effect-facet-unstable-workers-workerrunner

name: effect-facet-unstable-workers-workerrunner description: Guidance for facet effect/unstable/workers/WorkerRunner focused on APIs like WorkerRunner, PlatformMessage, and WorkerRunnerPlatform. Load after effect-skill-router when this facet is the primary owner.

Effect Facet unstable/workers/WorkerRunner

Owned scope

• Owns only effect/unstable/workers/WorkerRunner.
• Parent module: effect/unstable/workers.
• Source anchor: packages/effect/src/unstable/workers/WorkerRunner.ts.

What it is for

• Module-specific APIs and usage patterns for Effect programs.

API quick reference

• WorkerRunner
• PlatformMessage
• WorkerRunnerPlatform
• Full API list: references/api-reference.md

How to use it

• Keep runtime/execute APIs at edges; compose pure transformations before execution.
• Assume unstable APIs can evolve quickly; isolate usage behind thin local adapters.
• Use the reference docs to select the smallest API surface that solves your task.
• Validate behavior against existing tests before introducing new usage patterns.

Starter example

import { WorkerRunner } from "effect/unstable/workers/WorkerRunner";

const value = WorkerRunner.WorkerRunner();
const next = WorkerRunner.WorkerRunnerPlatform(value);

Common pitfalls

• Unstable module contracts may change; avoid coupling core app logic directly to experimental details.
• Prefer explicit, typed combinators over ad-hoc casting or unchecked assumptions.

Not covered here

• Sibling facets under the same parent are out of scope:
  • effect-facet-unstable-workers-transferable (effect/unstable/workers/Transferable)
  • effect-facet-unstable-workers-worker (effect/unstable/workers/Worker)
  • effect-facet-unstable-workers-workererror (effect/unstable/workers/WorkerError)
• Parent module ownership belongs to effect-module-unstable-workers.

Escalate to

• effect-module-unstable-workers for parent module-wide workflows.
• effect-skill-router for cross-module routing and ownership checks.
