I have made a login system with jwt and, basically, the user redirects to the homepage (homepage/) if login (homepage/login) is successfull. After that, even if the user types (homepage/login) in the url, they get redirected back to the homepage because (and as long as) they have the jwt token.
I have the following code:
app.get('/login', (req, res) => {
const token = req.cookies.jwt
if(token) {
res.redirect('/')
} else {
res.render('login')
}
})
HOWEVER, if the user goes to (homepage/login) through the "back button", they are no longer redirected even though they have the token. How can I include a redirect if the back button is pressed ?
Redirection is happening on client side.
So, simply include a frontend javascript code that checks if token is there. If not present, redirect.
In html code, include this script in head tag (assuming you are using localstorage to store token:
<html>
<head>
..
..
<script>
const token = localstorage.getItem("token");
if(token == null) {
window.location.replace("-path-to-home-page-");
}
</script>
</head>
<body>
..
..
..
</body>
</html>
