Creating Sign out

Lecture 309:- Creating Sign out

To create a sign out functionality in our Express.js app, we need to do the following:

1. Install the express-session middleware if you haven't done so already. This middleware is required for using sessions in your Express.js app.

   Copy code

   npm install express-session

2. Require express-session and initialize it in your app using the session middleware.

   javascriptCopy code

   const session = require('express-session'); // Initialize session middleware app.use(session({  secret: 'my-secret-key',  resave: false,  saveUninitialized: false, }));

   Here, we are using the default memory store for sessions. However, it's not recommended for production environments. Instead, you should use a database store like connect-mongo or connect-redis.

3. Create a new route for sign out, and use the req.logout() method to remove the user's session.

   javascriptCopy code

   app.get('/sign-out', (req, res) => {  req.logout();  res.redirect('/'); });

   The req.logout() method is provided by Passport.js, and it removes the user's session from the server. Once the session is removed, the user is no longer considered authenticated.

4. Add a link or button to your views that points to the sign-out route.

   htmlCopy code

   <a href="/sign-out">Sign Out</a>

That's it! Users can now sign out of your app by clicking on the "Sign Out" link or button, and their session will be removed from the server.
