How to fetch JSON data using Vue.js and Axios

In this tutorial, you’ll learn how to quickly fetch remote JSON data in Vue.js.

This approach works for both single page Vue.js applications and Vue.js added to existing project.

First let’s initialize a Vue.js app. In this example we’ll be adding Vue.js to the existing project e.g. WordPress site.

We’ve just loaded Vue.js and Axios library from the CDN.

Now we need to add a <div class="app"></div> to the DOM. This will render Vue.js data inside that div.

The final part is to actually fetch the remote JSON data using Axios. I’ll be using dummy REST API {JSON} Placeholder. See the code below.

var app = new Vue({
  el: "#app",
  data: {
    url: 'https://jsonplaceholder.typicode.com/todos/',
    todos: []
  },
  mounted() {
    axios.get(this.url).then((response) => {
      this.todos = response.data
    })
  }
});

That’s it. We’ve just downloaded our first JSON list. It’s a list of todos. If you want to render, you can do that by adding a moustache code to the DOM like so:

<div id="app">
  <pre>{{ todos }}</pre>
</div>
