MobX Quick Start Guide: Supercharge the client state in your React apps with MobX

Apply functional Reactive programming for simple and scalable state management with MobX

Key Features

• The easiest way to learn MobX to enhance your client-side state-management
• Understand how the concepts and components fit together
• Work through different state management scenarios with MobX

Book Description

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.

What you will learn

• Explore the fundamental concepts of MobX, such as observables, actions, and reactions
• Use observables to track state and react to its changes with validations and visual feedback (via React Components)
• Create a MobX observable from different data types
• Define form data as an observable state and tackle sync and async form validations
• Use the special APIs to directly manipulate observables, tracking its changes, and discovering the reasons behind a change
• Tackle any state management issue you may have in your app by combining mobx-utils and mobx-state-tree
• Explore the internals of the MobX reactive system by diving into its inner workings
