Design and implementation principles of user session management mechanism in e-commerce website development

User session management is a very important aspect of e-commerce website development. It is responsible for tracking the user's login status, storing user information, and ensuring a consistent user experience throughout the website session. In this article, we will discuss the design and implementation principles of the user session management mechanism, and use JavaScript to demonstrate the corresponding source code.

1. The basic principle of session management The
   basic principle of session management is to store user-related information on the server side and assign a unique session identifier to each session. When a user visits a website, the server generates a session identifier and stores it in a cookie on the user's browser. The user's request will carry this session identifier, and the server identifies the user by checking the identifier and associates relevant information with the session.

2. Creating a session identifier
   In JavaScript, we can use uuidthe library to generate a unique session identifier. First, we need to install uuidthe library, which can be installed using npm:

npm install uuid

Then, import the library in your code uuidand use it to generate session identifiers:

const {
   
    
     v4: uuidv4 } =
