React Flow Node TS

React Flow Node

Selective Reading Rule

Start with:

• references/senior-master-standard.md
• references/usage-routing.md
• references/quality-checklist.md

Then load only the inherited docs, scripts, assets, or examples that match the user's actual task.

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

When to Use

This skill is applicable to execute the workflow or actions described in the overview.

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
