We’re working on a little project to skill-up together and, hey, it could definitely power a small application if you were keeping an eye on the size of your JavaScript payload. It’s also worth noting that I’m not saying that you should replace Redux or MobX with this. You should know about data types and ideally, you should have a grasp of some more modern ES6+ JavaScript features. How do these libraries work though? What would it take to write one ourselves? Turns out, it’s pretty straightforward and there’s an opportunity to learn some really common patterns and also learn about some useful modern APIs that are available to us.īefore we get started, it’s recommended that you have an intermediary knowledge of JavaScript. This is great for an application’s resilience and it works really well with a state-first, reactive framework such as React or Vue.
Libraries like Redux, MobX and Vuex make managing cross-component state almost trivial. Now though, we’re spoiled with choices for libraries and frameworks to help us with this. Traditionally, we’d keep state within the DOM itself or even assign it to a global object in the window. Managing state is not a new thing in software, but it’s still relatively new for building software in JavaScript.
