In Detail

APIs are at the core of every serious web application. Express.js is the most popular framework for building on top of Node.js, an exciting tool that is easy to use and allows you to build APIs and develop your backend in JavaScript. Express.js Blueprints consists of many well-crafted tutorials that will teach you how to build robust APIs using Express.js.

The book covers various different types of applications, each with a diverse set of challenges. You will start with the basics such as hosting static content and user authentication and work your way up to creating real-time, multiplayer online games using a combination of HTTP and Socket.IO. Next, you'll learn the principles of SOA in Node.js and see them used to build a pairing as a service. If that's not enough, we'll build a CRUD backend to post links and upvote with Koa.js!
