Summary

Node.js 10 has entered the LTS era! Its use cases have expanded from scaffolding and auxiliary front-end development (such as SSR and PWA) to API middleware layers, proxy layers, and professional back-end development. Node.js is also maturing in enterprise web development, with solid adoption in both API middleware and microservices. This book uses the web development framework Koa2 to guide you into the main arena of Node.js! This book systematically explains the processes and steps for developing web applications with the Koa framework in real-world projects. Chapter 1 covers Node.js installation, development tools, and debugging. Chapters 2 and 3 introduce the prototype of a Koa real-world project. Chapter 4 details HTTP fundamentals and their practical applications. Chapter 5 covers practical features such as MVC, template engines, and file uploads. Chapters 6–8 cover databases, unit testing, and project optimization and deployment. Chapters 9–13 walk through the entire process of building, from scratch, the front end and back-end management application of a WeChat Mini Program—currently all the rage—as well as final server deployment, including HTTPS and Nginx. This book offers abundant examples and emphasizes hands-on practice, with a complete real-world project running through every chapter. It provides all source code covered in the book and companion video tutorials for selected chapters, making it a capable assistant for front-end developers entering a new field and for back-end developers learning about Node.js and using Koa2 to develop web applications.

Editor's review

Published by Publishing House of Electronics Industry in 2019, Koa and Node.js Development in Action is a hands-on web development book. Its author team, iKcamp, consists of experienced front-end developers with a notable presence in the Node.js community. Centered on Koa2, a lightweight and efficient Node.js framework, the book systematically covers the complete development process from fundamentals to enterprise-level applications. According to reader feedback on platforms such as Douban, the book is detailed and its examples are close to real-world practice, making it especially suitable for readers who wish to move from frameworks such as Express to Koa or to systematically learn modern Node.js back-end development. Its value lies in its clear structure and progressive difficulty: it not only explains core concepts such as middleware, routing, and template engines, but also explores engineering topics including error handling, performance optimization, security protection, and testing, and provides a complete project case study. For developers with some JavaScript background who want to build high-performance, maintainable Node.js services, this is an excellent practical guide. Note that technical books age quickly, so readers should consult the latest official Koa and Node.js documentation while reading.

Who it's for

A good fit for

JavaScript-savvy beginners who want to systematically learn Node.js backend development
Developers with experience in frameworks like Express who want to move to the more modern, lightweight Koa framework
Learners who need a clearly structured, case-complete hands-on handbook to build full Node.js projects
Technologists interested in asynchronous programming, middleware mechanisms, and RESTful API design in web development

Not a good fit for

Absolute beginners with no programming background who have not yet mastered basic JavaScript syntax
Senior developers seeking cutting-edge Node.js features (such as the latest ES module support) or in-depth source code analysis

Reading tips

Read in chapter order: first solidify core Koa concepts (such as Context and the middleware onion model), then move on to the hands-on sections
Hands-on practice with the code examples and project cases is key to understanding; try extending or modifying features on your own after grasping them
Combine the book with official documentation and community resources, and keep up with the latest developments in Koa and related ecosystem libraries (such as koa-router, koa-bodyparser)

FAQ

What prior knowledge does this book require of readers?

You need basic JavaScript (ES6+) syntax and concepts of asynchronous programming (Promise, async/await); a preliminary understanding of HTTP protocol and web development will make it easier to get started.

Are the cases and tech stack in the book outdated?

The book is based on Koa2 and stable Node.js versions of the time; core concepts (middleware, asynchronous flow control) still apply. Some dependency versions may be older, so consult the latest official documentation for version adjustments when practicing.

What are the main features of this book compared with books on Express?

This book focuses on the Koa framework, which is lighter and makes fuller use of ES6+ asynchronous features (such as async/await). It offers deeper discussion of middleware mechanisms, error-handling practices, and future-oriented asynchronous programming paradigms, suiting developers who want a more modern tech stack.
