Yeah! Svelte Flow 1.0. is here 🚀 It is based on Svelte 5 and introduces a lot of new features and improvements. Please refer to the migration guide to see how to upgrade.

New features

  • Reconnect edges: You can reconnect your edges by using the new <EdgeReconnectAnchor /> component. It can be used to add custom reconnection points on custom edges.
  • Keyboard navigation & A11y: We added support for keyboard navigation and improved accessibility for screen readers. You can now tab through nodes and edges and move nodes with the arrow keys. Can be disabled via disableKeyboardA11y
  • Click connect: You can now create a new connection by clicking on a handle one by one.
  • Enhanced ViewportPortal: You can now decide if you want to render something below or above the nodes & edges in the viewport.
  • Improved fitView: We finetuned the fitView function to better work with dynamically added nodes.
  • colorModeSSR prop: You can pass a fallback color mode for server side rendering when colorMode is set to 'system'.
  • elevateNodesOnSelect & elevateEdgesOnSelect: Control if nodes & edges should be elevated via z-index when selected.
  • noDragClass, noWheelClass, noPanClass: You can now modify the class name used to disable dragging, panning and zooming.
  • onselectionchange & useOnSelectionChange: You can now listen to selection changes via a callback

0.1.0

This is a bigger update for Svelte Flow to keep up with the latest changes we made for React Flow and the Svelte5 rewrite. The biggest change is the separation of user nodes (type Node) and internal nodes (type InternalNode), which includes a renaming of the node.computed attribute to node.measured. In the previous versions, we stored internals in node[internalsSymbol]. This doesn't exist anymore, but we only add it to our internal nodes in node.internals..

⚠️ Breaking

  • rename node.computed to node.measured - this attribute only includes width and height and no positionAbsolute anymore. For this we added the helpers getInternalNode and useInternalNode
  • rename node.parentNode to node.parentId

More updates:

  • add isValidConnection for <Handle /> component
  • add fitViewOptions for <Controls /> component
  • add getInternalNode to useSvelteFlow
  • add useInternalNode hook
  • don't reset nodes and edges when svelte flow unmounts - thanks @darabos
  • fix node event types - thanks @RedPhoenixQ
  • make handleId and isTarget reactive - thanks @darabos
  • fix MiniMap interaction for touch devices
  • fix pane: pinch zoom on windows
  • fix nodes: return user node in node event handlers

0.0.41

  • fix: re-observe nodes when not initialized

0.0.40

  • add orientation ('horizontal' or 'vertical'), style and class prop for Controls component
  • allow multiple keys for deleteKey, selectionKey, multiSelectionKey, panActivationKey and zoomActivationKey
  • fix node observe / unobserve
  • fix edge and node types
  • active context menu releases pressed keys to reset selection

0.0.39

⚠️ Breaking changes

  • on:nodedragstart, on:nodedrag and on:nodedragstop are also getting fired if a selection bix is being dragged. We renamed the node param to targetNode and set it to null if a selection is being dragged.

Patch changes

  • export EdgeLabel component
  • add "connectionindicator" class for Handle component
  • address a11y warnings

0.0.38

⚠️ Breaking changes

  • NodeProps generic is a node and not only node data. type $$Props = NodeProps<AppNode>

Patch changes

  • unify Edge and Node type handling
  • fix safari: prevent selection of viewport

0.0.37

⚠️ Breaking changes

  • useNodesData not only returns data objects but also the type and the id of the node
  • status class names for Handle components are slightly different. It's now "connectingfrom" and "connectingto" instead of "connecting"

Patch changes

  • better cursor defaults for the pane, nodes and edges
  • add initialWidth and initialHeight node attributes for specifying initial dimensions for ssr
  • always re-measure nodes when new nodes get passed
  • fix NodeResizer when used in combination with nodeOrigin

0.0.36

Patch changes

  • a better NodeResizer (child nodes do not move when parent node gets resized)
  • fix on:panecontextmenu
  • add role="button" to <EdgeLabel /> to prevent a11y warnings
  • don't delete node when input is focused and user presses Backspace + Ctrl (or any other mod key)
  • useHandleConnections: use context node id when no node id is passed
  • don't trigger drag start / end when node is not draggable

0.0.35

Minor changes

  • add getNode, getNodes, getEdge and getEdges to useSvelteFlow
  • add useInitialized / useNNodesInitialized hooks and oninit handler

Patch changes

  • selection box is not interrupted by selectionKey being let go
  • Edge label has a default background and is clickable
  • do not use fallback handle if a specific id is being used
  • use correct id for <Handle /> data-id attribute
  • fix getNodesBounds and add second param for passing options

