Online modeThis is applicable when the user is online and you want to revoke their session via an API call from their frontend client.
signOut
function from the frontend#
Method 1: Call the - ReactJS
- Angular
- Vue
The signOut
method revokes the session on the frontend and backend.
import React from "react";
import { signOut } from "supertokens-auth-react/recipe/passwordless";
function NavBar() {
async function onLogout() {
await signOut();
window.location.href = "/";
}
return (
<ul>
<li>Home</li>
<li onClick={onLogout}>Logout</li>
</ul>
)
}
The signOut
method revokes the session for the user.
import Session from "supertokens-auth-react/recipe/session";
async function logout () {
await Session.signOut();

#
Offline modecaution
This method of revoking a session will only delete the session from the database and not from the frontend.
This implies that the user will still be able to access protected endpoints while their access token is alive.
If you want to instantly logout the user in this mode, you should enable access token blacklisting.
This is applicable when the user is offline, or if you want to revoke their session from the backend.
