Interface: GraphNode<I, O>

Defined in: src/core-flow/Graph.ts:147

One node of the graph: an id, the runner that does the work, and — when the node has more than one parent — how to merge what those parents produced into this node's input.

Type Parameters

I

I = unknown

O

O = unknown

Properties

id

readonly id: string

Defined in: src/core-flow/Graph.ts:149

Unique within the graph. Used as the results key and the chart node id.

---

join?

readonly optional join?: (upstream) => I

Defined in: src/core-flow/Graph.ts:160

Merge upstream outputs into this node's input. upstream is keyed by PARENT NODE ID, and each value is that parent's output, unchanged.

Optional for a node with 0 or 1 parents (a single parent's output is passed through). REQUIRED when a node has 2+ parents — a silent merge is a wrong merge, so the build refuses and names the node.

Parameters

upstream

Readonly<Record<string, unknown>>

Returns

I

---

name?

readonly optional name?: string

Defined in: src/core-flow/Graph.ts:162

Human-friendly label for events + topology. Default: the node id.

---

runner

readonly runner: Runner<I, O>

Defined in: src/core-flow/Graph.ts:151

The work. Any Runner: LLMCall, Agent, a Sequence, another graph.
