Too Long; Didn't Read Immutable data structures are a great paradigm for storing state. But in a language like JavaScript, producing a new state from the previous one is a boring, boiler-platy task. Introducing Immer: Immutability the easy way to use persistent data structures in ReactJS. Immer works by writing producers, and the simplest producer possible looks like this: const nextState = produc
Introduction If youâre developing React applications, then you know that the React community has been bursting with new ideas and tools over the last year. When investigating any new technology to incorporate into a stack, we should consider if it either makes the workflow much easier, or solves a key problem. MobX and Enzyme are 2 new libraries in the React world that fit the bill. This sample to

When youâre building a web application, you have to handle forms to get input from your users. Unfortunately, forms in React are not that straightforward at the beginning; especially if you are used to a full featured-framework like Angular.js â and Iâve seen people asking about handling react forms with Mobx multiple times. In this post, I am going to explain a simple approach to handle React for
Due to popular demand (and to have a cool story for my grand-children), these are the inner workings of MobX. A lot of people are surprised how consistent and fast MobX is. But rest assured, there is no magic in play! First, letâs define the core concepts of MobX: Observable state. Any value that can be mutated and might serve as source for computed values is state. MobX can make most types of val
