Building full-stack applications: Vue3 Django4 project development guide

In today's Internet era, full-stack development has become an area of ​​increasing concern. Full-stack developers are not only proficient in front-end technology, but also familiar with back-end development. This article will introduce how to use Vue3 and Django4 to build a full-stack application, and provide some code examples to help readers get started quickly.

First, let us briefly introduce Vue3 and Django4.

Vue3 is the latest version of the Vue.js framework, which has faster rendering speed, smaller size and better development experience. Vue3 introduces the Composition API so that the logic of components can be better organized and reused. At the same time, Vue3 also provides better TypeScript support, making the code more robust and maintainable.

Django4 is an advanced web framework written in Python language. It follows the MTV (model-template-view) design pattern and provides powerful database operation and routing management functions. The features of Django4 include good scalability, high security, and a wealth of development tools and plug-ins.

Below, we will introduce how to use Vue3 and Django4 to build a simple full-stack application. Our full-stack application will implement a user management system, including user registration, login and personal information management functions.

First, we need to create a Django project and set up the database. Suppose our project is named "UserManagement" and the database uses MySQL. You can execute the following commands to create and set up:

$ django-admin startproject UserManagement
$ cd UserManagement
$ python manage.py migrate

Next, we need to create a Django application to handle user-related logic. You can execute the following command to create an application named "user":

$ python manage.py startapp user

After creating the application, we need to register the application in the Django configuration file. Open the UserManagement/settings.py file and add the application name to the INSTALLED_APPS list:

INSTALLED_APPS = [
    ...
    'user',
    ...
]

Then, we need to create a user-related data model. In the user/models.py file, define a model named User, including username, password and other fields:

from django.db import models

class User(models.Model):
    username = models.CharField(max_length=120)
    password = models.CharField(max_length=120)

Next, we need to create User-related views. In the user/views.py file, add the following code:

from django.shortcuts import render
from django.http import JsonResponse

def register(request):
    if request.method == 'POST':
        username = request.POST.get('username')
        password = request.POST.get('password')

        # 在这里进行用户注册逻辑

        return JsonResponse({'message': '注册成功'})
    else:
        return render(request, 'register.html')

def login(request):
    if request.method == 'POST':
        username = request.POST.get('username')
        password = request.POST.get('password')

        # 在这里进行用户登录逻辑

        return JsonResponse({'message': '登录成功'})
    else:
        return render(request, 'login.html')

def profile(request):
    # 在这里进行用户个人信息管理逻辑

    return render(request, 'profile.html')

In the above code, we define three view functions: register for processing User registration logic, login is used to process user login logic, profile is used to process user personal information management logic.

Next, we need to create some Vue components to handle the front-end logic. In Vue3, we can use the createApp function to create an application instance, and the setup function to define the component's logic. In the main.js file, add the following code:

import { createApp } from 'vue'
import App from './App.vue'

const app = createApp(App)
app.mount('#app')

Then, create a file named App.vue in the src directory file, add the following code:

<template>
  <div>
    <router-view></router-view>
  </div>
</template>

<script>
export default {
}
</script>

The above code defines a root component, which contains a component named router-view, which is used to display different pages.

Next, we need to use Vue Router to manage front-end routing. Execute the following command to install Vue Router:

$ npm install vue-router@4

Then, create a file named router.js in the src directory and add the following code:

import { createRouter, createWebHistory } from 'vue-router'
import Register from './views/Register.vue'
import Login from './views/Login.vue'
import Profile from './views/Profile.vue'

const routes = [
  { path: '/register', component: Register },
  { path: '/login', component: Login },
  { path: '/profile', component: Profile },
]

const router = createRouter({
  history: createWebHistory(),
  routes
})

export default router

Next, we need to create some view components to handle the logic of specific pages. In the src/views directory, create Register.vue, Login.vue and Profile.vue files for processing respectively. Logic for user registration, login and personal information management pages.

In the specific view component, we can use Axios to send HTTP requests to the back-end API. Execute the following command to install Axios:

$ npm install axios

In the specific view component, you can use the following code to send a POST request to the back-end API:

import axios from 'axios'

axios.post('/api/register', {
  username: 'Alice',
  password: '123456'
})
.then(response => {
  console.log(response.data.message)
})
.catch(error => {
  console.error(error)
})

The above code sends a user registration request , and prints the returned message to the console.

Finally, we need to mount the Vue application instance and router to the DOM element. In the main.js file, modify it as follows:

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'

const app = createApp(App)
app.use(router)
app.mount('#app')

In the above code, we use app.use(router) to install the Vue Router plug-in, and Use app.mount('#app') to mount the Vue application instance to the DOM element named app.

The above are the general steps for building a full-stack application using Vue3 and Django4. Readers can further improve and optimize this application according to their own needs and preferences. I hope this article can help readers get started with full-stack development quickly.
