine. This is more of an internal feature, but could be leveraged by advanced users of the Toolkit. See documentation on templating for further information.

  • Label overlays now have a jtk-label-overlay class added to their element.

  • The default CSS stylesheet was updated with a visibility:hidden rule for .jtk-label-overlay:empty. For label overlays on which the label's value is currently an empty string, this will hide the overlay.

  • The CSS for the "controls" component that we ship along with each of the library integrations was copied out from jsplumbtoolkit-demo-support.css and into jsplumbtoolkit-controls.css, and the various selectors were updated to be more specific.

BREAKING

  • Simple edge styles are now enabled by default on the Surface component. They can be switched off via simpleEdgeStyles:false in your render options.

  • The PanZoom widget, which is used internally by the Surface, has been decoupled from the Surface and its constructor parameters have been updated. This will only be an issue for licensees who use the PanZoom stand alone.

  • The jsplumbtoolkit.css defaults stylesheet was updated to use CSS variables. This is only really listed as a 'breaking' change out of an excess of caution. There are very few browsers in use nowadays that do not support CSS variables.

  • The important modifier was removed from the default style for the .jtk-surface-selected-element class, which is applied to vertices that are part of the Toolkit's current selection.

BUGFIXES

  • Fixed issue with anchor placeholder not being centered correctly when editing an edge.
  • Fixed issue with Hierarchy layout where certain combinations of unattached roots and multiple parents could cause the layout to fail, due to a cache not being cleared.

6.1.1

May 12th 2023

  • Updates to build for evaluators

6.1.0

May 11th 2023

  • Angular integration is now built as an Ivy lib (necessary in order to support Angular 16)

  • Hierarchy layout has been updated to support centering child nodes with respect to their parent, mimicking the behaviour of the Hierarchical layout.

  • Hierarchical layout is now marked deprecated. Use Hierarchy instead.

BREAKING

  • Internally, the Hierarchical layout no longer uses a getChildEdges helper function, but rather a getChildVertices function. This change will only affect those who are using the Hierarchical layout with a custom edge finder. It has no impact on the functionality of the layout itself.

6.0.5

April 18th 2023

  • Internal code reorganisation. No functional change.

6.0.4

April 14th 2023

  • Fixed an issue in the Community edition where endpoints to set to invisible would be repainted under certain revalidation scenarios.

6.0.3

April 5th 2023

  • Packaging updates for evaluation builds

6.0.2

April 4th 2023

  • Fixed issue with the packaging of the Vue integration.

6.0.1

April 4th 2023

  • Added bezier and statemachine connectors to @jsplumbtoolkit/browser-ui

6.0.0

April 4th 2023

BREAKING

  • Support for the original templates syntax (where variable interpolations are of the form ${...}) has been dropped, throughout the Vanilla toolkit and the dialogs. The code from the previous templates-2, dialogs-2 and browser-ui-vanilla-2 packages has been retained in the @jsplumbtoolkit/browser-ui package, and the code from templates, dialogs and browser-ui-vanilla has been dropped.

  • The Spring layout has been removed. Use ForceDirected instead.

In order to support the single @jsplumbtoolkit/browser-ui package, several factory methods were renamed/removed:

  • newInstance(surface) in previous @jsplumbtoolkit/browser-ui-anim removed. Use new SurfaceAnimator(surface) instead.

  • createManager in previous @jsplumbtoolkit/drop package is now exposed as createDropManager in @jsplumbtoolkit/browser-ui

  • createSurfaceManager in previous @jsplumbtoolkit/drop package is now exposed as createSurfaceDropManager in @jsplumbtoolkit/browser-ui

  • newInstance(surface:Surface, options?:ConnectorEditorOptions) from previous @jsplumbtoolkit/connector-editors method removed - use new EdgePathEditor(surface:Surface, options?:ConnectorEditorOptions) instead.

  • initialize() method from previous @jsplumbtoolkit/connector-editors-bezier is now exposed as initializeBezierConnectorEditors() on @jsplumbtoolkit/browser-ui.

  • initialize() method from previous @jsplumbtoolkit/connector-editors-orthogonal is now exposed as initializeOrthogonalConnectorEditors() on @jsplumbtoolkit/browser-ui.

  • newInstance(params:DialogsOptions) from the previous @jsplumbtoolkit/dialogs-2 package has been removed. To instantiate Toolkit dialogs now, use new Dialogs(params).

  • The HORIZONTAL and VERTICAL axis identifiers from the HierarchicalLayout have been moved into the enum HierarchicalLayoutOrientations.

  • The code from the related -drop package for each library integration (@jsplumbtoolkit/browser-ui-angular-drop etc) has now been pulled into the library integration's main package

5.13.7

March 28th 2023

  • Added support for injecting props into components in the Vue2/Vue3 integration packages.

