Summary of practical experience: Key points of Vue3 Django4 full-stack project development

Introduction:
With the rapid development of the Internet, full-stack development has become a popular development mode. Vue3 and Django4 are currently one of the most popular front-end and back-end frameworks. As a modern JavaScript framework, Vue3 can provide excellent user interface design and responsiveness; Django4 is a fast, safe, and extensible Python framework suitable for building high-quality web applications.

This article will summarize the key points of Vue3 Django4 full-stack project development based on practical experience, and attach some code examples.

1. Project initialization

1. Vue3 project initialization
   First, we need to install the latest version of Vue CLI, install it through the following command:

   npm install -g @vue/cli

   Then, use Vue CLI to create a new Vue project:

   vue create my-project

   During the process of creating the project, you can choose the appropriate configuration, such as selecting the Vue3 version, adding plug-ins, etc.

2. Django4 project initialization
   Install Django4 using the following command:

   pip install Django==4.0.0

   Then, create a new Django project with the following command:

   django-admin startproject my_project

2. Front-end and back-end separation

In Vue3 Django4 full-stack project development, front-end and back-end separation is a common development model. The front-end is responsible for user interface design and user interaction logic, while the back-end is responsible for processing data and logical operations.

1. Front-end development
   Vue3 provides simple and elegant syntax and many practical functions, such as componentization, responsive data binding, routing and state management, etc. The following is a simple Vue3 component example:

   <template>
     <div>
    <h1 id="message">{{ message }}</h1>
    <button @click="updateMessage">Update Message</button>
     </div>
   </template>
   
   <script>
   import { ref } from 'vue';
   
   export default {
     setup() {
    const message = ref('Hello, Vue3!');
    
    const updateMessage = () => {
      message.value = 'Updated Message';
    };
   
    return {
      message,
      updateMessage,
    };
     },
   };
   </script>

2. Back-end development
   Django4 provides powerful models, views, routing and other functions, making it easy to build back-end API interfaces. The following is a simple Django4 view function example:

   from django.http import JsonResponse
   
   def hello(request):
    return JsonResponse({'message': 'Hello, Django4!'})

   Here we use JsonResponse to return a JSON formatted response.

3. Data interaction

In the development of Vue3 Django4 full-stack project, the interaction of front-end and back-end data is very important. Usually we use HTTP protocol for data transmission.

1. Front-end data request
   In Vue3, we can use the axios library to send HTTP requests. Here is an example of sending a GET request using axios:

   import axios from 'axios';
   
   axios.get('/api/data')
     .then(response => {
    console.log(response.data);
     })
     .catch(error => {
    console.error(error);
     });

2. Backend Data Processing
   In Django4, we can use django.views Module to handle HTTP requests. Here is an example of a Django4 view function that handles GET requests:

   from django.http import JsonResponse
   
   def get_data(request):
    data = {
        'name': 'John',
        'age': 25,
    }
    return JsonResponse(data)

   Here we return a JSON response containing name and age.

4. Project Deployment

When the development is completed, we need to deploy the Vue3 front-end and Django4 back-end to the server for access.

1. Front-end deployment
   In Vue3, we can use the npm run build command to build the front-end code for the production environment. After the build is completed, the generated static files will be stored in the dist directory. Just deploy the files in the dist directory to the Web server.

2. Backend deployment
   For Django4, we can use WSGI servers such as gunicorn to deploy Django applications on the server. The following is an example command to deploy Django4 using gunicorn:

   gunicorn my_project.wsgi:application

   can be configured according to actual needs, such as binding IP address and port, etc.

Summary:
This article summarizes the key points of Vue3 Django4 full-stack project development, including project initialization, front-end and back-end separation, data interaction and project deployment. Through these key points and code examples, I believe readers can quickly get started developing Vue3 Django4 full-stack projects and achieve good development results.
