Overview of this book

<p>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.</p> <p>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!</p>

Chapter 6. Hacker News API on Koa.js

In this chapter, we will build an API to power our own Hacker News! While technically this wouldn't be very different from the previous chapters, we will use a different framework altogether, Koa.js (http://koajs.com/).

Koa.js is a new web framework designed by the team behind Express. Why did they create a new framework? Because it is designed from the bottom up, with a minimalistic core for more modularity, and to make use of the new generator syntax, proposed in ECMAScript 6, but already implemented in node 0.11.

Note

The odd version releases of node are considered unstable. At the time of writing, the latest stable release was version 0.10. However, when this book went to print, node 0.12 was finally released and is the latest stable version.

An alternative to node 0.11 would be io.js, which at the time of writing reached version 1.0, and also implements ES6 goodies (forked from Node.js and maintained by a handful of node core contributors). In this chapter...