5.13.6

March 21st 2023

  • Update to the fix applied in 5.13.5

5.13.5

March 18th 2023

  • Fixed issue with endpoint cleanup after aborted connection drag

  • Packaging updates for the layout-hierarchy package

5.13.2

December 7th 2022

  • Updated the lasso plugin to remove a global reference to document and instead use a lazy init method

5.13.1

November 28th 2022

BREAKING

  • The getAllEdges method of the Group class no longer returns edges connected to child vertices of the group, instead behaving exactly as getAllEdges does on Node.

UPDATES

  • Group now has the method getInternalEdges, which returns edges connected to child vertices of the group.
  • Improvements to the placement stage of the Hierarchy layout when invert is set to true.
  • added support for gatherUnattachedRoots flag on the Hierarchy layout - see documentation for discussion.

5.12.6

November 9th 2022

  • Internal refactoring of the templates-2 package

5.12.5

November 8th 2022

  • Updates to Angular overlay handling when an edge factory is in place.

  • Updated Angular overlay handler to ensure correct initialisation when new edges are dragged.

  • Added support for Angular's OnPush change detection to node/group/port/overlay components.

5.12.3

October 27th 2022

  • Updates to community edition event generator to directly invoke event handlers instead of attempting to bind a context to them. This change is transparent to Toolkit users.

  • Update to Angular overlay to prevent an exception being thrown when the overlay is present on a connection that is being dragged (meaning that there is not yet an associated edge in the model)

5.12.2

October 12th 2022

  • Improvements to Arrow overlay rendering

5.12.1

October 7th 2022

  • updates to packaging for the background plugin
  • addition of methods to hide/show backgrounds in the background plugin.
  • ensure copy/paste of edge correctly clones the edge's data

5.12.0

September 22nd 2022

BREAKING

  • In the generated grid background, showMinorLines is now showTickMarks, and minorLinesPerCell is now tickMarksPerCell.

UPDATES

  • Fix for an issue where the node:move:end event of the Surface did not contain all of the elements in the drag group.

  • Added support for dotted background in generated grid background, via gridType parameter ("dotted" or "lines"). Default is for lines.

  • Added dotRadius and tickDotRadius options to generated grid background, for use with GridTypes.dotted.

5.11.3

August 23rd 2022

  • Improvements to the documentation
  • Addition of setDraggable method to Surface, to set the draggable state of individual vertices.

5.11.2

August 18th 2022

  • Refactoring "simple edge styles" (color/line width) and edge labels. It is now possible to set an edge's color, line width, label (and its location) directly from the backing data for the edge.

5.11.1

August 18th 2022

  • Refactoring "simple edge styles" (color/line width)

5.11.0

August 17th 2022

UPDATES

  • Added code to catch and report circular references in view dependencies

  • Updated the view code to support multiple parents for a given node/group/edge/port definition

  • Added the concept of "simple edge styles" - automatically mapping a few key properties from each edge's backing data to the appearance of its corresponding connection in the UI. See documentation for more details.

  • Added the concept of a "property mapper", an alternative to the existing concept of edge styles, which maps specific property values in edge data to appearance. See documentation for more details.

5.10.9

August 16th 2022

BREAKING

  • the background plugin no longer assumes a type of "simple" by default: you have to always supply a type.

UPDATES

  • grid backgrounds now have defaults for fill/stroke written into the svg.
  • fixed issue with background plugin CSS stylesheet not being packaged.

5.10.8

August 16th 2022

  • Internal refactoring of background plugin to expose type members that can be used when configuring backgrounds in an ES6/TS development environment, to avoid the code being omitted through tree shaking.

5.10.7

August 15th 2022

  • Added support for generated grid backgrounds.

5.10.6

August 12th 2022

  • Fixed a couple of issues with edge placement in nested nodes/groups in the underlying community edition
  • Fixed an issue with the tiled background layer in the background plugin that was preventing it from rendering.
  • Reinstated the zoomToBackground method on the Surface widget
  • Added supportLegacyConnectorData flag to OrthogonalConnectorOptions. This offers a means for people migrating from 2.x to load datasets where there is path data for Orthogonal connectors in the 2.x format.

5.10.5

August 5th 2022

  • Update to the Angular component overlay code to fix an issue that occurred when an edge deletion was undone via undo().

5.10.4

August 3rd 2022

  • Added support to the Angular integration for using Angular components as overlays.

5.10.3

July 25th 2022

  • Minor internal refactoring. No functionality change.

5.10.2

July 22nd 2022

  • Minor internal refactoring. No functionality change.

5.10.1

July 21st 2022

UPDATES

  • Lasso plugin now updates the Toolkit's selection, rather than the Surface's drag selection, allowing the Surface to decide whether or not selected elements should be added to the drag selection.

5.10.0

July 21st 2022

UPDATES

  • The Surface widget no longer by default adds an element in the Toolkit's current selection to the underlying drag selection, instead maintaining a separate drag group for selected elements. What this means is that if you have a few elements selected and you drag one that is not selected, the selected elements will not also be dragged.

5.9.4

July 19th 2022

  • Upgraded to Typescript 4.x.

5.9.3

July 18th 2022

  • Packaging updates. No code change.

