@ngrx/store is a state management library for Angular applications, inspired by Redux. It provides a centralized store for managing the state of your application and enables predictable state management through a unidirectional data flow. With @ngrx/store, you can define actions, reducers, and selectors to manage and access application state in a structured and efficient way.

MobX is a simple, scalable, and battle-tested state management library for React applications. It provides a reactive and transparent way to manage application state, making it easy to create reactive data models that automatically update components when the data changes. MobX follows the principle of minimalistic API and maximum performance, ensuring efficient state management without boilerplate code.

Fight!

State Management

Both @ngrx/store and MobX are popular choices for state management in JavaScript applications. @ngrx/store is a state management library specifically designed for Angular applications, while MobX is a more general-purpose state management library that can be used with any JavaScript framework or library.

Developer Experience

Both libraries offer a good developer experience, but they have different approaches. @ngrx/store follows a more structured and opinionated approach, providing a clear separation of concerns and enforcing a unidirectional data flow. MobX, on the other hand, offers a more flexible and intuitive API, allowing developers to manage state in a more reactive and mutable way.

Learning Curve

The learning curve for @ngrx/store can be steeper, especially for developers who are new to Angular or Redux-like state management. It requires understanding concepts like actions, reducers, and selectors. MobX, on the other hand, has a relatively lower learning curve, as it relies on observable data and provides a simpler API for managing state.

Performance

Both libraries are known for their good performance. However, MobX is often praised for its highly efficient reactivity system, which only updates the necessary parts of the application when state changes. @ngrx/store, being based on Redux principles, also offers good performance optimizations like memoized selectors and immutability.

Community and Ecosystem

Both @ngrx/store and MobX have active communities and ecosystems. @ngrx/store benefits from being part of the Angular ecosystem, which has a large and supportive community. It also integrates well with other Angular libraries and tools. MobX, on the other hand, has a broader reach and can be used with various frameworks and libraries, making it more versatile in terms of ecosystem support.
