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.

In this chapter, we applied a variety of techniques and concepts that we have learned over the last few chapters. Each of the two examples, form validation and page routing, presented a unique set of approaches for modeling the observable state. We also saw how to create granular observer components to enable efficient rendering of the React components.

A practical application of MobX always starts with modeling the observable state. After all, that is the data that drives the UI. The next step is to identify the actions that mutate the observables. Finally, you need to call out the side-effects and see which observables these effects depend on. This is the side effect model that's applied to real-world scenarios, manifesting in the form of the MobX triad: Observables-Actions-Reactions.

With all of the knowledge we have accumulated so far, we are now ready to go deeper into MobX, starting with Chapter 7Special API for Special Cases.
