Simple scalable state management.


MobX is a field-proven library that makes state management simple and scalable through the transparent application of functional reactive programming (TFRP).

The MobX philosophy is simple:

Simple πŸ˜™#

Write minimalist, boilerplate-free code that reflects your intent. Trying to update a record field? Use good old JavaScript assignment. Updating data in an asynchronous process? No special tools are required, the reactivity system will detect all your changes and propagate them to where they are used.

Optimal rendering effortlessly πŸš…#

All changes and usage of your data are tracked at runtime, creating a dependency tree that captures all relationships between state and output. This ensures that your state-specific computations, such as React components, are only done when strictly necessary. There is no need to manually optimize components using error prone and suboptimal techniques like memoization and selectors.

Architectural freedom πŸ€ΉπŸ»β€#

MobX is obscure and allows you to manage the state of your application outside of any UI framework. This makes your code independent, portable, and above all, easily testable.

Installing dependencies#

MobX 6 has released a compatible companion package mobx-react-lite @ 3, which supports React Hooks and functional components.

We will also install the nanoid library for creating unique id and a library with the checkbox component @ react-native-community / checkbox

npm install mobx mobx-react-lite nanoid @react-native-community/checkbox

Enabling decorators#

To use decorators, follow these steps.


Include the ExperimentalDecorators compiler option in tsconfig.json, or pass it to the compiler as the --experimentalDecorators flag. You must target es5 + (es5, es6, ...) using the target parameter or the --target flag.

React Native#

When using c react native the following preset can be used

npm install @babel/plugin-proposal-decorators
