Methods

resolveRef()

resolveRef(id: string): Promise<StepPayload>;

Defined in: src/batteries/media/runtime.ts:73

Resolve another media participating in this step (merge/diff targets), by ref id. Supplied by the pipeline from its configured media resolver.

Parameters

Parameter	Type
id	string

Returns

Promise<StepPayload>

---

shortCircuit()

shortCircuit(payload: StepPayload): never;

Defined in: src/batteries/media/runtime.ts:66

Short-circuit this step: skip the implementation and continue the chain with bytes (the cache idiom). Throws internally — call it, don't return it.

Parameters

Parameter	Type
payload	StepPayload

Returns

never
