How to build a Vue.js app with Django REST framework

11 min read 3171

Most applications are driven by web APIs, which hold data that other applications can access and manipulate to fit their demands. This API will only be meaningful to the users if your application has interfaces that let them interact with the raw API data.

Creating such modern web applications calls for modern web solutions. In this article, we will discuss how to create an API in Django and set up a Vue.js interface to consume it. We will build a handy full stack “to-do” app that uses a Django-based API and interactive Vue interfaces. This will hopefully teach you many of the critical concepts of full-stack web programming.

To follow along with this tutorial, it is necessary to have the following:

  • Working knowledge of writing and running Python scripts
  • Working knowledge of JavaScript
  • Python and Node.js installed and ready to use
  • Postman installed on your computer

Why Vue.js and Django REST framework?

Vue is one of the most popular JavaScript frontend frameworks. It helps create interfaces and can process API data. Some of the reasons for choosing to work with Vue include the following:

First is application reactivity, which allows you to automatically adjust to changes and update the user interface. Vue allows focusing on your page’s components that you want to be reactive. This way, it knows precisely which components need to be re-rendered when a state changes. Instead of re-rendering the whole page component.

Next is scalability and flexibility. Vue is suitable for all project sizes, from small side projects to a large enterprise-level app. It gives you the ability to scale up incrementally, then progressively add in the tools and features that you need to build.

Finally, there’s component reusability. This allows you to create components that are injected anywhere into multiple sections pages.

Django is a Python-based framework for building web applications. Django REST framework works on top of Django. It is a library we can use to build web-based APIs quickly and efficiently with minimal code.

Setting up a Django project

While setting up this Django project, we will use a virtual environment. The virtual environment helps to separate different Python environments for different projects. Let’s say you have multiple projects that rely on a single package, such as Django. Each project may be using a different version of Django, so if you upgrade that package, it can break the codebase of your project.

The virtual environment helps you isolate environments for each project. This way, each project will run only the dependencies, packages, and the specific versions they need.

Go ahead and create a project folder where you want your Django project to live. Open a terminal that points to the created directory. Then create a virtual environment using the following command:

python3 -m venv django_rest_api

Once the process is done, cd to the created django_rest_api directory:

cd django_rest_api

Now, activate the virtual environment. If you are on Windows, use command django_rest_api/Scripts/activate, or source django_rest_api/bin/activate if you are on Linux or MacOS.

Once that is set, go ahead and install Django to your environment:

python -m pip install django

Now we can initialize and start the Django REST project:

django-admin startproject django_rest_api_tasks

This will result in the creation of a new directory with the following file structure:

  • django_rest_api_tasks, a top level project folder
  • django_rest_api_tasks/django_rest_api_tasks, a lower level project folder for managing apps
  •, the command center file for your project

The next step is to start an app. Django has “projects” and “apps,” which are slightly different from each other. A project is a high level unit that encapsulates apps. It can contain multiple apps, but an app only belongs to one project.

Apps are a lower level units that represent a specific module. For example, in our project, we will create an app called tasks. To do so, change the directory to the django_rest_api_tasks folder like so:

cd django_rest_api_tasks

The run a startapp to create the tasks app:

python startapp tasks

By running the above command, a tasks folder will be created inside the django_rest_api_tasks directory. Go ahead and add tasks to the INSTALLED_APPS list in the django_rest_api_tasks/ file:


We can now start setting up a Django REST API.

Creating a task model

First, we will define the structure of a task model. This defines what data the tasks app will process. Create a task model by navigating to the tasks/ file and add the below code:

from django.db import models

# Create your models here.
class Task(models.Model):
    title = models.CharField(max_length=100)
    description = models.TextField(blank=True, null=True) #description
    completed = models.BooleanField(default=False)
    created_at = models.DateTimeField(auto_now_add=True) #created_at

    def __str__(self):
        #return the task title
        return self.title

This will set up a task with a title, description, completed, and created_at values. Run the migrations command to initialize the above task model to a sqlite database:

python makemigrations tasks

After running the above command, in the tasks folder, under migrations, you will have a file.

