@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.
Redux is a predictable state container for JavaScript apps, commonly used with libraries like React or Angular for managing application state. It follows a unidirectional data flow pattern, making it easier to understand how data changes in the application over time. Redux provides a single source of truth for the application state, which helps in debugging and testing.
@ngrx/store is heavily inspired by Redux and follows the same Flux architecture pattern. It provides a centralized store to manage the application state using reducers, actions, and selectors. Redux, on the other hand, is one of the most popular state management libraries that implements the Flux pattern.
Popularity and Ecosystem
Redux has been around longer and has a larger user base and ecosystem. It has wide community support, a rich set of middleware, and numerous Redux-related libraries, tools, and extensions available. @ngrx/store is a library specifically built for Angular applications and is widely adopted within the Angular ecosystem. While it might not have the same level of popularity and vast ecosystem as Redux, it has a strong community backing within the Angular community.
Integration with Framework
@ngrx/store is designed specifically for Angular applications and integrates seamlessly with Angular's ecosystem, providing Angular-specific features like integration with Angular Router and Angular Effects for handling side effects. Redux is a framework-agnostic library and can be used with any JavaScript framework or even without a framework. It provides a pure JavaScript implementation of state management.
Developer Experience
Both libraries have solid developer experiences. Redux provides a simple and intuitive API, making it easy to understand and work with. It has excellent documentation and numerous resources available. @ngrx/store, being an Angular-specific library, leverages Angular's dependency injection mechanism to provide a streamlined developer experience. It provides strong typings and a tight integration with Angular's tooling.
Performance
Both libraries offer good performance when used correctly. However, @ngrx/store has some optimizations specifically tailored for Angular, such as change detection strategies and OnPush change detection. Redux is a more general-purpose library and doesn't have Angular-specific optimizations by default.
Learning Curve
Redux has a steeper learning curve compared to @ngrx/store, mainly due to its conceptual complexity and the need to understand concepts like reducers, actions, and middleware. @ngrx/store, being Angular-specific, provides a more opinionated and streamlined approach to state management, which can make it easier for Angular developers to get started quickly.
