Which UI do you use?

Custom UI

Pre built UI

Implementing sign out

The signOut method revokes the session on the frontend and on the backend. Calling this function without a valid session also yields a successful response.

Web

Via NPM

import Session from "supertokens-web-js/recipe/session";

async function logout () {
  await Session.signOut(); 
  window.location.href = "/";
}

Via Script Tag

async function logout () {
  await supertokensSession.signOut(); 
  window.location.href = "/";
}

Mobile

React Native

import SuperTokens from "supertokens-react-native";

async function logout () {
  await SuperTokens.signOut(); 
  // navigate to the login screen..
}

Android

import android.app.Application
import com.supertokens.session.SuperTokens

class MainApplication: Application() {
    fun logout() {
        SuperTokens.signOut(this);
        // navigate to the login screen..
    }
}

iOS

import UIKit
import SuperTokensIOS

class ViewController: UIViewController {
  func signOut() {
    SuperTokens.signOut(completionHandler: {
        error in
        
        if error != nil {
            // handle error
        } else {
            // Signed out successfully
        }
    })
  }
}

Flutter

import 'package:supertokens_flutter/supertokens.dart';

Future<void> signOut() async {
  await SuperTokens.signOut(
    completionHandler: (error) {
      // handle error if any
    }
  );
}

• On success, the signOut function does not redirect the user to another page, so you must redirect the user yourself.
• The signOut function calls the signout API exposed by the session recipe on the backend.
• If you call the signOut function whilst the access token has expired, but the refresh token still exists, our SDKs will do an automatic session refresh before revoking the session.