5.9.2

July 18th 2022

UPDATES

  • The surface widget now supports an instantiated Decorator in its decorators constructor parameter. This can be useful in situations where your code needs to work closely with the decorator's behaviour.

  • The args to the decorate method in a Decorator are now typed as DecorateParams (no changes, just the introduction of this type definition)

  • On a device that support touch events, the container element for a Surface is now assigned a jtk-surface-touch-device css class. The purpose of this is to allow you to style differently for touch devices, for instance by making visible elements that are only visible on hover on a device supporting pointer events.

  • On a device that supports pointer events, the container element for a Surface is now assigned a jtk-surface-pointer-device css class.

Note that

5.9.1

14 Juillet 2022

UPDATES

  • The constrainFunction that can be passed in the dragOptions to a Surface can now return null, indicating that for the given tick of the drag lifecycle there is no suitable place for the element and the element should not be moved from its previous position.

5.9.0

July 7th 2022

BREAKING

  • Backgrounds for the Surface element have been moved to a separate plugin - @jsplumbtoolkit/browser-ui-plugin-background

  • In the underlying Community edition, endpoints are no longer wrapped in a div element; instead their svg element is appended directly to the container. This isn't a major change but may require some minor CSS updates.

UPDATES

  • The jtk-endpoint element has been updated to no longer require that a data-jtk-port attribute be set. This enables you to declaratively register multiple endpoints that are mapped to the vertex itself in the data model rather than on logical ports on the vertex.

  • The onCanvasDrop callback of DropManager is now passed the size of the dropped element, and also the related mouse event.

  • You can now pass a constrainFunction to the Surface's dragOptions, which will be invoked whenever an element is dragged, allowing you to control where elements can be dragged.

  • SurfaceDropManager and DropManager have received a few improvements:

    • When dragging an element onto a Surface, the element being dragged will, by default, be scaled so that it appears at the same size as it will be when it is dropped (by matching the Surface's zoom). This behaviour can be switched off if desired.
    • When the underlying Surface has a constrainFunction that controls where its elements can be dragged, by default this function will also be used to control element dragging when the new element is in the Surface's viewport. This behaviour can be switched off if desired
    • You can pass an elementGenerator to SurfaceDropManager and DropManager, which is a function the Toolkit will use to get the element to drag, rather than cloning the drag element.

5.8.3

June 16th 2022

UPDATES

  • Updated React integration to fix an inconsistency in the way state was cleared after the data model is emptied via clear(). A warning was reported by React in the console.

5.8.2

June 15th 2022

UPDATES

  • fix for an issue in the node/group factories whereby a transaction could be left open if the user did not invoke either the continue or abort callback.

5.8.1

June 14th 2022

UPDATES

  • added support for 'id' attribute on SurfaceComponent in Svelte integration.
  • fixed an intermittent issue with updating templates in the templates-2 package: when an interpolated value was initially an empty string, the value could not be rewritten to boolean false.

5.8.0

June 9th 2022

BREAKING

  • Surface no longer fires EVENT_DATA_LOAD_END or EVENT_DATA_LOAD_START. It is unlikely these event subscriptions were in use, and they are a pass-through of the same event from the underlying Toolkit. If you want to listen for these events and you currently do so on the Surface, just bind to them on the Toolkit instead.
  • Drag groups have been extracted to a separate plugin

UPDATES

  • Surface now fires EVENT_RENDER_START and EVENT_RENDER_END at the beginning and end of the rendering of a set of data. EVENT_RENDER_END does not fire until every vertex in the dataset has been rendered (taking into account asynchronous rendering)
  • Updates to Vue 3 to better integrate with the asynchronous paint mechanism (in particular, when bulk loading and then running a layout)
  • Updates to React to better integrate with the asynchronous paint mechanism in React 18 (in particular, when bulk loading and then running a layout)
  • Added support for 'temmplate macros' to the @jsplumbtoolkit/templates-2 package. This brings templates-2 up to par with @jsplumbtoolkit/templates in terms of the complexity supported in injected values.

NEW PACKAGES

5.7.1

June 1st 2022

UPDATES

  • Update to ForceDirected layout to better support positioning newly added nodes

5.7.0

June 1st 2022

UPDATES

  • Reinstated support for directRender mode, which has not been properly supported in 5.x as of yet.

NEW PACKAGES

  • added new ForceDirected layout. This is a rewrite of the original Spring layout, with several improvements and a shorter run time. Users of the Spring layout are recommended to switch to this layout from 5.7.0 onwards. Available in the package @jsplumbtoolkit/layout-force-directed.

5.6.5

May 24th 2022

UPDATES

  • Updates to the Spring layout to ensure that running the spring layout over and over on a given dataset wont move nodes whose position has already been calculated (regardless of whether the position was initially in the model or calculated by the layout). This also applies when a new node is added to the dataset - existing nodes will not be moved.

5.6.4

May 21st 2022

UPDATES

  • Added the related ComponentRef to the arguments passed to thevertexEvent callback exposed by the Surface element in Angular integration.

