defineNodeTemplate

defineNodeTemplate<P>(template): ComponentType<WorkflowNodeTemplateProps>

Erases the per-schema P parameter from a typed node template so it can be stored in a NodeTemplatesMap without consumer-side casts.

The cast is safe in practice: SDK only mounts a template for a node whose palette schema produces P. The pair (palette item, template) carries the runtime guarantee; TypeScript cannot express that link, so we erase the parameter here in one well-documented spot.

Type Parameters

P

P

Parameters

template

ComponentType<WorkflowNodeTemplateProps<P>>

Returns

ComponentType<WorkflowNodeTemplateProps>

Example

type MultiPortProperties = NodeDataProperties<typeof multiPortSchema>;

export const MultiPortNodeTemplate = defineNodeTemplate<MultiPortProperties>(
  memo(({ data }: WorkflowNodeTemplateProps<MultiPortProperties>) => {
    const status = data?.properties.status ?? 'active';
    return <NodePanel.Root>…</NodePanel.Root>;
  }),
);
