Vue Axios Tutorial by Example (CRUD API)

Vue Axios Tutorial by Example (CRUD API)

In this Vue Axios tutorial we'll learn to use Axios (an http client) by example sending post, get, put and delete requests to a REST API. We'll see how to add CRUD (Create, Read, Update and Delete) methods with a Vue.js front-end and a Python Django RESTful API back-end.

Axios is a promise-based modern http client library that runs on the browser and the server through Node.js. Axios works asynchronously and allows you to make HTTP calls to REST endpoints and consume REST APIs.

Using Axios with Vue

We'll use Axios to send API or HTTP calls (We'll write code for sending GET, POST, DELETE and PUT HTTP requests.) from a Vue.js interface to a RESTful API back-end built with Django.

First things first, let's get the back-end code.

Getting the Django Example Back-End

In this tutorial, we'll be focusing on building the Vue.js and Axios front-end so we'll be using a previously built Django API available from this GitHub repository

Using the following command, you can clone the back-end code:

$ git clone
$ cd django-crm

Next, you need to create a virtual environment and install packages using pipenv:

$ pipenv install

Next, activate the virtual environment using:

$ pipenv shell 

Finally, create and migrate the database and run the local development server using:

$ python migrate
$ python runserver

You server will be running from http://localhost:8000. You are now ready to create the Vue.js interface to communicate with the back-end using the Axios HTTP client.

Creating the Vue Front-End

Navigate inside your project and create a front-end project using the Vue CLI we've installed on the previous tutorial.

$ vue create frontend

That's it! You now have a Vue project ready.

You can serve your application using the following command:

$ vue serve

Installing Axios Http Client

The next step is to install Axios in your Vue project using the following command:

$ npm install --save axios

Consuming The RESTful API Using Axios

After installing Axios, we'll use it to consume to RESTful API exposed from http://localhost:8000.

To encapsulate all the code interfacing with REST API server we'll create a JavaScript class inside the frontend project and we'll add different methods to send API calls such as POST, GET, PUT and DELETE.

Go ahead and create APIService.js inside the frontend/src folder:

cd frontend/src
touch APIService.js

Next open APIService.js using your favorite code editor and add the following code to create the APIService class:

import axios from 'axios';
const API_URL = 'http://localhost:8000';
export class APIService{



We've imported axios, defined an API_URL variable which holds the address of the REST API server and then declared and exported the APIService class with a constructor.

We have different REST endpoints such as /api/accounts and /api/contacts etc. Let's see an example with the /api/contacts endpoint:

Vue and Axios GET Example

Let's start by getting the list of contacts using an HTTP GET request. Add the following code to the APIService.js:

getContacts() {
    const url = `${API_URL}/api/contacts/`;
    return axios.get(url).then(response =>;

We declared a getContacts() method which makes a GET call, using the axios.get() method, to the /api/contacts endpoint. We are taking the data part from the response and then returning a Promise, from the function, which would resolve to an array of contacts or an error.

We also need a method to get single contacts by id or primary key. Let's add a second method to APIService.js:

getContact(pk) {
    const url = `${API_URL}/api/contacts/${pk}`;
    return axios.get(url).then(response =>;

In the same way, the method returns a Promise which would resolve to a single contact or error.

Example Using Http GET Calls

After adding the two methods for sending GET requests to the API server, we can now call them from any Vue component.

First create a Vue components for displaying contacts. Navigate inside frontend/src/components then run the following command:

touch ListContacts.js

Open the ListContacts.js file and start by adding a template:

<h1>Contacts ()</h1>

<table class="table table-bordered table-hover">




<th>First Name</th>
<th>Last Name</th>
<th> Address </th>
<tr v-for="contact in contacts">

<th>{ { } }</th>

<th>{ { contact.first_name } }</th>

<td>{ { contact.last_name } }</td>

<td>{ { } } </td>

<td>{ { } }</td>

<td>{ { contact.address } }</td>


<button class="btn btn-danger" @click="deleteContact(contact)"> X</button>


We use the v-for directive to loop through the contacts array and display information about each contact in a HTML table.

Next, in the same file add the following JavaScript code:

import {APIService} from '../APIService';

const API_URL = 'http://localhost:8000';
const apiService = new APIService();

export default {

name: 'ListContacts',

components: {


data() {

return {
contacts: [],



methods: {

    apiService.getContacts().then((data) => {

        this.contacts =;
        this.numberOfContacts= data.count;

mounted() {

We first declare a contacts and numberOfContacts variables in the data() method of our Vue component. Next, we add a getContacts() method which call the getContacts() of the APIService instance we created in the start of the file. When the promise resolves we assign the results to our declared variables i.e contacts and numberOfContacts. In the mounted() method of the component we call the getContacts() method so we can get contacts to display as soon as the component is mounted.

Vue and Axios Post Example

Let's now see how we can post data to our RESTful API server by sending an http POST call using Axios. Add the following method to the APIService.js class:


    const url = `${API_URL}/api/contacts/`;

We declared a function createContact() which takes a contact object and send it via a POST request using method. The function returns a Promise which can be resolved to success or error response.

Vue and Axios Put Example

After implementing the http POST method , let's see the code for making an http PUT method which can be used to update data. In the APIService.js class add the following method:


    const url = `${API_URL}/api/contacts/${}`;
    return axios.put(url,contact);

The updateContact() method makes a PUT call to the API server by using the axios.put() method.

Vue and Axios Delete Example

Let's see how to add a method for deleting contacts. In the APIService.js class, add the following method:

    const url = `${API_URL}/api/contacts/${}`;
    return axios.delete(url);

The deleteContact() use the axios.delete() method to send a DELETE request to the API server.


In this tutorial with Vue and Axios, we've seen how to implement CRUD (Create, Read, Update and Delete) functionality using the Axios http client with Vue.js and a REST API server.
