Comprehensive understanding: Vue3 Django4 technology combination to implement full-stack projects

Preface

With the development of the Internet, full-stack development is becoming more and more Popularity. Full-stack development refers to a development model that combines front-end development (Front-end Development) and back-end development (Back-end Development) and is responsible for the development, testing and deployment of applications. In full-stack development, choosing the right combination of technologies is very important. This article will introduce how to use Vue3 and Django4 technology combination to implement a full-stack project, with code examples.

Vue3 Introduction

Vue3 is a popular JavaScript front-end framework, which is the latest version of Vue.js. Compared with Vue2, Vue3 brings many new features and performance optimizations. One of the important improvements is the Composition API. The Composition API allows developers to better organize and reuse component logic, making the code clearer and maintainable. In addition, Vue3 also introduces better performance optimization and some new convenient features, such as Fragments, Teleport and Suspense.

Django4 Introduction

Django is a popular Python backend framework that provides many tools and features for quickly building web applications. Django4 is the latest Django version, which introduces several new features and improvements. One of the important improvements is Django's performance optimization, which allows the application to respond to client requests faster. In addition, Django 4 also provides better database support, API views, and improvements to Django ORM, making it easier for developers to manipulate data.

Vue3 Django4 technology combination to implement a full-stack project

Using the Vue3 and Django4 technology combination, we can implement a complete full-stack project. Below is a simple example that shows how to use Vue3 as the front-end framework, Django4 as the back-end framework, and interact with data through the API.

First, we need to create a Vue3 project. Open the terminal and execute the following command:

vue create frontend

Configure according to the prompts and create a new Vue3 project.

Next, we need to install Django4. Execute the following command in the terminal:

pip install Django

After completing the installation, we can use the following command to create a new Django project:

django-admin startproject backend

After the creation is completed, enter the backend directory and execute the following command Create a new application:

cd backend
python manage.py startapp api

Now we are ready to start writing code.

First, we need to create an API view in Django. Add the following code in the api/views.py file:

from django.http import JsonResponse

def hello(request):
    return JsonResponse({"message": "Hello, World!"})

Next, we need to define the route of the API in the backend/backend/urls.py file:

from django.urls import path
from api.views import hello

urlpatterns = [
    path('api/hello', hello),
]

Then, we need Create a component in Vue3 to call the API. Add the following code in the frontend/src/components/HelloWorld.vue file:

<template>
  <div>
    {{ message }}
  </div>
</template>

<script>
import { ref, onMounted } from 'vue'

export default {
  name: 'HelloWorld',
  setup() {
    const message = ref('')

    onMounted(async () => {
      const response = await fetch('/api/hello')
      const data = await response.json()
      message.value = data.message
    })

    return {
      message
    }
  }
}
</script>

Finally, use the HelloWorld component in the frontend/src/App.vue file:

<template>
  <div id="app">
    <HelloWorld />
  </div>
</template>

<script>
import HelloWorld from './components/HelloWorld.vue'

export default {
  name: 'App',
  components: {
    HelloWorld
  }
}
</script>

We are done Writing of code. Now, we need to start the backend server and frontend server for testing.

Execute the following command in the backend directory to start the Django server:

python manage.py runserver

Execute the following command in the frontend directory to start the Vue server:

npm run serve

Now, open the browser and access http ://localhost:8080, you will see a page that says "Hello, World!" This proves that the technology combination of Vue3 and Django4 successfully implements a full-stack project.

Conclusion

The technology combination of Vue3 and Django4 is a powerful full-stack development tool. By using Vue3 as the front-end framework and Django4 as the back-end framework, we can more easily develop, test and deploy full-stack projects. This article provides a simple example showing how to implement a full-stack project using Vue3 and Django4, with corresponding code examples. I hope this article can help you fully understand the methods and applications of Vue3 Django4 technology combination to implement full-stack projects.
