Go-style error handling for TypeScript: return errors as values instead of throwing. Functions return an Error | T union, and checks use instanceof Error to narrow types, enabling flat control flow and explicit error handling. The errore toolkit provides helpers like createTaggedError, matchError, findCause, and partition to compose robust, typed error strategies without heavy wrappers or monads.
Install the errore library and adopt Go-style error handling by returning errors as values in your TS code.

To handle TypeScript errors as values, you return an Error | T union from functions and use instanceof Error to narrow types, enabling flat control flow and explicit error handling without try-catch blocks.
The best way to implement typed error handling in TypeScript is using Go-style returns where functions return Error | T, applying tagged errors with cause chains to ensure predictable, type-safe failure propagation in API clients.
Yes, you can trace error cause chains in TypeScript without heavy monads by creating tagged errors and using utilities like findCause and matchError to compose robust, typed error strategies cleanly.
You adapt third-party library throws into predictable TypeScript errors by using boundary adapters at async boundaries, catching exceptions and returning them as explicit Error | T values for safe control flow.
No, adopting Go-style error handling in TypeScript does not require external dependencies, as the errore toolkit operates with zero dependencies to provide typed error utilities like partition and matchError.
To separate successful results from errors in TypeScript data-fetching code, you use the partition utility to split an array of Error | T outcomes into distinct errors and successes for clean processing.