0.0.34

Minor changes

  • add second option param to screenToFlowPosition for configuring if snapToGrid should be used
  • add slot to Controls

Patch changes

  • cleanup ControlButton types
  • infer types for getIncomers, getOutgoers, updateEdge, addEdge and getConnectedEdges thanks @joeyballentine
  • refactor handles: prefix with flow id for handling nested flows
  • add comments for types like SvelteFlowProps or Node for a better developer experience

0.0.33

Bugfix

  • fix deleteElements
  • fix dragging when draggable=false
  • add ariaLabel prop for <Controls />

⚠️ Breaking

  • deleteElements function now takes one object as an argument { nodes: [], edges: [] } instead of two (nodes, edges)

0.0.32

Features

  • add NodeResizer and NodeResizeControl components for resizing nodes

0.0.31

Bugfix

  • fix edge rendering

0.0.30

Features

Patch changes

  • new nodeDragThreshold default is 1
  • refactor/simplify edge rendering

0.0.29

Another huge update for Svelte Flow 🙏 Handling data flows will be way easier with the new hooks and functions. You can now subscribe to connected nodes, receive data and update nodes more easily. We fix a big issue about the <Handle /> component. No more on:connect that only worked for target <Handle /> components but onconnect and ondisconnect that works for every <Handle />.

Features

  • add useHandleConnections hook for receiving connected node and handle ids for a specific handle
  • add useNodesData(ids: string | string[]) hook for receiving data from other nodes
  • export updateNode and updateNodeData from useSvelteFlow to update a node or the data object
  • add onedgecreate function for passing a certain id or other attributes to a newly created edge

⚠️ Breaking

  • replace on:connect, on:connectstart and on:connectend with onconnect, onconnectstart and onconnectend, no need to forward on:connect.. anymore

Fixes and minor changes

  • onconnect and ondisconnect callback work for <Handle /> component
  • don't delete a node when user presses Backspace inside an input/textarea/.nokey element
  • bgColor prop for Background didn't work
  • prefix css vars with "xy-"
  • don't update nodes and edges on pane click if not necessary
  • cleaner types for exported edges
  • fix getIntersectingNodes bug when passing Rect

0.0.28

This is a huge update! We added a new <NodeToolbar /> component and a new colorMode ('light' | 'dark' | 'system') prop for toggling dark/light mode.

There are also some breaking changes again (sorry!) but we are very close to the final API for Svelte Flow 1.0.0. The biggest change is that we group node attriubutes (width, height, positionAbsolute) that are added by the library under node.computed. This makes it easier to understand, that this stuff comes from the library itself. node.width and node.height is still an optional node option and can be used to set certain dimensions for SSR or on the client.

  • add <NodeToolbar /> component
  • add on:selectionclick and on:selectioncontextmenu event handlers
  • add ondelete({ nodes, edges }) handler
  • add zoomActivationKey prop
  • add width and height prop to custom NodeProps type
  • add colorMode prop ('light' | 'dark' | 'system')
  • ⚠️ replace xPos and yPos with positionAbsolute prop to custom NodeProps type
  • ⚠️ node.width/height and node.positionAbsolute can now be found under node.computed.width/height/positionAbsolute
  • ⚠️ node.width/height is still optional an can be used for forcing certain dimensions and SSR
  • refactor keys: you can now disable keys by setting them to null (e.g. selectionKey={null})
  • performance optimization with internal node lookup

0.0.27

  • add selectionOnDrag prop - can be used to create figma-like controls in combination with panOnDrag={false} / panOnDrag={[1, 2]} + panOnScroll={true}
  • ⚠️ rename screenToFlowCoordinate to screenToFlowPosition
  • ⚠️ rename flowToScreenCoordinate to flowToScreenPosition
  • ⚠️ rename getTransformForBounds to getViewportForBounds (return { x: number, y: number, zoom: number } instead of [number, number, number])
  • ⚠️ rename getRectOfNodes to getNodesBounds
  • simplify handle default styles, so that it's easier to override them
  • added e2e tests

Svelte Flow alpha is here 🔥 You can expect some changes until we reach 1.0.0 but we try to stick as close as possible to the React Flow API. There are no docs yet, but we are working on it! For now the easiest way is to use the autocomplete of your IDE, lookup the props in the SvelteFlow component or check out the React Flow docs.

This very first release comes with lots of features already:

  • pass nodes and edges as writables
  • draggable, selectable and deletable nodes
  • support for custom nodeTypes and edgeTypes
  • basic viewport settings like fitView, minZoom and maxZoom
  • additional components: <MiniMap />, <Controls /> & <Background />
