Effect-TS is a functional TypeScript library providing typed effects, structured concurrency, and a robust runtime. This skill covers correct usage patterns and addresses common misconceptions from LLM-generated content.
LLM outputs often contain incorrect APIs. Use this table to correct them:
| Effect.cachedWithTTL(...) | Cache.make({ timeToLive: Duration }) | | Effect.cachedInvalidateWithTTL(...) | cache.invalidate(key) / cache.invalidateAll() | | Effect.match(...) | Effect.either + Either.match, or Effect.catchTag | | "thread-local storage" | "fiber-local storage" via FiberRef | | JSON Schema Draft 2020-12 | @effect/schema generates Draft-07 |
