1.10.1

Patch Changes

1.10.0

Minor Changes

  • #579 b8d3241 Thanks @bcakmakoglu! - Allow setting padding option for node.extent: 'parent'

    Padding can be a number[] containing a maximum of 4 values. The values are applied in the same order as CSS padding: top, right, bottom, left. You can omit values at the end of the array, so [10, 20] is equivalent to [10, 20, 10, 20] etc.

    Usage 

    const nodes = ref([
  {
    id: "4",
    label: "Node 4",
    position: { x: 320, y: 200 },
    style: {
      backgroundColor: "rgba(255, 0, 0, 0.7)",
      width: "300px",
      height: "300px",
    },
  },
  {
    id: "4a",
    label: "Node 4a",
    position: { x: 15, y: 65 },
    class: "light",
    extent: {
      range: "parent",
      // apply 10 px padding to all four sides
      padding: [10],
    },
    parentNode: "4",
  },
]);

Patch Changes

  • #578 c0d9018 Thanks @bcakmakoglu! - Allow omitting width and height style properties for parent nodes when using expandParent on child nodes

  • #574 1160d3d Thanks @bcakmakoglu! - Remove nodes property from ConnectionLineProps - use getNodes inside the component instead ⚠️

1.9.3

Patch Changes

1.9.2

Patch Changes

1.9.1

Patch Changes

1.9.0

Minor Changes

  • #557 c7897a1 Thanks @bcakmakoglu! - Allow customizing the controls of the viewport and the selection box.

    Props

    • selectionKeyCode: You can now set this to MaybeRef<boolean> to enable a selection box without extra button press (need to set :pan-on-drag="false" or :pan-on-drag="[2]"[RightClick]).
    • panOnDrag: Can now be a boolean or a number[], this allows you to configure every mouse button as a drag button. [1, 2] would mean that you can drag via middle and right mouse button.
    • panActivationKeyCode: Key code (or KeyFilter) for activating dragging (useful when using selectionOnDrag).
    • selectionMode: You can choose if the selection box needs to contain a node fully (SelectionMode.Full) or partially (SelectionMode.Partial) to select.

    Events

    • onSelectionStart: Emitted when the selection box is started.
    • onSelectionEnd: Emitted when the selection box is ended.
    • onViewportChangeStart: Emitted when viewport change has started.
    • onViewportChange: Emitted when viewport is changed.
    • onViewportChangeEnd: Emitted when viewport change has ended.

Patch Changes

  • #558 bac9893 Thanks @bcakmakoglu! - ⚠️ Deprecate options API utils addEdge and updateEdge. These utils will be removed soon!

    Resolve deprecation warnings

    Instead of using these utils, use addEdges and updateEdge found on the VueFlow store instance. You receive a store instance by using either a template-ref or listening to the onPaneReady event.

    Example 

    <script>
import { VueFlow } from "@vue-flow/core";

export default defineComponent({
  name: "OptionsAPIExample",
  components: { VueFlow },
  data() {
    return {
      vueFlow: null,
      instance: null,
      elements: [
        {
          id: "1",
          type: "input",
          label: "Node 1",
          position: { x: 250, y: 5 },
          class: "light",
        },
        {
          id: "2",
          label: "Node 2",
          position: { x: 100, y: 100 },
          class: "light",
        },
        {
          id: "3",
          label: "Node 3",
          position: { x: 400, y: 100 },
          class: "light",
        },
        {
          id: "4",
          label: "Node 4",
          position: { x: 400, y: 200 },
          class: "light",
        },
        { id: "e1-2", source: "1", target: "2", animated: true },
        { id: "e1-3", source: "1", target: "3" },
      ],
    };
  },
  methods: {
    // You can listen to `onPaneReady` to get the instance
    onPaneReady(instance) {
      instance.fitView();
      this.instance = instance;
    },
    onConnect(params) {
      // either use the instance you have saved in `onPaneReady`
      this.instance?.addEdges([params]);

      // or use the template-ref
      this.$refs.vueFlow?.addEdges([params]);
    },
  },
});

  • #557 c7897a1 Thanks @bcakmakoglu! - Add a11y support to selection box

1.8.0

Minor Changes

Patch Changes

A11y

This release brings A11y support to Vue Flow. All nodes and edges can now receive a focusable and ariaLabel prop, which can be used to enhance A11y experience. You can also enable focusable globally by using nodesFocusable or edgesFocusable. Additionally, nodes can be moved using keyboard controls (Arrow-Keys).

Props

  • disableKeyboardA11y: Use this prop to disable Keyboard controls on the graph.
  • defaultViewport: The old defaultZoom and defaultPosition props have been merged into a single object called defaultViewport.
  • nodesFocusable: Globally enable that nodes can be focused.
  • edgesFocusable: Globally enable that edges can be focused.

