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.
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.
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.
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.
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.
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.
