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.

Chapter 2. Testing

The general software development paradigm includes planning, analysis, design, implementation, and maintenance. During any software development process, it is challenging, but required, to build efficient and error-free software. Making software error-free requires rigorous inspection, testing, dry running, and debugging. Making any web application error-free is intractable. However, empirical studies have revealed that testing in web application development can sometimes be exhaustive. There are a multitude of JavaScript frameworks that can be used for unit testing. In this chapter, we will use Jest, which is a testing framework from Facebook.

The main topics that will be covered in this chapter are as follows:

  • Setting up Jest
  • Understanding how to test ES6 components
  • Exploring snapshot testing for React components
  • Testing Redux and its components
