Introduction to MobX with React

MobX, an open-source state management tool following functional reactive programming principles, provides developers with a simple and scalable solution for managing state in web applications. Unlike Flux or React-Redux, MobX operates independently of any frontend libraries or frameworks, yet it integrates seamlessly with popular options like React, Vue, and Angular. It centers around three core concepts: state, actions, and derivations, which include reactions and computed values. State represents the application's entire model, actions modify the state, and derivations automatically compute values based on the state without further interaction. The text demonstrates the practical application of MobX by creating a reactive store for managing pet owners and their pets, employing MobX's makeObservable function to enable the store's reactivity and ensuring that React components can respond to updates via the mobx-react-lite package. The article further explores how MobX enhances the development of a React application by implementing CRUD operations on the store, showcasing MobX's ability to manage data from a remote server, and concluding with a complete PetOwner React/MobX app.
