Master core technologies: Vue3+Django4 full stack development

Master core technology: Vue3 Django4 full-stack development

In modern software development, full-stack development has received more and more attention. Full-stack development engineers can handle tasks such as front-end and back-end development, as well as database operations simultaneously. In this article, we will explore how to use Vue3 and Django4, two popular development frameworks, for full-stack development and provide some code examples.

  1. Preface

Vue3 is the latest Vue.js version, which provides developers with better performance and maintainability. Django4 is a popular back-end framework in the Python language, which provides powerful database operations and web development functions. By combining Vue3 and Django4, we can implement an efficient, flexible and scalable full-stack application.

  1. Front-end development: Vue3

First, we need to set up a Vue3 project. Create a new Vue3 project using the following command:

vue create vue3-django4-full-stack

Next, we can create a Vue component and start front-end development. In Vue3, the way components are written has changed slightly. Here is a simple example:

<template>
  <div>
    <h1>{{ message }}</h1>
  </div>
</template>

<script>
export default {
  data() {
    return {
      message: 'Hello, Vue3!'
    }
  }
}
</script>

In this example, we define a Vue component and use the data option to define a message variable. Then, reference this variable in the template to display a message.

  1. Back-end development: Django4

Now, we need to set up a Django4 project. Create a new Django4 project using the following command:

django-admin startproject django4_full_stack

Then, we need to create a Django application and start backend development. Create a new Django application using the following command:

cd django4_full_stack
python manage.py startapp backend

Next, create a views.py file under the backend directory and add the following code example:

from django.http import JsonResponse

def hello_vue(request):
    message = "Hello, Django4!"
    return JsonResponse({'message': message})

In this example, we define a view function hello_vue that handles API requests and returns a JSON response containing a message.

  1. Front-end and back-end interaction: API call

Now, we need to call the back-end API in the front-end component. In Vue3, we can use the axios library to send HTTP requests. In the Vue component, we can use the following code to call the backend API:

import axios from 'axios';

export default {
  data() {
    return {
      message: ''
    }
  },
  mounted() {
    axios.get('http://localhost:8000/api/hello_vue')
      .then(response => {
        this.message = response.data.message;
      })
      .catch(error => {
        console.log(error);
      });
  }
}

In this example, we use the axios.get method to send a GET request to http: //localhost:8000/api/hello_vue address, and assign the returned message to the message variable when responding successfully.

  1. Start the application

Now, we have completed the development of the front-end and back-end, and established a simple API interaction between the front-end and the back-end. Next, we need to start the front-end and back-end development servers. In one terminal window, run the Vue3 development server with the following command:

cd vue3-django4-full-stack
npm run serve

In another terminal window, run the Django4 development server with the following command:

cd django4_full_stack
python manage.py runserver

Now, we can Visit http://localhost:8080 and see the message displayed in the front-end component.

Summary

This article introduces how to use Vue3 and Django4 for full-stack development and provides some code examples. By learning Vue3 and Django4, two popular development frameworks, we can build efficient, flexible and scalable full-stack applications. I hope this article can help you master these two key technologies and play a role in full-stack development.
