Redux Quick Start Guide

By: James Lee, Tao Wei, Suresh Kumar Mukhiya

Overview of this book

Starting with a detailed overview of Redux, we will follow the test-driven development (TDD) approach to develop single-page applications. We will set up JEST for testing and use JEST to test React, Redux, Redux-Sage, Reducers, and other components. We will then add important middleware and set up immutableJS in our application. We will use common data structures such as Map, List, Set, and OrderedList from the immutableJS framework. We will then add user interfaces using ReactJS, Redux-Form, and Ant Design. We will explore the use of react-router-dom and its functions. We will create a list of routes that we will need in order to create our application, and explore routing on the server site and create the required routes for our application. We will then debug our application and integrate Redux Dev tools. We will then set up our API server and create the API required for our application. We will dive into a modern approach to structuring our server site components in terms of Model, Controller, Helper functions, and utilities functions. We will explore the use of NodeJS with Express to build the REST API components. Finally, we will venture into the possibilities of extending the application for further research, including deployment and optimization.

The need for immutability

The home page for immutable JS briefs the merits of using the library. However, it is a bit difficult to understand. In this section, we will explain the importance of immutable JS in simple terms. The use of Immutable JS is a hot topic of discussion in the frontend community. A couple of important aspects of immutability are that it increases predictability and performance and allows for mutation tracking. In addition to that, immutable JS provides a convenient way to modify deeply nested properties.

The data reference problem

A lot of bloggers and developers seem to accuse Immutable JS of certain things, without understanding its core concepts. React is not just about building interactive UI/UX interfaces; it is about performance. The purpose of its development was to be performant and to only update the DOM when required, and also, to only update the portion that was required to be updated. An optimized React app should contain simple, stateless functional components...
