MobX Quick Start Guide

By: Pavan Podila, Michel Weststrate

Overview of this book

MobX is a simple and highly scalable state management library in JavaScript. Its abstractions can help you manage state in small to extremely large applications. However, if you are just starting out, it is essential to have a guide that can help you take the first steps. This book aims to be that guide that will equip you with the skills needed to use MobX and effectively handle the state management aspects of your application. You will first learn about observables, actions, and reactions: the core concepts of MobX. To see how MobX really shines and simplifies state management, you'll work through some real-world use cases. Building on these core concepts and use cases, you will learn about advanced MobX, its APIs, and libraries that extend MobX. By the end of this book, you will not only have a solid conceptual understanding of MobX, but also practical experience. You will gain the confidence to tackle many of the common state management problems in your own projects.

Although there is a lean outer-level API for MobX, there is also a set of APIs for more fine-grained observation and mutation. We saw how the Object API can be used to make very surgical changes in your observable tree. With observe() and intercept(), you can track the changes happening in an observable and also intercept to modify the change.

spy() and trace() are your friends during debugging, and coupled with mobx-react-devtools, you have a visual debugger for identifying and improving render performance. These tools and utilities give you a rich Developer eXperience (DX) when working with MobX.

In Chapter 8Exploring mobx-utils and mobx-state-tree, we will raise the bar on using MobX with the special packages mobx-utils and mobx-state-tree.
