@ngxs/store is a state management library for Angular applications. It provides a simple and intuitive way to manage the state of your application by using a centralized store and reactive principles. With @ngxs/store, you can easily define and update the state of your application, and automatically trigger UI updates when the state changes.
Jotai is a state management library for React applications. It provides a simple and scalable solution for managing state in your components. Jotai follows the principles of atomic state and uses atoms as the fundamental building blocks. Atoms are units of state that can be read and updated independently, allowing for fine-grained control over your application's state.
Both @ngxs/store and jotai are popular npm packages, but they have different levels of popularity within their respective communities. @ngxs/store is a state management library specifically designed for Angular applications and has gained popularity among Angular developers. On the other hand, jotai is a relatively new state management library for React and may not be as widely known or adopted as @ngxs/store.
Both libraries offer scalability, but in different ways. @ngxs/store is designed with larger enterprise-scale applications in mind and provides built-in features like actions, selectors, and plugins that can handle complex state management requirements. jotai, on the other hand, takes a different approach and focuses on a lightweight and flexible API that can be scaled efficiently and used in smaller to medium-sized applications.
The developer experience with @ngxs/store and jotai varies based on the framework or library they are built for. @ngxs/store is tightly integrated with Angular, leveraging its concepts and providing Angular-specific features like dependency injection and decorators. This can be beneficial for Angular developers who are already familiar with those concepts. jotai, on the other hand, is built for React and follows React's hooks-based approach, providing a more intuitive and simpler API for React developers.
Both @ngxs/store and jotai aim to provide good performance, but their implementations differ. @ngxs/store uses Angular's change detection mechanism and provides an optimized immutable state handling through the concept of actions and direct state mutation. jotai is built on top of React's primitives and leverages the React's virtual DOM diffing algorithm, allowing it to efficiently update the necessary parts of the UI when the state changes. In general, both libraries have good performance characteristics, but the specific performance characteristics may vary based on the complexity of the application and the usage patterns.
Community and Ecosystem
The community and ecosystem around @ngxs/store and jotai also differ. @ngxs/store has been around for a longer time and has a larger community, which means there is a wealth of documentation, tutorials, and community support available. It also has a wide range of plugins and extensions developed by the community. jotai, being a relatively newer library, may not have an extensive ecosystem or as many resources available, but it is backed by the React community, which is known for its vibrant ecosystem, and is likely to grow and evolve over time.
