Function defineNode

Declares a reusable node type and returns a factory for it.

const Stats = defineNode({
  kind: 'stats',
  inputs: { series: port<TimeSeries<Schema>>() },
  outputs: { mean: port<number>(), max: port<number>() },
  compute: ({ series }) => ({
    mean: series.column('cpu').mean(),
    max: series.column('cpu').max(),
  }),
});

const stats = Stats();
raw.out.value.connect(stats.in.series);
stats.out.mean.get();
Copy

For a node type that needs per-instance configuration, close over it: const smoother = (span: number) => defineNode({ ... })();