5.6.3

May 20th 2022

UPDATES

  • Added optional toolkitParams as an Input to the Surface element in Angular integration.

5.6.2

May 6th 2022

UPDATES

  • Updated miniview to render existing dataset if attached after Surface has initially rendered.
  • Updated Surface to write positions to model after relayout and refresh if the storePositionsInModel flag was set to true

5.6.1

May 5th 2022

BREAKING

  • interceptors support removed from the Surface object. This was undocumented and unused, and interceptors are supported by the Toolkit.
  • panDistance moved from SurfaceOptions to the PanButtonsPluginOptions interface in the pan buttons plugin.

UPDATES

  • Updates to packaging for evaluation versions
  • Update to the React integration to fix a rendering issue in React 18 when calling load with JS data during a componentDidMount or useEffect initialiser.

5.6.0

May 3rd 2022

BREAKING

  • @jsplumbtoolkit/dialogs has now been renamed to @jsplumbtoolkit/dialogs-core, and is a base package for two new packages - @jsplumbtoolkit/dialogs and @jsplumbtoolkit/dialogs-2. If you use @jsplumbtoolkit/dialogs currently, then dialogs-core will be automatically imported; the only thing you need to be aware of is that the dialogs CSS file is now in dialogs-core, and not in dialogs, so any references you have to that will need to be updated. dialogs-2 is discussed below.

NEW PACKAGES

- `@jsplumbtoolkit/browser-ui-svelte`

This is an integration package to facilitate using the Toolkit with Svelte 3. Docs are here: https://docs.jsplumbtoolkit.com/toolkit/5.x/lib/svelte-integration

- `@jsplumbtoolkit/browser-ui-templates-2`

This is a rewrite of the default templates package (used by the `@jsplumbtoolkit/browser-ui-vanilla` renderer, not by the Angular/React/Vue integrations) that addresses, primarily, the fact that in certain sandboxed environments (such as Salesforce Lightning), "strict" mode is enforced and so `eval` and `with` - both of which the original templates package uses internally - are not available.

Currently this package is still considered experimental, not having had the same battle testing that the original template package has had, but it has other advantages too, such as using `{{...}}` instead of `${...}` for variable substitution, making it play more nicely with template literals, and the speed with which an update occurs is vastly improved over the original templates package. We encourage licensees to give this new package a try and we invite all feedback.

Detailed information on the differences between this package and the original templates package, as well as instructions for how to use the package with your existing code, can be found here on our docs site: https://docs.jsplumbtoolkit.com/toolkit/5.x/lib/templating-2

- `@jsplumbtoolkit/browser-ui-vanilla-2`

The vanilla Toolkit renderer, but using the new templates package instead of the original templates package. This is the renderer that we use now in all of our demonstration pages. For users of the current vanilla renderer we recommend switching to this package, as the original templates package (and therefore browser-ui-vanilla) is now in a lightweight maintenance mode, and is unlikely to be continued from v6.0.0 onwards.

- `@jsplumbtoolkit/dialogs-2`

This is a port of the original `dialogs` package that uses the `templates-2` package under the hood. Functionally there is no change from the original `dialogs` package, but the format of the templates you use with `dialogs-2` corresponds to the changes in `templates-2`.

UPDATES

  • Parameterised labels in views were updated to support {{value}} syntax as opposed to ${value}. This is to avoid confusion with JS string templates. The previous syntax is still supported for now but won't be as of v6.0.0.
  • The beforeConnect interceptor now takes an optional 4th argument which indicates whether the new edge is a result of user activity with a mouse/touch device, or if it is a programmatic edge addition.
  • Fixed an issue with the beforeDetach interceptor where in some cases the source and target parameters were empty (although they could be retrieved from the edge that is passed in to that interceptor anyway)

5.5.5

April 5th 2022

UPDATES

  • Fixed painting issue in orthogonal connector when a connection is established between endpoints on opposite faces of the same element.

5.5.4

April 5th 2022

UPDATES

  • Update Community edition's event manager module to not reference document in its root.

5.5.3

April 1st 2022

UPDATES

  • Optimising imports in both Toolkit and Community editions. No code change.

5.5.2

March 16th 2022

UPDATES

  • Fixed an issue preventing the magnetizer from running ad-hoc with the Spring layout.

5.5.1

March 12th 2022

NEW PACKAGES

  • New package @jsplumbtoolkit/layout-hierarchy added

This is a new layout that follows a slightly modified Sugiyama algorithm. Unlike the original Hierarchical layout, there is no assumption that any given node will have at most one parent, and consequently this layout typically performs much better on real world datasets than the Hierarchical layout. For more information - and future plans - see the Toolkit documentation.

5.5.0

March 10th 2022

BREAKING

  • Extracted "ui states" from the @jsplumbtoolkit/browser-ui package and put them into a plugin in the package @jsplumbtoolkit/browser-ui-plugin-ui-states. This shaves a bunch of Kb off the size of the browser-ui package. Details for how to migrate can be found in the documentation for UI States.

