Defined in: packages/pubsub/src/types.ts:214

Context passed to each PubSubInterceptor in the chain.

This is a discriminated union keyed on operation. Narrowing on ctx.operation gives access to the operation-specific fields.

publish and handle wrap user-facing operations where interceptor errors propagate. All other operations are transport lifecycle notifications where interceptor errors are caught to avoid breaking delivery flow.

Type Declaration

optional contextValues?: ContextValues
