About Observable

Observable is a lightweight, intuitive state management library that brings the power of reactivity to JavaScript with minimal effort.

Inspired by MobX but designed to be even simpler.

It gives you complete freedom to update state anywhere — even inside effects or reaction callbacks. You don’t need special wrappers, annotations, or strict rules; just modify your data naturally, and Observable will automatically track changes and update what needs to change.

You can define observable objects and classes naturally, extend them freely, and handle asynchronous operations without extra syntax. There’s no setup required. No configuration. No ceremony. Just pure, predictable reactivity — always working exactly as you expect.

Whether you're building a small app or a large-scale project, Observable keeps your code clean, expressive, and easy to maintain.
