A Tree-Shakable Result Library
- The Result type addresses the lack of statically typed thrown errors in TypeScript, offering a way to model success and failure in a function's return value.
- Libraries like neverthrow, effect-ts, and fp-ts provide this functionality, with trade-offs in simplicity, maintenance, complexity, and bundle size.
- @praha/byethrow is a new library focused on the Result type, aiming to be simple, tree-shakable, and lightweight.
- It represents Result values as plain objects, allowing safe serialization to JSON and easy processing at server-client boundaries.
- @praha/byethrow's unified API, both synchronous and asynchronous, offers a consistent interface for handling results.
- The library provides well-documented functions with TSdoc-based examples and an online API reference for quick adoption.
- Usage scenarios are discussed, emphasizing the need for handling expected errors predictably with Result while allowing other exceptions to be thrown and logged.
- @praha/byethrow caters to developers seeking type-safe error handling without the complexity of existing libraries like neverthrow, effect-ts, or fp-ts.
- The library is recommended for those finding other options lacking or overly heavy, and users are encouraged to support the project by starring the repository.
