custom-node-definition

Node definitions in react-wireflow require a NodeDefinition structure containing type, displayName, ports, and defaultData. You further customize visuals and interactions by implementing an optional renderNode component using NodeRendererProps.

External data handling for react-wireflow custom nodes uses optional loadExternalData and updateExternalData hooks. These hooks allow your custom node definitions to fetch and persist node-specific data dynamically during editor interactions.

Yes, you can use TypeScript to enforce a NodeDefinition contract for custom node types. This contract specifies required properties like type, displayName, and ports, ensuring type-safe node structures within TypeScript node editor projects.

The best way to customize node appearances in react-wireflow is by implementing the renderNode function with NodeRendererProps. This approach allows you to design bespoke visual components and define specific interaction behaviors for each custom node type.

No, implementing both renderNode and renderInspector is optional. You only need to define the core NodeDefinition contract with type, displayName, and ports, while renderers and external data hooks can be added as needed.
