It is often a false assumption that MobX can only be used with decorators. That's not true. The article explains how to use MobX in a create-react-app or Next.js application with and without using decorators. There is also one alternative to avoid ejecting when using create-react-app.
The course turned out to exceed all my expectations. What started as an attempt to write a sole book about state management in React with Redux and MobX, turned out into a full blown course with a 250-page book, exciting applications and boilerplate projects to get started in learning and building applications with these libraries, and screencast series about implementing React applications from scratch with state management.
Everyone wants to have state management in an application. But what problem does it solve for us? Most people start with a small application and already introduce a state management library. Everyone is speaking about it, aren't they? But most applications don't need ambitious state management from the beginning. It is even more dangerous, because most people are never going to experience which problems libraries like Redux or MobX solve.
The MobX React: Refactor your application from Redux to MobX tutorial will teach you how to use MobX instead of Redux for state management in React. We will come from a Redux + React seed project and refactor it from Redux to MobX. While we do so, I will explain in detail the concepts behind MobX and the similarities and differences compared to Redux.
