@harlem/core is a state management library for JavaScript applications, offering a simple and efficient way to manage application state. It provides a centralized store for managing data and state changes, using a reactive approach to update components when the state changes. @harlem/core is lightweight and easy to integrate into projects, offering features like actions, mutations, and getters for manipulating state.
@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.
@ngrx/store is widely used and highly popular in the Angular community. It has a strong following and is backed by the Angular team. On the other hand, @harlem/core is a relatively newer library and may not have the same level of popularity as @ngrx/store.
Functionality
@ngrx/store is a state management library specifically designed for Angular applications. It provides a powerful and comprehensive solution for managing application state using Redux principles. @harlem/core, on the other hand, is a lightweight state management library inspired by Redux, but without any Angular-specific dependencies. It offers a simpler and more minimalistic approach to state management.
Integration
@ngrx/store is tightly integrated with Angular and provides additional features like Angular DevTools and Angular Effects for managing side effects. It is the recommended state management solution for Angular applications. @harlem/core, on the other hand, can be used with any JavaScript or TypeScript application, including Angular, React, or Vue. It offers flexibility in terms of framework choice.
Developer Experience
@ngrx/store provides a well-defined and structured API that aligns with Angular's conventions, making it familiar for Angular developers. It has good TypeScript support, comprehensive documentation, and a large community for support and resources. @harlem/core also has a clean API and good TypeScript integration, but being a newer library, it may have a smaller community and fewer resources available.
Scalability
@ngrx/store is designed to handle complex and large-scale state management in Angular applications. It provides features like lazy loading of state modules, selectors, and middleware support, making it suitable for large and complex applications. @harlem/core, being a lightweight library, might be better suited for smaller or medium-sized applications with simpler state management requirements.
Ecosystem
@ngrx/store is part of the larger Angular ecosystem and integrates well with other Angular libraries and tools. It has established patterns and best practices for state management in Angular. @harlem/core, being framework-agnostic, may not have the same level of integration with other libraries and tools specific to Angular.
