MobX

MobX is a state management library that makes application state reactive through transparent functional reactive programming. It automatically tracks state dependencies and updates components when observable data changes. The library uses decorators and observable objects for minimal boilerplate code. MobX provides computed values that derive from state and automatically update. It integrates with React, Vue, and other frameworks through bindings. The library focuses on simplicity and performance with fine-grained reactivity. MobX is popular in applications requiring straightforward state management without complex patterns.
