@types/express-session

What is @types/express-session?

@types/express-session provides TypeScript type definitions for the express-session middleware, which is used to manage user sessions in Express applications.

What are @types/express-session's main functionalities?

Session Management

This code demonstrates how to set up basic session management in an Express application using express-session. It initializes the session middleware with a secret key and configures session options like resave and saveUninitialized.

const session = require('express-session');
const express = require('express');
const app = express();

app.use(session({
  secret: 'your-secret-key',
  resave: false,
  saveUninitialized: true,
  cookie: { secure: true }
}));

app.get('/', (req, res) => {
  if (req.session.views) {
    req.session.views++;
    res.send(`Number of views: ${req.session.views}`);
  } else {
    req.session.views = 1;
    res.send('Welcome to the session demo. Refresh!');
  }
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

Custom Session Store

This code demonstrates how to use a custom session store with express-session. In this example, sessions are stored in a MongoDB database using the connect-mongo package.

const session = require('express-session');
const MongoStore = require('connect-mongo');
const express = require('express');
const app = express();

app.use(session({
  secret: 'your-secret-key',
  resave: false,
  saveUninitialized: true,
  store: MongoStore.create({ mongoUrl: 'mongodb://localhost/test-app' })
}));

app.get('/', (req, res) => {
  if (req.session.views) {
    req.session.views++;
    res.send(`Number of views: ${req.session.views}`);
  } else {
    req.session.views = 1;
    res.send('Welcome to the session demo. Refresh!');
  }
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

Session Data

This code demonstrates how to store and retrieve session data. In this example, user information is stored in the session upon login and retrieved when accessing the profile route.

const session = require('express-session');
const express = require('express');
const app = express();

app.use(session({
  secret: 'your-secret-key',
  resave: false,
  saveUninitialized: true,
  cookie: { secure: true }
}));

app.get('/login', (req, res) => {
  req.session.user = { username: 'john_doe' };
  res.send('User logged in');
});

app.get('/profile', (req, res) => {
  if (req.session.user) {
    res.send(`User profile: ${req.session.user.username}`);
  } else {
    res.send('No user logged in');
  }
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

Other packages similar to @types/express-session

express-session

express-session is the core package for managing sessions in Express applications. It provides the middleware necessary to handle session creation, storage, and management. @types/express-session provides TypeScript definitions for this package.

cookie-session

cookie-session is an alternative to express-session that stores session data in cookies instead of on the server. This can simplify session management but is limited by the size constraints of cookies.

client-sessions

client-sessions is another package for managing sessions in Express applications. It stores session data on the client side in a tamper-proof cookie, providing a stateless session management solution.
