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.

Direct manipulation with the object API

When deciding on the data structures for your observable state, your natural choice should be to reach out for observable.object(), observable.array(),, or to use the convenient observable() API. Manipulating these data structures is as simple as mutating the properties directly or adding and removing elements as needed.

MobX gives you yet another way to surgically make changes to your data structures. It exposes a granular object API that can mutate these data structures at runtime. In fact, it gives you some capabilities that are not even possible with the original data structures. For example, adding new properties to observable objects and also keeping it reactive.  

Granular reads and writes

The object API is focused on giving you granular control over the observable properties of top-level data structures: objects, arrays, and maps. In doing so, they continue to play well with the MobX reactive system and ensure...
