One of the things that makes Koa so desirable to work with is the ease of getting started with it. Taking after Express, all of the logic for a simple web application can be contained in a single JavaScript file with Koa. This works to our benefit and is especially great if you are just willing to test the framework out before taking a deep dive.
In this chapter, we are going to get our hands dirty and get into the code. We will be exploring the basic concepts of Koa and will build our first server-side application in Koa.
Some of the topics we will cover in this chapter include the following:
- Modern JavaScript
- A primer on Node
- What is async… await?
- Using Babel
- Installing Koa
- Starting a server in Koa