  • Several Surface render parameters related to how the mouse wheel is handled, which were marked deprecated in 5.3.0, have now been removed, or rather, moved and renamed:

    • wheelZoomMetaKey -> wheel:{ useMetaKey:... }
    • wheelReverse -> wheel:{ reverse:... }
    • wheelSensitivity -> wheel:{ sensitivity:... }
    • wheelFilter -> wheel:{ filter:... }
    • wheelPan -> wheel:{ pan:... }
    • enableWheelZoom -> wheel:{ zoom:... }

The default value for each of these parameters is still the same as in previous versions.

NEW PACKAGES

  • @jsplumbtoolkit/browser-ui-plugin-ui-states, as discussed above.

5.4.1

February 15th 2022

BREAKING

  • removed getPosition(..) method from Surface. Use getCoordinates(..) instead.
  • removed setVertexPosition(..) method from Surface. It was a duplicate of setPosition(..)

NEW PACKAGES

  • Added new @jsplumbtoolkit/copy-paste and @jsplumbtoolkit/browser-ui-copy-paste packages. See documentation for details.

UPDATES

  • Added activeMode optional constructor parameter for EdgePathEditor. When set, any new connection that has just been dragged will be marked "edited", meaning the geometry from the initial path is then fixed. This is a useful toggle if you're using an anchorPositionFinder in your code. See documentation for more details.

  • fixed possible geometry load issue with Orthogonal connectors in certain circumstances.

  • updated Orthogonal connector geometry load to allow usage with static (ie. not just Continuous or Dynamic) anchors.

5.4.0

February 10th 2022

BREAKING

  • Removed support for a templateRenderer declaration inside a node, group or port definition in a view. We know of no instances of this capability being used, and if it is needed, it can be handled inside a templateRenderer declared on the render params for a Surface.

UPDATES

  • Fix for potential recursive loop when elements in Balloon layout have connections to themselves.
  • Added support for anchorPositionFinder inside a node, group or port definition in a view. This provides a means for you to determine the anchor location for the source/target of some connection at drag time.
  • Added support for anchorPositionFinder to the connector editor package. Provides a means for you to determine where the source/target anchor of some connection can be dragged to when the connector is being edited.

5.3.11

February 6th 2022

UPDATES

  • Added checkValidity method to the dialogs package.
  • exposed extractValueFromElement method to get the value from a single element to the dialogs package.
  • Internal refactoring of the connector editors to standardise their drag behaviour with other parts of the Toolkit.

5.3.10

February 4th 2022

UPDATES

  • Added support to the dialogs extract and apply methods for a custom binder.

5.3.9

February 1st 2022

UPDATES

  • Refactored the dialogs internally to extract the DOM binding code for reuse in jsPlumb Toolkit Components.
  • Added optional autoCommit flag to the show method of Dialogs. By default this is true.

5.3.8

January 29th 2022

UPDATES

  • Updated the underlying community edition renderer to ensure that a user-provided anchor callback in a target selector is honoured.

5.3.7

January 27th 2022

UPDATES

  • Updated the drag handler in the underlying community edition renderer to ensure that a user-provided start callback cannot override the default drag start behaviour.

5.3.6

January 25th 2022

UPDATES

  • Updated the bindModelEvent and on methods of the Surface to handle multiple :not(..) selectors.
  • Fixed issue with wheelPan:true in pan/zoom widget not binding the wheel listener.
  • Updated setOverlaysVisible method of Surface to take an optional varargs list of overlay ids to operate on.

5.3.5

January 21st 2022

UPDATES

  • Fixed an issue whereby in some circumstances it was possible for a bindModelObject callback to be invoked without a model object supplied.

  • added setOverlaysVisible(Selection|Path|Edge|Array<Edge>, boolean) method to the Surface

  • updated the drop manager to support overridden left / top properties passed to the node factory callback.

  • added optional onVertexAdded callback to SurfaceDropManager, which will be invoked whenever a group/node has been dropped onto the canvas and added to the dataset.

5.3.4

January 12th 2022

UPDATES

  • Correction of the change in 5.3.3: jtk-source-hover and jtk-target-hover are applied to the elements involved in a connection, not the endpoints.

5.3.3

January 11th 2022

UPDATES

  • Reinstated the application of jtk-source-hover and jtk-target-hover classes to the source and target endpoint for some connection on which the mouse is hovering.

5.3.2

January 10th 2022

  • Fixed issue with endpoint hover: when hovering over an endpoint, endpoints at the other end of connections to that endpoint also hover.
  • Fixed intermittent issue with multiple definitions on an element that have Continuous anchor definitions with different faces.

5.3.1

December 20th 2021

UPDATES

  • added support for maxConnections in addTargetSelector method of Community edition.

5.3.0

December 15th 2021

UPDATES

  • Updated the exportData method to ensure that its output is insulated from the Toolkit's internal dataset
  • Updated to ensure the node:move:end event is fired after any necessary changes to the model.
  • Added toJson() to JsPlumbToolkit; you can now call JSON.stringify(someToolkitInstance) to get the same output you'd get from someToolkitInstance.exportData().

