REACT, REDUX AND JAVASCRIPT ARCHITECTURE

The content of this article was originally presented to the Squiz Front-End Engineering group.

Whether you use them or not, React and Redux are important. They have changed the way we think about structuring front-end web applications. They can be very powerful. But they are not magic. JavaScript code does not automatically become better just because it uses React. It is easy to write horrible React code, just like it’s easy to write horrible vanilla JavaScript. So, why is React important then? The thing is, understanding how to write React and Redux code is one thing. Understanding why you’d want to use React and Redux is another matter entirely. Once you understand the why of React and Redux, then modern JavaScript starts to make more sense. This is true whatever framework you’re using. Whether it’s React, Vue, Ember, Angular, Web Components, or something else entirely. React and Redux have had a huge impact on how we organise front-end code.1

So, this article might seem long-winded. I do want to show you how to write actual React and Redux code. But it will take a while to get there. And there is a reason. Redux is not terribly complicated. But with Redux (like React), understanding why you’d want to use it is much more interesting than how it works. So, though it might take us a little while to get to Redux, I think the journey will be worth it.
