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.

mobx and mobx-react are two NPM packages that are used extensively to build the Reactive UI. The mobx package provides the API to build the observable state, actions, and reactions. On the other hand, mobx-react gives the binding glue to connect the React components to the observable state and also react to any changes. In our example, we made use of these APIs to build a book search app. When creating your observer-driven component tree, make sure to go granular with the use of observers. This way you will react to just the observables you need to render the UI.

The SearchTextField, SearchStatus, and ResultsList components were created with the intent of being granular and reacting to a focused observable surface. This is the recommended way to use MobX with React.

In the next chapter we will dive deeper into MobX, with an exploration of the Observables.