5.2.4

December 12th 2021

UPDATES

  • Fixed intermittent issue with not all edges being deleted when a group they are attached to is deleted.

5.2.3

December 7th 2021

UPDATES

  • Fixed issue with uniqueEndpoint on port definition not being honoured.

5.2.2

December 6th 2021

UPDATES

  • updated the tracePath method in @jsplumbtoolkit/browser-ui-anim to set a .jtk-animate-source class on the path source vertex and a .jtk-animate-target class on the path target vertex for the duration of the trace.

  • fixed issue with maxConnections on port definition not being honoured.

5.2.1

November 30th 2021

UPDATES

  • Added fix for a node/edge asynchronous rendering issue when using the data prop of the Vue3 surface.

5.2.0

November 28th 2021

UPDATES

  • Replaced Dictionary<T> throughout the codebase with Record<string, T>. Dictionary had been marked deprecated for a few versions.

  • Community edition updated to better handle anchor orientations with dynamic anchors.

5.1.2

November 26th 2021

UPDATES

  • Fixed issue with parsing of nested groups via the load function.

5.1.1

November 26th 2021

UPDATES

  • Small change to event registration for connection drag handlers. No functional change but this reduces any lag at the start of a drag.

5.1.0

November 25th 2021

UPDATES

  • compound is no longer an available flag on the undo/redo parameters passed to a Toolkit constructor. If an edge is deleted as part of a call to removeNode or removeGroup, its deletion is automatically wrapped in a transaction by the Toolkit. But if an edge is deleted independently of a vertex then it has its own undo/redo stack entry.

  • wheelFilter was reinstated.

5.0.0

October 29th 2021

5.x is a rewrite to Typescript, with a focus on modules. This work presented a rare opportunity to perform refactoring for clarity and performance purposes. As the list of changes grew, it was decided to move them out of the changelog and into a dedicated migration guide document.

In 5.x, the Toolkit and Community edition versions will be kept in step: Toolkit: version 5.a.b of the Toolkit always corresponds to version 5.a.b of the Community edition.

2.1.3

11th June 2020

UPDATES

  • Minor refactoring to the internals of the Surface when a node is removed. In certain rare circumstances there could be endpoints that did not get cleaned up.

2.1.2

30th May 2020

UPDATES

  • In the Angular integration, jsPlumbDragDropComponent and jsPlumbSurfaceDropComponent refactored to be Directive rather than Component. This makes no difference to their operation, but it is more correct conceptually, and also allows you to extend them with your own Directives.

  • updated types: added elementFilter as optional to MiniviewOptions

  • added support for [elementFilter] on jsPlumbMiniview Angular component

  • added redraw method to jsPlumbMiniview Angular component

2.1.1

19th May 2020

UPDATES

  • added onDemand flag and edit method to drawing tools, to enable on-demand attachment of drawing tools instead of via Toolkit selection.
  • fixed issue in which it was not possible to lasso nodes that were previously in a group that was deleted.
  • ensure groups on which nodes are dropped have their layout re-run
  • fixed a race condition in the auto save mechanism that could cause incorrect values for nodes previously belonging to a group that has been removed.

2.1.0

10th May 2020

BREAKING

For the time being, the original version of the Vue integration is available in jsplumbtoolkit-vue2-runtime.tgz, but this will at some point be removed.

UPDATES

  • Fixed issue in which a node removed from a group did not have its position updated in the model (when storePositionsInModel is set to true)
  • Added jsplumbtoolkit-testing package. This provides a set of helper methods for you to use when testing a UI that includes the jsPlumb Toolkit.

2.0.6

1st May 2020

UPDATES

  • upgrade to Community edition 2.13.2
  • group:addMember and group:removeMember added to the list of events that instigate an auto save.
  • added context as an argument to edge factory. This provides all of the context information for the edge being created - source, target, etc. For more information search "edge factory" on docs.jsplumbtoolkit.com.
  • performance enhancements for large numbers of nodes/edges

2.0.5

27th April 2020

BREAKING

  • The internal representation of templateRenderer now expects it to be an object containing a render method and a cleanup method. If you have a custom template renderer then you need to update it to satisfy this contract. The render method should just be whatever your current templateRenderer function is. cleanup is expected to perform any deregistration that is required, and also to remove the rendered element from the DOM.

UPDATES

  • Fixed issue with miniview ignoring the wheelReverse setting of its associated surface.
  • Update Angular, React and Vue integrations to ensure components are destroyed when the Toolkit is cleared (via the clear() method).
  • added a clear button to all of the Flowchart demonstrations.
  • Undo/redo manager clears its history when the related Toolkit is cleared.

