Function derive

Builds a single-output node and wires it to its sources in one step — the shape most graph edges take.

const smoothed = derive({ series: raw.out.value }, ({ series }) =>
  series.smooth('cpu', { method: 'ema', alpha: 0.3 }),
);
smoothed.out.value.get();
Copy

Equivalent to defineNode with one output named value, an input per source key, and the connections already made. Reach for defineNode when a node has several outputs, or when the node type is reused across graphs and deserves a name.