To add these model modifications to the sqlite database, we will need to use the command migrate:

python migrate

This will generate a db.sqlite3 file inside the parent django_rest_api_tasks folder. To see whether everything is working properly, start the shell using the following command:

python shell

Inside the shell environment, import the Task model:

from tasks.models import Task

Instantiate the Task model:

t = Task(title="Coding in Python",description="Building a REST API using django")

Save the instantiated record:

Get the saved records:


This will give you the following output:

<QuerySet [<Task: Coding in Python>]>

If you got the above response, the database is working correctly, and you can exit the shell using the following command:


Adding Django REST framework

First and foremost, we must install Django REST framework before we can build up this Django REST API:

python -m pip install djangorestframework

Once the installation is done, on django_rest_api_tasks/, and add rest_framework on the list of installed apps:


In the tasks app directory, create a file. In this file, we will define the model and the fields for the API as follows:

from rest_framework import routers,serializers,viewsets
from .models import Task
class TaskSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Task
        fields = ['id', 'title', 'description', 'completed', 'created_at']

The next step is to set up the various CRUD operation requests that the API will be handling.

Setting up CRUD operations for the Django REST API

An API involves creating, reading, updating, and deleting operations. We need to set up these operations to the to-do list REST API. Navigate to the tasks/ file and follow these steps:

First, add the following imports:

# parsing data from the client
from rest_framework.parsers import JSONParser
# To bypass having a CSRF token
from django.views.decorators.csrf import csrf_exempt
# for sending response to the client
from django.http import HttpResponse, JsonResponse
# API definition for task
from .serializers import TaskSerializer
# Task model
from .models import Task

Next, we will handle incoming requests for getting and creating tasks:

def tasks(request):
    List all task snippets
    if(request.method == 'GET'):
        # get all the tasks
        tasks = Task.objects.all()
        # serialize the task data
        serializer = TaskSerializer(tasks, many=True)
        # return a Json response
        return JsonResponse(,safe=False)
    elif(request.method == 'POST'):
        # parse the incoming information
        data = JSONParser().parse(request)
        # instanciate with the serializer
        serializer = TaskSerializer(data=data)
        # check if the sent information is okay
            # if okay, save it on the database
            # provide a Json Response with the data that was saved
            return JsonResponse(, status=201)
            # provide a Json Response with the necessary error information
        return JsonResponse(serializer.errors, status=400)

Now we can handle incoming requests for updating and deleting a task:

def task_detail(request, pk):
        # obtain the task with the passed id.
        task = Task.objects.get(pk=pk)
        # respond with a 404 error message
        return HttpResponse(status=404)  
    if(request.method == 'PUT'):
        # parse the incoming information
        data = JSONParser().parse(request)  
        # instanciate with the serializer
        serializer = TaskSerializer(task, data=data)
        # check whether the sent information is okay
            # if okay, save it on the database
            # provide a JSON response with the data that was submitted
            return JsonResponse(, status=201)
        # provide a JSON response with the necessary error information
        return JsonResponse(serializer.errors, status=400)
    elif(request.method == 'DELETE'):
        # delete the task
        # return a no content response.
        return HttpResponse(status=204) 

Next, prepare a file in the directory designated for tasks app, and include the following code block in it:

from django.urls import path 
from totasks import views

# define the urls
urlpatterns = [
    path('tasks/', views.tasks),
    path('tasks/<int:pk>/', views.task_detail),

From above, we are defining two URLs:

  1. tasks/ for fetching and adding tasks
  2. /tasks/<int:pk>/ for deleting and updating a task with a dynamic ID

Update django_rest_api_tasks/ as follows to expose these task URLs:

from django.contrib import admin
from django.urls import path,include

urlpatterns = [
    # for tasks
    path('api/', include('tasks.urls')),
    # for admin side

Our API is now fully set! To test it, run the Django development server using the runserver command as shown below:

python runserver

Navigate to your Postman and enter the URL http://localhost:8000/api/ts/. Then execute a GET request to fetch the tasks. Your response should be similar to what you can see here:

Task information in Postman

Setting up a CORS API policy

Because we will be using a client application to communicate to our Django REST API, we need to set up a Cross-Origin Resource Sharing (CORS) API policy.

