Vue.js is quickly becoming a very popular option as a library for reactive components. It’s lightweight, simple to grasp and fun to play with, and it can prove to be a great alternative to other libraries like React or Angular.

Let’s get our feet wet with the simplest of examples. Here’s the code for our basic Hello World app, with the interesting parts highlighted:

<!DOCTYPE html>
<html lang="en">
  <meta>
    <meta charset="UTF-8">
    <title>Hello World in Vue.js</title>
  </meta>

  <body>
	
    <div id="hello-world-app">
      <h1>{{ msg }}</h1>
    </div>

    <script
      src="//cdnjs.cloudflare.com/ajax/libs/vue/2.1.6/vue.min.js">
    </script>

    <script>
      new Vue({
        el: "#hello-world-app",
        data() {
          return {
            msg: "Hello World!"
          }
        }
      });
    </script>

  </body>
</html>

Step by step breakdown:

  • First we have a basic HTML boilerplate file.
  • A div with an id of #hello-world-app will contain our app.
  • In the div, we have an h1 and a reference to an msg piece of data.
  • We call for the minified Vue.js library that’s hosted on cdnjs. 2.1.6 is the latest version as of this writing.
  • We then instantiate a new Vue object and tell it with el that our app is the #hello-world-app div.
  • Finally, we provide the data needed with the data object. In this case, we provide the data for msg.

And that’s it for this brief introduction! Learn more by reading the getting started section of the official Vue.js guide.
