@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.
Jotai is a simple and scalable state management library for React applications. It offers a minimalistic and flexible approach to managing state by using atoms, derived atoms, and actions. Jotai leverages React's context API to provide a lightweight and efficient solution for state management without the need for additional dependencies like Redux or MobX.
Both @ngrx/store and Jotai are popular npm packages, but @ngrx/store has been around for longer and has a stronger presence within the Angular ecosystem. It is widely used in Angular projects and has a large community following. Jotai, on the other hand, is a newer library that gained popularity due to its simplicity and flexibility.
Framework Compatibility
@ngrx/store is specifically designed for managing state in Angular applications. It integrates seamlessly with Angular and follows Angular's reactive architecture principles. Jotai, on the other hand, is a framework-agnostic state management library and can be used with any JavaScript framework or library, including React and Vue.
State Management Approach
@ngrx/store follows the traditional Redux pattern and relies on a centralized store, actions, and reducers to manage state. It provides tools like selectors and async actions to handle complex state management scenarios. Jotai, on the other hand, follows an atom-based approach inspired by Recoil. It allows developers to define and consume state atoms directly without the need for actions or reducers.
Developer Experience
Both packages provide a good developer experience. @ngrx/store has excellent TypeScript support and provides a rich set of devtools for debugging and time-traveling through state changes. It also has extensive documentation and a mature ecosystem. Jotai, as a newer library, has a simpler API with less boilerplate code required. It also provides good TypeScript support and has a growing community, but its ecosystem is not as extensive as @ngrx/store.
Performance
In terms of performance, both @ngrx/store and Jotai are designed to be efficient. However, @ngrx/store, being highly optimized for the Angular framework, has undergone more optimization and performance improvements over the years. Jotai, while performant, may have a slight performance advantage due to its simpler and more direct state management approach.
