This command will show some setup steps which we want to leave as it is. Let's initialize and create a package.json file for our app: npm init

Now add the folder to the workspace, and open your terminal. For this tutorial, I'll call mine node-babel. Let's setup a basic Node app which we will use for this tutorial.Ĭreate a new folder. This tutorial assumes that that you have the following: So in this tutorial, I'll show you how to quickly setup your Node app to be compatible with most ES6 syntax.Īwesome right? Let's dive in. And many frameworks today use Babel under the hood to compile their code.įor example, Node can't use ES6 import and export statements and some other cool features of ES6 syntax without the help of a compiler like Babel. Remember that Babel is a popular tool that lets you use the newest features of JavaScript. Have you ever opened a back end repo built with Node.js/Express – and the very first thing you saw was the ES6 import and export statements along with some other cool ES6 syntax features? It's a popular tool that helps you use the newest features of the JavaScript programming language. What is Babel?īabel is a JavaScript compiler. To help you learn how to use it effectively, in this article we will create a simple server using Node with Babel configured in our code.īut before we take a deep dive into building out our server, let's learn more about what Babel is.
