@ngrx/store is a state management library for Angular applications. It provides a predictable state container that follows the Redux pattern, allowing you to manage the state of your application in a centralized and immutable way. With @ngrx/store, you can define actions and reducers to update the state, and use selectors to retrieve specific parts of the state.
React Query is a popular library used for managing server state outside of React components. It provides a simple, powerful, and fast solution for fetching, caching, and updating data in your application. React Query aims to improve the performance of your application by reducing network requests and minimizing the amount of duplicated code often associated with managing data fetching and caching.
Both @ngrx/store and react-query are popular npm packages in their respective ecosystems. @ngrx/store is widely used in the Angular community, while react-query is popular among React developers. The popularity of both packages is evident from their active communities and adoption in production projects.
Purpose and Functionality
@ngrx/store is a state management library specifically designed for Angular applications. It provides a reactive approach to managing state using the Redux pattern and enables predictable and centralized state management in Angular projects. On the other hand, react-query is a data-fetching library for React applications. It simplifies fetching, caching, and updating remote data in React components while providing features like intelligent caching, background data refetching, and query invalidation.
Developer Experience
Both packages aim to improve developer experience, but they do it in different ways. @ngrx/store integrates well with Angular's ecosystem, providing Angular-specific features like decorators and dependency injection. It has a well-defined pattern and is widely adopted in Angular projects. react-query, on the other hand, embraces React's functional programming paradigm and offers a hooks-based API, which fits naturally into React components. It has a simpler learning curve for React developers and provides a more concise and intuitive approach to handling asynchronous data fetching.
Performance
In terms of performance, @ngrx/store and react-query have different focuses. @ngrx/store promotes immutability and Redux-style state management, which can lead to optimized performance when used correctly. It enables efficient change detection and allows for granular control over state updates. On the other side, react-query focuses on efficient data fetching and caching. It provides intelligent caching mechanisms, reducing unnecessary network requests and improving rendering optimizations.
Integration and Ecosystem
@ngrx/store seamlessly integrates with the Angular ecosystem and works well with other @ngrx packages for features like effects and entity management. It has good tooling support and a mature ecosystem of libraries and extensions. react-query, being a React-specific library, integrates well with React components and hooks. It is adaptable and can be used with other React state management libraries like Redux or Zustand if needed. It also has good TypeScript support and a growing ecosystem of community-driven plugins and extensions.
