error-handling

Handle typed errors in Effect TypeScript by defining custom failures with Data.TaggedError and catching them precisely using catchTag, catchTags, or catchAll to manage specific error channels and ensure exhaustive matching across your application.

The best way to catch specific tagged errors in Effect is using catchTag for individual error types or catchTags to handle multiple tags simultaneously, allowing you to target distinct failure states like UserNotFound or NetworkError without catching unrelated errors.

Implement error recovery patterns in Effect by using built-in combinators to define fallbacks, retry strategies, or error transformations, ensuring your application gracefully recovers from expected failures and maintains predictable behavior during domain-specific operations.

Use Data.TaggedgedError for error handling in TypeScript to create clear, categorized error states with distinct tags, enabling the compiler to enforce exhaustive error matching and prevent unhandled failures in your Effect programs.

You can transform errors into different types using Effect by applying error handling combinators to map domain-specific failures into alternative tagged errors or unified error channels, ensuring consistent error propagation and recovery across application layers.

Effect supports exhaustive error matching for tagged errors by leveraging catchTag and catchTags, ensuring that every potential failure state defined by Data.TaggedError is explicitly handled during compilation to prevent uncaught runtime exceptions.