We have the Django REST API and the Vue client app here. These apps run on different URLs, thus, they have different origins. URLs with similar protocols, domains, and ports are considered to be of the same origin. In this case, the REST API is running on port 8000, so we can’t use this port to run the Vue client app. We will have to access port 8000 and make a request to the REST API to access different task endpoints, and we will have to use a different port to access the Vue app in the browser.

In this case, the application’s URLs will have different origins. Browser security prevents making requests to different origins; the same-origin policy is the term used to describe this limitation. Essentially, it stops a rogue website from accessing sensitive data from a different origin.

In an API context, you can let other origins access some of your API data. Thus, you must use CORS to share your resources.

To set up CORS for our REST API, first stop the development server and install the django-cors-headers package using this command:

python -m pip install django-cors-headers

Then, on the django_rest_api_tasks/django_rest_api_tasks/ file, add corsheaders in the list of installed apps:


In the same file, update MIDDLEWARE as shown below:



For this article, we won’t whitelist any specific origin. We will give full access to the API to any other origins. Therefore, add the following line to the same file:


Finally, use the runserver command to run the development server again:

python runserver

Setting up the Vue.js client app

Go ahead and create a fresh directory and call it client. To set up a basic Vue app, you need to have the Vue CLI installed on your computer.

To install the Vue CLI, run:

npm install -g @vue/cli

In the client folder, open a command prompt and enter the following command to create an instance of the Vue boilerplate for your project:

vue create django_tasks_client

Select default in the resulting menu and wait for CLI to set up the application completely. Once the application has been completed, navigate to the newly created folder:

cd django_tasks_client

Additionally, we will install Axios to handle the communication between the client and Django REST server:

npm install axios

Now you can start the development server to test if everything is working as expected:

npm run serve

You should be able to access the default landing page by loading http://localhost:8080 into your browser.

Fetching tasks

Now we will create Vue components that allow us to perform the CRUD operations to the API.

Create a new Tasks.vue file in your project’s src/components directory. Add the following code within this file.

First, render the view:

    <div class="tasks_container">
        <div class="tasks_content">
            <ul class="tasks_list">
                <li v-for="task in tasks" :key="">
                    <h2>{{ task.title }}</h2>
                    <p>{{ task.description }}</p>
                    <button @click="toggleTask(task)">
                        {{ task.completed ? 'Undo' : 'Complete' }}
                    <button @click="deleteTask(task)">Delete</button>

Next, add a script:

    export default {
        data() {
            return {
                // tasks
                tasks: ['']
        methods: {
            async getData() {
                try {
                    // fetch tasks
                    const response = await this.$http.get('http://localhost:8000/api/tasks/');
                    // set the data returned as tasks
                    this.tasks =; 
                } catch (error) {
                    // log the error
        created() {
            // Fetch tasks on page load

Replace the HelloWorld component with the tasks component in the src/App.vue file, as seen in the following code:

  <div id="app">
    <Tasks />
import Tasks from "./components/Tasks.vue";
export default {
  name: "App",
  components: {
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;

Also, configure Axios in src/main.js by adding the following lines:

// import axios
import axios from 'axios'

// set a prototype for http
Vue.prototype.$http = axios;

Ensure that your development server is still up and running and visit your http://localhost:8080 page.

Creating a task

To handle creating a task, make the following changes on the components/Tasks.vue file:

Add the following view inside tasks_container right above the tasks_content closing div:

<div class="add_task">
    <form v-on:submit.prevent="submitForm">
        <div class="form-group">
            <label for="title">Title</label>
            <input type="text" class="form-control" id="title" v-model="title">
        <div class="form-group">
            <label for="description">Description</label>
            <textarea class="form-control" id="description" v-model="description"></textarea>
        <div class="form-group">
            <button type="submit">Add Task</button>

In the scripts section, navigate to the data() function, and add title and description inside return:

    return {
        tasks: [],
        title: '',
        description: ''

Now, add the submitForm method under methods. This goes below the getData() function like so:

async submitForm(){
    try {
        // Send a POST request to the API
        const response = await this.$'http://localhost:8000/api/tasks/', {
            title: this.title,
            description: this.description,
            completed: false
        // Append the returned data to the tasks array
        // Reset the title and description field values.
        this.title = '';
        this.description = '';
    } catch (error) {
        // Log the error

Ensure that your development server is up and running. Enter a task title and description on the rendered form and click Add Task button. Your task will be submitted and added to the existing tasks.

