Hello,
You can use the wixusers.logout function to log users out. If you wanted to just check when the user has logged out you can run a condition that checks if a user is not logged in.
I created a simple example for demonstration:
import wixUsers from 'wix-users';
$w.onReady(function () {
let user = wixUsers.currentUser;
let isLoggedIn = user.loggedIn;
if(!isLoggedIn){
console.log("Not logged in");
}
})
See currentuser API
I hope this helps!
Best regards,
Miguel
