Full stack development in practice: Detailed explanation of Vue3+Django4 project

In the current era of rapid development of the Internet, full-stack development has become a technical direction that has attracted much attention in the field of software development. Through full-stack development, we can handle the development needs of front-end and back-end at the same time, thereby improving development efficiency and user experience. In this article, I will introduce in detail a practical case of full-stack development, that is, the methods and steps of building a project using Vue3 and Django4.

1. Vue3 Introduction
   Vue is a popular front-end framework that is loved by developers for its simplicity, efficiency and flexibility. Vue3 is the latest version of the Vue framework. Compared with Vue2, it has higher performance and a better development experience. Vue3 uses the Composition API to organize, making the code easier to organize and maintain.
2. Django4 Introduction
   Django is a powerful Python web framework that provides a series of tools and functions for quickly developing high-quality web applications. Django 4 is the latest version of the Django framework, which introduces new features such as support for asynchronous views and better database connection management.
3. Project requirements analysis
   Before starting development, we need to clarify the needs and goals of the project. Suppose we want to develop a simple blog application where users can register an account, log in and publish articles. At the same time, we hope to be able to display a list of published articles and support users to comment and like articles. In order to achieve the above functions, we will adopt a front-end and back-end separation architecture. The front-end uses Vue3 and the back-end uses Django4.
4. Front-end development
   First, we need to create a Vue3 project. Execute the following command in the command line:

vue create blog-frontend

Then, we enter the project directory and install the project dependencies:

cd blog-frontend
npm install

Next, we can start writing the front-end code. First, we need to create a login page and registration page, which can be navigated using Vue Router. Then, we can create an article list page to display published articles and provide comments and likes. Finally, we can create an article publishing page for users to publish new articles.

In the front-end development process, we can use Vue's component development method to split the page into multiple components for reuse and maintenance. At the same time, we can use Vue's responsive system to bind and update page data.

5. Back-end development
   In back-end development, we first need to create a Django project. Execute the following command in the command line:

django-admin startproject blog-backend

Then, we enter the project directory and create a Django application:

cd blog-backend
python manage.py startapp blog

Next, we need to create the model class in Django, using Used to define the structure of database tables. In this project, we can create four model classes: User, Article, Comment and Like, which are used to store user information, article information, comment information and like information respectively.

After the model class is created, we can create API views and routes in Django to handle front-end requests. In this project, we need to create APIs such as user registration, user login, article publishing, and article list.

In the back-end development process, we can use the ORM function provided by Django, thus eliminating the step of handwriting SQL. At the same time, we can use Django's template language to render and display front-end pages.

6. Front-end and back-end joint debugging
   After the front-end and back-end code is written, we need to perform front-end and back-end joint debugging to ensure that the two can communicate normally and exchange data with each other.

First, we need to start the backend service. Execute the following command in the project directory:

python manage.py runserver

Then, we need to start the front-end service for development and debugging. Execute the following command in the project directory:

npm run serve

Finally, we can open the front-end page in the browser, click the corresponding button or link, trigger the corresponding HTTP request, and view the results of the request and response.

Through front-end and back-end joint debugging, we can promptly discover and solve problems during the development process to ensure that the project's functions and user experience meet expectations.

7. Project Deployment
   After completing development and testing, we can deploy the project to the production environment. Before deployment, we need to package the front-end code and generate static files.

Execute the following command in the command line:

npm run build

Then, we can place the packaged front-end files into Django’s static file directory and configure servers such as Nginx or Apache , used to forward the user's request to the Django service.

Finally, we need to deploy the Django project to the server and configure the database and other related configurations. You can use tools such as Docker to simplify the deployment process and improve deployment efficiency.

Summary:
Through the above steps, we have introduced in detail the methods and steps for building a full-stack development project using Vue3 and Django4. By separating the front and back ends, we can develop web applications more efficiently and improve development efficiency and user experience. I hope this article can be helpful to everyone's learning and practice in full-stack development.
