Start from scratch: Vue3 Django4 new technology project

Introduction:
In today's rapidly developing technology field, full-stack development has become a trend. As popular frameworks for front-end and back-end development, Vue and Django not only have a wide range of application backgrounds, but also bring more interesting and powerful features in the latest versions. This article will introduce how to use Vue3 and Django4 to build a new technology project, and demonstrate their power through code examples.

1. Project planning and preparation
Before starting, we need to plan and prepare the project. First, we need to make sure we have Node.js, Python, and the Django development environment installed. We can then create a new Vue project by installing the Vue CLI with the following command:

npm install -g @vue/cli
vue create my-project
cd my-project

Next, we are ready to create the Django project. Install Django through the following command:

pip install Django

Then, we can create a new Django project through the following command:

django-admin startproject myproject
cd myproject

2. Front-end development: Vue3

1. Create Vue components
   In Vue3, we can use<script setup> syntax to write components. Here is a simple example:

<template>
  <div>
    <h1 id="message">{{ message }}</h1>
    <p>{{ description }}</p>
  </div>
</template>

<script setup>
import { ref } from 'vue'

const message = ref('Hello, Vue3')
const description = ref('This is a demo project')
</script>

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:

<template>
  <div>
    <my-component></my-component>
  </div>
</template>

<script setup>
import MyComponent from '@/components/MyComponent.vue'
</script>

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.
