Is it possible to delete browsing history in Express using node.js?

Upon user login, I store user information in browser sessions on the client side (using Angular) like this:

$window.sessionStorage.setItem('loggedInUser', JSON.stringify(val));

For logout authentication on the backend (using Passportjs), I have set up the following route:

app.get('/logout', isLoggedIn, function(req, res) {
    req.logout();
    res.redirect('/');
});

When a user logs out and is redirected, my Angular app does not have access to the '/logout' API endpoint. Therefore, I cannot call

sessionStorage.clear();

because it relies on the '/logout' trigger.

I am wondering if there is a way to clear browser session storage on the backend using Node.js?

Answer №1

If you are looking to prompt the end user's browser to utilize a newer plugin or similar, there are techniques available to achieve this by modifying the file name. In some cases, unique identifiers are added to the end of the file in order to prevent it from being cached or re-cached during download.

While there is an express.js plugin for cachebusting, it may not be essential to install it. However, if you prefer not to reinvent the wheel, you can explore using the following plugin: https://github.com/niftylettuce/express-cachebuster

Various methods exist for handling cached files and ensuring that the client's browser retrieves an updated version. The provided example showcases one approach to achieve this.
