Can Redis be used for session management in a Node.js application?

Yes, Redis is an excellent choice for session management. Store session data (user ID, login status, etc.) in Redis, using the session ID as the key. Use a middleware like `connect-redis` to integrate Redis with Express.js sessions: ```javascript const session = require('express-session'); const RedisStore = require('connect-redis').default; app.use(session({ store: new RedisStore({ client: client }), secret: 'your-secret-key', resave: false, saveUninitialized: false })); ``` This stores session data in Redis, providing scalability and persistence.