Elements

  • focusable: Enable focusing for a single node/edge by setting this option.
  • ariaLabel: Specify an aria label for a node/edge

Minor Changes

  • #394 1403b65 Thanks @bcakmakoglu! - Add nodesInitialized event hook

  • #387 9530290 Thanks @bcakmakoglu! - Pass node intersections to node drag events (on single node drag)

  • #387 a19b458 Thanks @bcakmakoglu! - Add intersection utils to help with checking if a node intersects with either other nodes or a given area

    Usage

    • You can either use the action getIntersectingNodes to find all nodes that intersect with a given node
    const { onNodeDrag, getIntersectingNodes, getNodes } = useVueFlow();

onNodeDrag(({ node }) => {
  const intersections = getIntersectingNodes(node).map((n) => n.id);

  getNodes.value.forEach((n) => {
    // highlight nodes that are intersecting with the dragged node
    n.class = intersections.includes(n.id) ? "highlight" : "";
  });
});
    • Node drag events will provide you with the intersecting nodes without having to call the action explicitly.
    onNodeDrag(({ intersections }) => {
  getNodes.value.forEach((n) => {
    n.class = intersections?.some((i) => i.id === n.id) ? "highlight" : "";
  });
});
    • Or you can use the isIntersecting util to check if a node intersects with a given area
    const { onNodeDrag, isNodeIntersecting } = useVueFlow();

onNodeDrag(({ node }) => {
  // highlight the node if it is intersecting with the given area
  node.class = isNodeIntersecting(node, {
    x: 0,
    y: 0,
    width: 100,
    height: 100,
  })
    ? "highlight"
    : "";
});

  • #396 03412ac Thanks @bcakmakoglu! - Add zoomable and pannable to MiniMap

    Usage

    • Set zoomable and pannable to true in MiniMap component to enable interactions with the MiniMap
    <template>
  <VueFlow v-model="elements">
    <MiniMap :zoomable="true" :pannable="true" />
  </VueFlow>
</template>

Patch Changes

  • #361 43ff2a4 Thanks @bcakmakoglu! - Add EdgeLabelRenderer component export

    Usage

    • You can use the EdgeLabelRenderer component to render the label of an edge outside the SVG context of edges.
    • The EdgeLabelRenderer component is a component that handles teleporting your edge label into a HTML context
    • This is useful if you want to use HTML elements in your edge label, like buttons
    <script lang="ts" setup>
import type { EdgeProps, Position } from "@vue-flow/core";
import { EdgeLabelRenderer, getBezierPath, useVueFlow } from "@vue-flow/core";
import type { CSSProperties } from "vue";

    connectable: "single", // each handle is only connectable once (default node for example)
  },
  {
    id: "2",
    position: { x: 200, y: 0 },

    • Edges not returned by getter when paneReady event is triggered

1.0.0

Major Changes

  • #305 939bff50 Thanks @bcakmakoglu! - # What's changed?

    • Simplify edge path calculations
      • remove getEdgeCenter and getSimpleEdgeCenter

    Breaking Changes

    • getEdgeCenter has been removed
      • Edge center positions can now be accessed from getBezierPath or getSmoothStepPath functions

    Before:

    import { getBezierPath, getEdgeCenter } from "@braks/vue-flow";

// used to return the path string only
const edgePath = computed(() => getBezierPath(pathParams));

// was necessary to get the centerX, centerY of an edge
const centered = computed(() => getEdgeCenter(centerParams));

    After:

    import { getBezierPath } from "@vue-flow/core";

// returns the path string and the center positions
const [path, centerX, centerY] = computed(() => getBezierPath(pathParams));

  • #305 47d837aa Thanks @bcakmakoglu! - # What's changed?

    • Change pkg scope from 'braks' to 'vue-flow'
      • Add @vue-flow/core package
      • Add @vue-flow/additional-components package
      • Add @vue-flow/pathfinding-edge package
      • Add @vue-flow/resize-rotate-node package

    Features

    • useNode and useEdge composables
      • can be used to access current node/edge (or by id) and their respective element refs (if used inside the elements' context, i.e. a custom node/edge)
    • selectionKeyCode as true
      • allows for figma style selection (i.e. create a selection rect without holding shift or any other key)
    • Handles to trigger handle bounds calculation on mount
      • if no handle bounds are found, a Handle will try to calculate its bounds on mount
      • should remove the need for updateNodeInternals on dynamic handles
    • Testing for various features using Cypress 10

    Bugfixes

    • Fix removeSelectedEdges and removeSelectedNodes actions not properly removing elements from store

    Breaking Changes

    • @vue-flow/core package is now required to use vue-flow
    • @vue-flow/additional-components package contains Background, MiniMap and Controls components and related types
      • When switching to the new pkg scope, you need to change the import path.

    Before:

    import { VueFlow, Background, MiniMap, Controls } from "@braks/vue-flow";

    After

    import { VueFlow } from "@vue-flow/core";
import {
  Background,
  MiniMap,
  Controls,
} from "@vue-flow/additional-components";
