@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.
@ngrx/store follows a more opinionated approach with a rigid structure and guidelines, which can provide a consistent development experience in Angular projects. Overmind, on the other hand, prioritizes developer ergonomics and offers a more flexible and intuitive API, making it easier to work with, especially for developers who prefer a more expressive and customizable approach to state management.
Both libraries are performant and optimized for efficient state management. @ngrx/store utilizes the principles of reactive programming and leverages the power of RxJS observables. Overmind, on the other hand, focuses on minimal re-renders and state mutation tracking for optimal performance. The choice between them largely depends on the specific requirements and preferences of the project.
Community and Ecosystem
@ngrx/store has a strong and active community within the Angular ecosystem, with extensive resources, documentation, and third-party plugins available specifically for Angular projects. Overmind has a smaller but growing community with a focus on React and Vue ecosystems. Both libraries have dedicated Slack communities and provide support through GitHub issues.
