React flow node ts

React Flow Node

Create React Flow node components following established patterns with proper TypeScript types and store integration.

Quick Start

Copy templates from assets/ and replace placeholders:

• {{NodeName}} → PascalCase component name (e.g., VideoNode)
• {{nodeType}} → kebab-case type identifier (e.g., video-node)
• {{NodeData}} → Data interface name (e.g., VideoNodeData)

Templates

• assets/template.tsx - Node component
• assets/types.template.ts - TypeScript definitions

Node Component Pattern

export const MyNode = memo(function MyNode({
  id,
  data,
  selected,
  width,
  height,
}: MyNodeProps) {
  const updateNode = useAppStore((state) => state.updateNode);
  const canvasMode = useAppStore((state) => state.canvasMode);
  
  return (
    <>
      <NodeResizer isVisible={selected && canvasMode === 'editing'} />
      <div className="node-container">
        <Handle type="target" position={Position.Top} />
        {/* Node content */}
        <Handle type="source" position={Position.Bottom} />
      </div>
    </>
  );
});

Type Definition Pattern

export interface MyNodeData extends Record<string, unknown> {
  title: string;
  description?: string;
}

export type MyNode = Node<MyNodeData, 'my-node'>;

Integration Steps

1. Add type to src/frontend/src/types/index.ts
2. Create component in src/frontend/src/components/nodes/
3. Export from src/frontend/src/components/nodes/index.ts
4. Add defaults in src/frontend/src/store/app-store.ts
5. Register in canvas nodeTypes
6. Add to AddBlockMenu and ConnectMenu