2.0.4

14th April 2020

UPDATES

  • Updated all Angular demonstrations to Angular 9 (with aot)

  • Minor updates to internal packaging of Toolkit code

  • Updates to the database visualizer demonstrations:

    • separated out id and name members of columns. Previously, the id of the column was also its name, which was mostly just a conceptual problem, but for the React database visualizer it meant the inclusion of some extra code to generate a unique 'key' for each column.
    • introduced a 'contacts' table, linked to Author, Publisher
    • set detachable:false on edge definition so the user has to use the X button to delete a relationship
  • Added support in the Undo/redo manager for adding node to/removing node from Groups.

  • setPosition method of Surface now stores new position in model if configured to do so

  • Added support in undo/redo for group drag

  • fixed an issue where in some cases a Node programmatically removed from a Group was not appended back to the canvas.

  • upgrade to Community edition 2.13.1

2.0.3

1st April 2020

UPDATES

  • Fixed an issue with jtk-source elements specifying endpoint: if their type definition was specifying a maxConnections for the port, the Toolkit was overwriting that with a value of -1 (unlimited connections).

  • Updated the template engine to cover a couple of edge cases when a template contains r-if statements and is updated. This only has any bearing if you use "vanilla" Toolkit and not Angular/React/Vue.

  • added support for autoSaveHandler in the Toolkit constructor and in the setAutoSave method. If you supply this then the Toolkit will decide on when an auto save needs to occur, honouring any autoSaveDebounceTimeout you supply, but your function will handle the actual save.

2.0.2

23rd March 2020

UPDATES

  • Surface correctly informs the underlying pan/zoom widget when a group has been removed.

2.0.1

20th March 2020

UPDATES

  • faster uuid method in util

  • updates to the typescript definitions.

  • Updated to Community edition 2.13.0. Versions 2.12.10 - 2.13.0 together contain:

    • a performance enhancement for painting Bezier/StateMachine connectors
    • a fix for connector overlays that can in some circumstances disappear when switching type
    • a couple of fixes related to source/target drag methods when setId or setIdChanged is used (does not affect the Toolkit edition)
    • a fix for touch events on certain Windows computers running Chrome.
  • fixed an issue rendering Groups in the React integration

2.0.0

22nd February 2020

UPDATES

  • added editable flowchart connectors
  • added editable bezier connectors
  • upgraded all flowchart demonstrations to use editable connectors and new flowchart example
  • removed legacy Vue demonstration and support
  • removed Webpack bundling demonstration (the React demonstrations use Webpack if you're looking for an example)

1.18.7

30th January 2020

UPDATES

  • Updated to Community edition 2.12.9

1.18.6

11th December 2019

UPDATES

  • Improve tracePath so that the tracing can be paused while traversing nodes.
  • Updated to Community edition 2.12.8

1.18.5

3rd December 2019

UPDATES

  • added optional onReload constructor parameter to Selection. If a generator is provided, this function is called whenever the generator has been run.
  • added optional onBeforeReload constructor parameter to Selection. If a generator is provided, this function is called before the Selection is cleared and then generator re-run.
  • added optional autoFill constructor parameter to Selection. If true, and a generator is provided, whenever a new Node is added to the Toolkit, the selection is cleared and the generator run automatically.
  • refactored the Hierarchical and Balloon layouts to extend AbsoluteBackedLayout. By default this functionality is switched off, but setting absoluteBacked:true switches it on, and then any nodes that are disconnected from all other nodes can be placed via their left and top properties. Useful for drag/drop when using these layouts.

1.18.4

30th November 2019

UPDATES

  • Added setSurface method to the SurfaceDropManager and DropManager. This allows you to use a single drop manager with multiple Surfaces.

1.18.3

29th November 2019

UPDATES

  • Upgraded to community edition 2.12.7, which contains a couple of fixes for working with the drag selection:

    • nodes inside groups cannot be added to the drag selection. Only "top level" nodes and groups can be added to the drag selection.
    • nodes in the drag selection that are subsequently added to a group are removed from the drag selection

1.18.2

16th November 2019

UPDATES

  • added addClass, hasClass and removeClass methods to the Surface widget. These wrap their corresponding methods on the underlying Community instance.

  • some internal changes to support the upcoming ability to drag flowchart connector paths.

  • updated the tracePath method to return a handler that exposes play(), pause() and cancel() methods, so the animation can be started/stopped and cancelled.

  • updated the tracePath method to support paused as an argument. When this is set to true, the animation begins in the paused state.

1.18.1

29th October 2019

UPDATES

  • updated to Community edition 2.12.5

  • Added setAutoSave(options) method to Toolkit instance, to configure auto save after instantiation. This method can be called any number of times, and each time it is called any previous auto save setup is discarded.

  • added lassoEdges:boolean constructor option for Surface widget. When true (defaults to false), edges are included in selections made with the lasso. All edges connecting any two nodes/groups (or ports on nodes/groups) that have been lassoed are included in the selection.

  • added jsPlumbToolkitLabelDragManager in an optional include, jsplumbtoolkit-labels.tgz. For a discussion of this and of labels in general, see https://docs.jsplumbtoolkit.com/toolkit/current/articles/labels.html.

