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.

Chapter 9. Mobx Internals

The MobX we have seen so far was from a consumer's standpoint, which focused on how it should be used, the best practices, and the APIs for tackling real-world use cases. This chapter takes it a level below and exposes the machinery behind the MobX reactive system. We will look at the underpinnings and the core abstractions that makes the triad of Observables-Actions-Reactions come to life.

The topics that will be covered in this chapter include the following:

  • The layered architecture of MobX
  • Atoms and ObservableValues
  • Derivations and reactions
  • What is Transparent Functional Reactive Programming?
