Mobx-state-tree: An Opinionated, Transactional, MobX Powered State Container Combining the Best of Immutability and Mutability

A brief introduction to the project:

Mobx-state-tree or MST is an innovative project hosted on GitHub. Its primary aim is to provide an advanced state container combining the benefits of both mutability and immutability, allowing developers to manage application state effectively. MST, based on MobX, aims to facilitate the creation of complex applications by providing a clear separation of responsibilities and a straightforward way to manage dependencies.

Project Overview:

MST serves as an opinionated, transactional, and MobX-powered state container. It addresses the challenge of state management in large and complex applications, a task that often becomes complicated as the project grows. MST's target audience primarily encompasses developers working on complex applications that require a fine balance between mutability and immutability.

Project Features:

The central feature of MST is its ability to cater to the needs of both immutable and mutable data structures. Unlike traditional state containers, MST allows for safe, constrained mutability, enabling developers to modify data structures directly while still ensuring changes are propagated correctly. Another principal feature is its snapshot support, allowing developers to revert or recreate the entire tree state from a serialized version. MST also provides runtime type checking, ensuring invalid operations will cause exceptions, further increasing safety.

Technology Stack:

MST is built upon MobX, a battle-tested library that introduces reactive programming and makes state management simple and scalable. MST utilizes JavaScript as its primary language, expending the syntactic benefits of ES6 and beyond. The technology leverages various notable libraries such as lodash and Jest for testing.

Project Structure and Architecture:

MST follows a modular architecture where each tree in a state represents a module. Separating responsibilities among trees improves code organization, helps divide application state into decoupled, testable pieces, and boosts readability. MST employs the observer pattern extensively to ensure the propagation of state changes to the parts of the application that react to those changes.