1.18.0

16th October 2019

UPDATES

  • Updated the default template engine to reinstate support for custom tags. These were supported in Rotors, the original default template engine, but removed in Knockle, to which we updated recently. After some consideration we decided that custom tags can be useful, and so they're back in.

  • Added webpack dev server and associated npm script to all the React demonstrations

  • Updated the readme for licensed/evaluation distributions.

1.17.1

10th October 2019

UPDATES

  • minor updates to the way updates are handled by the text search add-on
  • fixed an issue with dragging elements from a palette on touch devices.

1.17.0

4th October 2019

UPDATES

  • removed the jsplumb-palette component from the Angular integration. It had been deprecated for a few versions. Use the drop manager instead.
  • added radius to EndpointOptions in types
  • updated eachNode, eachGroup and eachEdge mthod signature in types; they were missing the idx parameter.
  • added new full text search plugin. This is an optional import - jsplumbtoolkit-search. The data member of all nodes, groups, ports and edges is used to populate a reverse text index, which you can then search via an API. Full documentation available on https://docs.jsplumbtoolkit.com - search "text search".
  • extended the Undo/redo manager to support changes made to the dataset via the update*** methods (updateNode, updatePort etc).
  • extended the Undo/redo manager to support node/group move events. To enable these events you now need to pass a Surface to the Undo/redo manager constructor, not a Toolkit, as move events are specific to the Surface widget and not something the Toolkit deals with.

1.16.2

24th September 2019

UPDATES

  • support autoSaveDebounceTimeout parameter on Toolkit constructor. Allows requests generated by the auto save mechanism to be regulated a little.

1.16.1

23rd September 2019

UPDATES

  • added support for specifying edge label directly in an edge definition in a view (without needing to declare it as a Label overlay)
  • added support for specifying label location inside the backing data for an edge

1.16.0

UPDATES

17th September 2019

  • updated default template engine to Knockle, which is a port of the previous Rotors template engine, with some changes:

    - adds/removes content inside `r-if` and `r-each` loops when updates occur. In Rotors these elements would run

    a single time and not respond to changes in the dataset on update.

    - does not support the `r-for` element

    - does not support custom elements (Toolkit licensees are _extremely_ unlikely to be using these)

    - does not support IE8 (which the Toolkit hasnt supported for some time)
  • updates to code docs to improve generated API docs

1.15.4

30th August 2019

UPDATES

  • updated the Angular 1.x integration to use the SurfaceDropManager instead of the now deleted registerDroppableNodes method from the Surface widget.

1.15.3

18th August 2019

UPDATES

  • Updated the types of the events member of a ViewOptions object. It's not a Map; it's a plain JS object, but with a limited set of keys.

1.15.2

9th August 2019

UPDATES

  • fixed issue with Toolkit firing an edgeAdded event even when the underlying graph rejected the edge addition.

  • setting type on Edge now honours any Endpoint definitions in the new type.

1.15.1

18th July 2019

  • Update Angular code to better support situations where the 'id' property is not the one being used as node/port id.

1.15.0

17th July 2019

UPDATES

NOTE: you should use 1.15.1, and not this version. 1.15.1 has an important bugfix.

  • Removed the registerDroppableNodes method from the Surface widget. Use the drop manager package, or one of its library wrappers.

  • Updated to Community edition 2.11.0, which includes some changes to the way types are merged by the Community edition, specifically that with the exception of events and overlays, everything is overwritten when merging types. This fixes an issue with edge definitions in the Toolkit, in which anchor values were being merged rather than overridden.

  • Edge/node/port/group definitions in a View now support a mergeStrategy parameter. If set to "override", overlays and events will completely replace any overlays or events declared on parent definitions, rather than being merged with them.

1.14.11

4th July 2019

UPDATES

  • Updated the drop manager to take into account any translate CSS rules applied to ancestors of the Surface it is registered against.
  • Tested against Angular 8
  • Updated to work with the Ivy compiler in Angular 8 (need fix for Ivy bug https://github.com/angular/angular/issues/31160 in the version of Angular 8 you use)
  • Marked deprecated the registerDroppableNodes method of Surface, as well as JsPlumbToolkitPaletteComponent in the React integration, jsPlumbPaletteComponent in the Angular integration, and the palette mixin in the Vue integration. Use the drop manager package, or one of its library wrappers.

27th June 2019

UPDATES

  • Upgrade to Rotors 0.3.19, which supports multiple child elements in an r-html tag

1.14.9

6th June 2019

UPDATES

  • improvements to React integration:

    • avoid possible NPE in React integration's JsPlumbToolkitSurfaceComponent when default template renderer is being used

  • Added support for rectangular tiles in the tiled background of a Surface widget
  • Fixed issue that caused an error when dragging an existing edge from one source to another.

This reflects the fact that for the majority of applications, the function used to determine some object's type simply looks at the value of some given property. By providing the name of this property, rather than a typeFunction, the Toolkit is then able to write an object's type as well as read it.
  • Added support for setType method
