Interface NodeSpec<In, Out>

Declares a reusable node type. Passed to defineNode.

interface NodeSpec<In extends PortSpecMap, Out extends PortSpecMap> {
    inputs: In;
    kind: string;
    outputs: Out;
    compute(inputs: PortValues<In>): PortValues<Out>;
}

Type Parameters

In extends PortSpecMap
Out extends PortSpecMap

`Readonly`inputs

inputs: In

`Readonly`kind

kind: string

Stable identifier for this node type, used in errors and toJSON().

`Readonly`outputs

outputs: Out

Methods

compute

compute(inputs: PortValues<In>): PortValues<Out>
Produces every declared output from the current input values.

Called only when an input version actually changed. Must be a pure function of its inputs — the engine caches the result and will not call it again until something upstream moves.
Parameters
- inputs: PortValues<In>
Returns PortValues<Out>
