Getting Started With Redux

Getting Started With Redux

By far the most popular, at least for React, is a library called Redux. Redux separates your app’s internal state to a central location outside of the component tree.

If you’ve ever worked with React, you know managing state is central to building interesting apps. But if you’ve ever built anything with complex state in React, you know it can get hectic quickly — different components need different information, and passing props and callbacks from parent components becomes a debugging nightmare, as you sit in front of your illegible mess of code, weeping.

That last part might not be universal, but the fact is tracing the threads of application state across components is messy, inefficient, and stressful.

Fortunately, as you’ve probably guessed, other, smarter people had this problem before me, and came up with tools to simplify it. By far the most popular, at least for React, is a library called Redux. Redux separates your app’s internal state to a central location outside of the component tree. This saves you from having to pass information down from parent components to child components, and makes that information equally accessible from everywhere. It also helps keep your applications predictable, and offers useful tools for debugging.

I’m going to break down Redux piece by piece. This post will cover the most basic pillars of Redux, and set a foundation for moving forward. In the future, I’ll dive into more advanced parts, but in the interest of keeping this short, I decided to break it up.
