Reliable TypeScript for the AI era
A full functional-TS ecosystem: errors, concurrency and retries as values, with Effect 4 maturing.
The functional-effect library for TypeScript: errors, retries, concurrency and resources as typed values, with a runtime that makes them compose. Effect 4 hardens it into a full platform (schema, queue, workflow). Steep curve, exceptional ceiling: the 'serious TypeScript' school.
Who it's for
TypeScript developers who want rigorous, type-safe handling of errors, concurrency and side effects.
