This book explores methodologies for developing a scalable, modern web application using cutting-edge, frontend technologies. It is intended for web developers, frontend developers, and novice programmers who want to use React and Redux to develop a modern web application. In this book, we will show you how you can integrate Redux with React and other frontend JavaScript frameworks efficiently, and manage application states effectively. Finally, we will explore the architecture of Redux Saga and see how Saga can be used in handling side effects.

We will follow the TDD (test-driven development) paradigm in this book, where we test each piece of code we develop. We will use the JEST framework for testing. In addition to this, we will learn about advanced debugging techniques using Redux Dev tools. In this book, we will build a simple, multilingual hospital management system to perform CRUD (Create, Read, Update, and Delete) on users. We will use React to build interactive user interfaces, and we will utilize Redux Form and Ant Design to exploit user interfaces to meet our needs. Finally, we will explore using styled-components to include CSS in our application.

To develop a scalable web application, the project architecture, correct tooling, and utilization of the correct stack is very important. With numerous options, developers easily get confused about the choice of database, the choice of frontend technologies, which type of module bundler to use, and so on. In this book, we will guide users through a single application architecture paradigm using cutting edge technology, including ReactJS with Redux for state management, and Redux Saga for handling side effects.
