@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.
Recoil is a state management library for React applications developed by Facebook. It provides a simple and efficient way to manage global state in complex React applications. Recoil offers features like atoms for state definition, selectors for derived state, and the ability to subscribe to state changes. It also optimizes re-renders by tracking dependencies at the granularity of individual components.
Both @ngrx/store and Recoil are popular state management libraries in the JavaScript ecosystem. @ngrx/store is specifically designed for Angular applications and has a strong following within the Angular community. Recoil, on the other hand, is a newer library developed by Facebook and has gained popularity for its simplicity and flexibility.
Integration
While @ngrx/store is tightly integrated with Angular and follows Angular's patterns and conventions, Recoil is framework-agnostic and can be used with any JavaScript framework or library, including React, Vue, and Angular.
Developer Experience
Both libraries provide a good developer experience, but they have different approaches. @ngrx/store follows a more traditional Redux-like pattern with actions, reducers, and selectors, which can be familiar to developers already experienced with Redux. Recoil, on the other hand, introduces a new concept called atoms and selectors, which simplifies state management and reduces boilerplate code.
Performance
Recoil is designed to optimize performance by leveraging React's built-in optimizations like memoization and batching. It also provides features like selective re-rendering and asynchronous state updates. @ngrx/store also focuses on performance and provides features like memoized selectors and immutability, but it may have a slightly higher overhead due to its adherence to Redux principles.
Community and Ecosystem
Both @ngrx/store and Recoil have active communities and growing ecosystems. @ngrx/store benefits from the larger Angular ecosystem and has a wide range of community-contributed packages and extensions. Recoil, being developed by Facebook, has the advantage of being backed by a large organization and has the potential for future integrations with other Facebook libraries and tools.
Learning Curve
The learning curve for @ngrx/store can be steeper, especially for developers who are new to Redux concepts. Recoil, on the other hand, has a simpler API and requires less boilerplate code, making it easier to learn and get started with.
