Starting from scratch: Vue3+Django4 new technology project

2. Introducing the component
   In the main application, we can introduce our Vue component and render it into the DOM. The following is an example:

3. Back-end development: Django4

1. Creating Django views
   In Django, we can use views to handle HTTP requests and Return response. Here is a simple example:

from django.http import JsonResponse def my_view(request): data = { 'message': 'Hello, Django4', 'description': 'This is a demo project' } return JsonResponse(data)

2. Configuring URL routing
   In Django, we can map requests to the corresponding views through URL routing. The following is an example:

from django.urls import path from .views import my_view urlpatterns = [ path('my-view/', my_view, name='my-view'), ]

4. Connect the front-end and back-end: API interface
After the front-end and back-end are ready, we need to connect them through the API interface. In Vue3, we can use the axios library to send HTTP requests. Here is an example:

import axios from 'axios' axios.get('/api/my-view/') .then(response => { console.log(response.data) }) .catch(error => { console.error(error) })

In Django, we can use Django REST Framework to create and manage API interfaces. The following is an example:

from rest_framework.decorators import api_view from rest_framework.response import Response @api_view(['GET']) def my_view(request): data = { 'message': 'Hello, Django4', 'description': 'This is a demo project' } return Response(data)

5. Project deployment and testing
After completing the development and passing the test, we can deploy the project. For front-end deployment, we can use the Vue CLI's build command to generate static files and deploy them to the server. For backend deployment, we can use Django's runserver command to start the server. We can also use Nginx as a web server to reverse proxy front-end and back-end requests.

6. Summary
By using Vue3 and Django4, we can easily build powerful full-stack technology projects. Vue3's componentization and responsive programming model make front-end development more efficient and elegant. Django4's views, URL routing, and API interfaces make back-end development simpler and more flexible. I hope this article will help you learn and master the technologies of Vue3 and Django4.
