Last Updated :

Many times when building an application for the web that you may want to consume and display data from an API in VueJS using JavaScript fetch API, Vue resource, jquery ajax API, but a very popular and most recommended approach is to use Axios, a promise-based HTTP client.
Axios is a great HTTP client library. Similar to JavaScript fetch API, it uses Promises by default. It’s also quite easy to use with VueJS.
Creating VueJS Application and Installing Module:
-
Step 1: Create a Vue application using the following command.
vue create vue-app
-
Step 2: Install the Axios module using the following command.
npm install axios
-
Step 3: We can include Vue.js into HTML using the following CDN link:
<script src=”https://cdn.jsdelivr.net/npm/vue@2.5.17/dist/vue.js”></script>
Project Directory: It will look like this.
Project structure
index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script src=
</script>
<script src=
</script>
<link rel="stylesheet" href="css/style.css">
</head>
<body>
<div id="app-vue">
<div class="users">
<div v-if="errored">
<p>
We're sorry, we're not able to
retrieve this information at the
moment, please try back later
</p>
</div>
<div v-else>
<h4 v-if="loading">
Loading...
</h4>
<div v-for="post in posts"
:key="post" class="post">
{{post.title}}
</div>
</div>
</div>
</div>
<script>
new Vue({
el: '#app-vue',
data() {
return {
posts: null,
loading: false,
errored: false
}
},
created() {
// Creating loader
this.loading = true;
this.posts = null
axios.get(
.then(response => {
// JSON responses are
// automatically parsed
this.posts = response.data
})
// Dealing with errors
.catch(error => {
console.log(error)
this.errored = true
})
}
});
</script>
</body>
</html>

style.css
#app-vue {
display: flex;
justify-content: center;
font-family: 'Karla', sans-serif;
font-size: 20px;
}
.post {
width: 300px;
border: 1px solid black;
display: flex;
flex-direction: row;
padding: 20px;
background: #FFEEE4;
margin: 10px;
}

Steps to Run Application: If you have installed the Vue app, you can run your application using this command.
npm run serve
Output: If you are using it as CDN then copy the path of your HTML and paste it on your browser.

Conclusion: There are many ways to work with Vue and axios beyond consuming and displaying an API. You can also communicate with Serverless Functions, post/edit/delete from an API where you have to write access, and many other benefits.
