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');
});
