@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.

Effector is a state management library for JavaScript applications, focusing on predictable state management and efficient event handling. It provides a declarative way to define and update application state, making it easier to manage complex data flows and interactions. Effector offers features like stores, events, effects, and combinators to handle state changes and side effects in a clear and concise manner.

Fight!

Popularity

Both @ngrx/store and effector are popular state management libraries in the JavaScript ecosystem. However, @ngrx/store, which is primarily used with Angular applications, has a larger and more established community compared to effector, which is a newer library.

Scalability

@ngrx/store is specifically designed for large-scale applications with complex state management needs. It provides built-in support for features like lazy loading, code splitting, and time-travel debugging. Effector also offers good scalability with a lightweight and performant design, but it may require more manual configuration for larger projects.

Performance

Both @ngrx/store and effector are optimized for performance. However, effector is known for its highly efficient and predictable performance due to its advanced algorithms for dependency tracking and memoization. @ngrx/store is also performant but may require additional optimizations for more complex scenarios.

Developer Experience

Both libraries offer a good developer experience. @ngrx/store integrates seamlessly with Angular applications and follows Angular conventions. It provides strong TypeScript support, well-documented API, and a rich set of tools for debugging and testing. Effector, on the other hand, offers a more functional and composable approach to state management with a clean and intuitive API. It also provides good TypeScript support and has well-maintained documentation.

Community and Ecosystem

Although effector has gained popularity and has an active community, @ngrx/store benefits from the vast Angular community and has a larger ecosystem of libraries and tools that work well together with Angular. @ngrx/store also has strong community support, extensive resources, and a mature ecosystem.

Learning Curve

Both libraries have a learning curve, but @ngrx/store may have a steeper learning curve for developers who are not familiar with Angular concepts and conventions. Effector, with its functional programming approach, may be easier to grasp for developers already familiar with functional programming concepts.