Updating a task

To update a task, we will implement toggleTask in the methods as shown below:

async toggleTask(task){

        // Send a request to API to update the task
        const response = await this.$http.put(`http://localhost:8000/api/tasks/${}/`, {
            completed: !task.completed,
            title: task.title,
            description: task.description

        // Get the index of the task being updated
        let taskIndex = this.tasks.findIndex(t => ===;

        // Reset the tasks array with the new data of the updated task

        this.tasks = => {
            if(this.tasks.findIndex(t => === === taskIndex){
            return task;


        // Log any error

From your page, click complete for any task. The status of the task will be updated to “done,” and you will have an undo button to show that everything worked correctly.

Deleting a task

Similarly, to handle deleting a task, we will implement the deleteTask function on the async methods as follows:

async deleteTask(task){

    // Confirm if one wants to delete the task
    let confirmation = confirm("Do you want to delete this task?"); 


        // Send a request to delete the task
        await this.$http.delete(`http://localhost:8000/api/tasks/${}`);

        // Refresh the tasks

        // Log any error


From your page, click delete on any task. The task will be deleted and removed from the list.

This guide taught you how you can a full-stack web app using Vue and Django. It creates a minimal learning base that lets you learn and create scalable web applications.

Like other frontend technologies such as React and Angular, Vue provides you with many tools and components to help you hit the ground running. It has an easy learning curve and the capacity to integrate with other technologies such as Django. Check its documentation, and learn more features that its ecosystem has.

Experience your Vue apps exactly how a user does

Debugging Vue.js applications can be difficult, especially when there are dozens, if not hundreds of mutations during a user session. If you’re interested in monitoring and tracking Vue mutations for all of your users in production, try LogRocket. LogRocket Dashboard Free Trial Banner

LogRocket is like a DVR for web and mobile apps, recording literally everything that happens in your Vue apps including network requests, JavaScript errors, performance problems, and much more. Instead of guessing why problems happen, you can aggregate and report on what state your application was in when an issue occurred.

The LogRocket Vuex plugin logs Vuex mutations to the LogRocket console, giving you context around what led to an error, and what state the application was in when an issue occurred.

    1. I agree something is not right with this tutorial I am not able to post data from vue to django only can with django did yo figure it out thanks Im still trying .

      1. The same, I get some errors too, besides that components in Vue.js must be multi- words. And there are other errors in the tutorial, it seems that some revision was missing.

  1. Thank your for this great tutorial. There are just a few minor errors in it:

    * “from totasks import views” → “from tasks import views”
    * “Navigate to your Postman and enter the URL http://localhost:8000/api/ts/” → “…/api/tasks/”
    * It might be worth mentioning that the use of Vue2 is assumed (it does not work out of the box for Vue3)

  2. Thank you for this great tutorial, it helps a lot! and like @Falko said, a few errors in it, and I add some further:
    * correct Vue3 sentence for main.js error in vue project/src:

    const app = createApp(App)
    app.config.globalProperties.$http = axios;

    (instead of using “Vue.prototype.$http = axios;”)

    * toggle and delete’s js error: in task app (python part)

    path(‘tasks/’, views.task_detail),

    toggeTask method in Tasks.vue in component (Vue part)

    const response = await this.$http.put(`http://localhost:8000/api/tasks/${}`, {

    which means unify the expression end with/without slashes of api’s url pattern.

  3. Hi Nice tutorial its my second time attempting this exact tutorial but when I try to submit data from vue js frontend the submit button is not doing anything the only way for me to submit data is to use django. I thought maybe it was due to vue js version or axios version but I did the exact version you used in this tutorial and am still not able to submit data from the frontend to the backend. Do you have a live example to see it working because I followed your example and sadly it does not work. Thank you I would appreciate your help.
