Fight!

Popularity

mobx-state-tree is a popular state management library within the React ecosystem, known for its simplicity and robustness. It has a large community following and is widely used in production. @harlem/core, on the other hand, is a relatively newer library and may not have as much recognition and adoption at the moment.

Architecture

mobx-state-tree is built on top of MobX, providing a structured and opinionated way to manage application state using a tree-like data structure. It enforces a strict separation between state and logic, allowing for easy modeling of complex application states. @harlem/core takes a similar approach but integrates seamlessly with Redux. It provides a simple and intuitive way to manage global state using Redux principles while leveraging React hooks.

Developer Experience

mobx-state-tree provides a rich developer experience with tools like snapshot testing, time-travel debugging, and TypeScript support out of the box. It has a well-documented API and a comprehensive set of features, making it easy to work with and debug application state. @harlem/core focuses on simplicity and ease of use, providing a minimalistic API that fits well within the Redux ecosystem. It also has TypeScript support and clear documentation, offering a smooth development experience.

Performance

mobx-state-tree leverages MobX's reactivity system, which is highly optimized and can efficiently update only the necessary parts of the state. This results in excellent performance, especially for large and complex state trees. @harlem/core also provides efficient updates by utilizing Redux's immutable update patterns. While the performance of both libraries is generally good, the specific use case and complexity of the state can influence the performance characteristics.

Integration

mobx-state-tree is primarily designed to work with MobX and React, providing seamless integration and extensive support for observables, actions, and reactions. It has a mature ecosystem and works well with other MobX-related libraries. @harlem/core, on the other hand, is built on top of Redux and integrates smoothly into Redux workflows. It's compatible with existing Redux middleware, tools, and patterns, making it a suitable choice for projects already using Redux or requiring interoperability with Redux ecosystem.

Community Support

mobx-state-tree has a large and active community with regular updates, extensive documentation, and a wide range of community-driven packages and extensions available. It benefits from being part of the MobX ecosystem, which adds to its popularity and support. @harlem/core is relatively new, and while it may not have the same level of community support as mobx-state-tree, it is actively maintained and has gained some traction within the React and Redux community.
