Preface

UmiJS is a scalable JavaScript framework for building enterprise-level frontend applications. Umi uses React and is based on a routing system that allows you to make fast and responsive applications.

In this book, we will build a frontend web application for a customer relationship management (CRM) system. Starting with your environment setup, I will introduce you to the main features of UmiJS and how a project is structured. After that, we will explore Ant Design, a design system with a vast library of React components for quickly building modern and responsive user interfaces that deeply integrate with Umi.

You will also learn an approach based on models and services to handle HTTP requests and responses and control an application's state in complex scenarios.

After learning to work with Umi, you will explore how to improve code quality by implementing a consistent code style and using formatting tools such as Prettier and EditorConfig. You will also learn how to design and implement tests for frontend applications.

Finally, you will host your CRM frontend application on AWS Amplify, an out-of-the-box platform for frontend developers to build full-stack applications using several AWS services.
