Error Management

Handle recoverable errors in Effect-TS by defining typed errors with Schema.TaggedError and catching them using Effect.catchAll or Effect.catchTag to isolate specific failure modes. You can also recover via fallback strategies using Effect.orElse.

Defects in Effect-TS represent unrecoverable failures, while typed errors model expected domain failures on the error channel. Sandboxing allows you to catch defects and convert them into typed errors for recovery.

Accumulate multiple errors in Effect-TS by using Effect.all or Effect.validate to run effects in parallel and collect all failures instead of short-circuiting on the first error encountered.

Implement retry and timeout strategies in Effect-TS by combining typed error handling with built-in scheduling operators to build resilient asynchronous workflows that automatically recover from transient failures.

Transform error types in Effect-TS using Effect.mapError to alter the error channel or Effect.mapBoth to transform both success and error channels simultaneously while maintaining predictable failure modes.

Effect-TS supports catching errors by specific tags using Effect.catchTag for individual tagged errors or Effect.catchTags to handle multiple distinct tagged errors within a single effect pipeline.
