Typesafe API Call Utility

library 5.1.2 ·javascript
verified May 27, 2026

typesafe-api-call is a minimalistic JavaScript library designed to streamline API interactions by enforcing typesafety and a functional programming paradigm. It abstracts away traditional exception handling, instead ensuring that every API call resolves to an explicit `APISuccess` or `APIFailure` result, compelling developers to handle both successful and unsuccessful outcomes distinctly. The library is currently on version 5.1.2 and appears to have an active release cadence, with recent patches and new features like `callWithRetries` introduced in minor versions. A key differentiator is its emphasis on functional results over exceptions, promoting predictable state management. It also integrates seamlessly with complementary tools like `type-decoder` and `type-crafter` to facilitate YAML-driven type and decoder generation, further enhancing end-to-end typesafety for API responses.
