createTypeMatchValidator

createTypeMatchValidator(options?): (source, target, info) => boolean

Defined in: src/components/editor/NodeGraph/createTypeMatchValidator.ts:47

Build an isValidConnection validator for the common “connect ports of matching dataType, in an allowed direction” rule — the logic most node editors hand-write. Drop the result straight onto <NodeGraph>:

const isValidConnection = useMemo(() => createTypeMatchValidator(), []);
<NodeGraph isValidConnection={isValidConnection} />

The default match accepts a connection when either port is untyped, the two dataTypes are equal, or one side is the anyType token. Override match for richer rules (subtype graphs, numeric coercion, etc.).
