Why should I use Schema.TaggedError over standard errors?

Schema.TaggedError provides a type-safe way to define errors that can be easily filtered and handled using pattern-matching operators like catchTag, ensuring the compiler tracks which errors have been handled.

What is the difference between an error and a defect in Effect?

Errors are expected failures tracked in the type system (the error channel), while defects are unexpected bugs or runtime exceptions that are not part of the type signature and represent unrecoverable states.

How does Effect handle multiple errors at once?

Effect provides operators like Effect.partition or Effect.validate to accumulate multiple failures across a collection, allowing you to process all errors rather than stopping at the first failure.

Can I implement custom retry logic with this skill?

Yes, Effect allows for complex retry schedules using the Schedule module, supporting features like exponential backoff, jitter, and conditional retries based on specific error tags.

API 开发

Implements robust error handling in Effect TS projects using typed errors, recovery strategies, and resilient fault-tolerant patterns.

This skill provides comprehensive guidance for managing failures within the Effect ecosystem, emphasizing the distinction between recoverable expected errors and unrecoverable defects. It enables developers to implement type-safe error handling using Schema.TaggedError, utilize advanced recovery operators like catchTag and orElse, and manage complex scenarios such as error accumulation, retries with exponential backoff, and sandboxing. By following these patterns, developers can build more resilient, predictable TypeScript applications that leverage the full power of the Effect error channel for compile-time safety.
