Revoking a session

Online mode

This is applicable when the user is online and you want to revoke their session via an API call from their frontend client.

Method 1: Call the signOut function from the frontend

ReactJS

The signOut method revokes the session on the frontend and backend.

import React from "react";import { signOut } from "supertokens-auth-react/recipe/thirdpartypasswordless";
function NavBar() {  async function onLogout() {    await signOut();    window.location.href = "/";  }  return (    <ul>      <li>Home</li>      <li onClick={onLogout}>Logout</li>
    </ul>  )}

Angular

The signOut method revokes the session for the user.

import Session from "supertokens-web-js/recipe/session";
async function logout () {  await Session.signOut();   window.location.href = "/";}

Vue

The signOut method revokes the session for the user.

import Session from "supertokens-web-js/recipe/session";
async function logout () {  await Session.signOut();   window.location.href = "/";}

Method 2: Call the revokeSession function post session verification on the backend

NodeJS

Express

import express from "express";import { verifySession } from "supertokens-node/recipe/session/framework/express";import { SessionRequest } from "supertokens-node/framework/express";
let app = express();
app.post("/someapi", verifySession(), async (req: SessionRequest, res) => {
    // This will delete the session from the db and from the frontend (cookies)    await req.session!.revokeSession();
    res.send("Success! User session revoked");});

Hapi

import Hapi from "@hapi/hapi";import { verifySession } from "supertokens-node/recipe/session/framework/hapi";import { SessionRequest } from "supertokens-node/framework/hapi";
let server = Hapi.server({ port: 8000 });
server.route({    path: "/someapi",    method: "post",    options: {        pre: [            {                method: verifySession()            },        ],    },    handler: async (req: SessionRequest, res) => {        // This will delete the session from the db and from the frontend (cookies)        await req.session!.revokeSession();        return res.response("Success! User session revoked").code(200);    }})

Fastify

import Fastify from "fastify";import { verifySession } from "supertokens-node/recipe/session/framework/fastify";import { SessionRequest } from "supertokens-node/framework/fastify";
let fastify = Fastify();
fastify.post("/someapi", {    preHandler: verifySession(),}, async (req: SessionRequest, res) => {    // This will delete the session from the db and from the frontend (cookies)    await req.session!.revokeSession();
    res.send("Success! User session revoked");});

Koa

import { verifySession } from "supertokens-node/recipe/session/framework/awsLambda";import { SessionEvent } from "supertokens-node/framework/awsLambda";
async function someapi(awsEvent: SessionEvent) {    // This will delete the session from the db and from the frontend (cookies)    await awsEvent.session!.revokeSession();
    return {        body: JSON.stringify({ message: "Success! User session revoked" }),        statusCode: 200,    };};
exports.handler = verifySession(someapi);

Loopback

import KoaRouter from "koa-router";import { verifySession } from "supertokens-node/recipe/session/framework/koa";import { SessionContext } from 'supertokens-node/framework/koa';
let router = new KoaRouter();
router.post("/someapi", verifySession(), async (ctx: SessionContext, next) => {    // This will delete the session from the db and from the frontend (cookies)    await ctx.session!.revokeSession();
    ctx.body = "Success! User session revoked";});

AWS Lambda / Netlify

import { inject, intercept } from "@loopback/core";import { RestBindings, post, response } from "@loopback/rest";import { verifySession } from "supertokens-node/recipe/session/framework/loopback";import { SessionContext } from "supertokens-node/framework/loopback";
class Logout {    constructor(@inject(RestBindings.Http.CONTEXT) private ctx: SessionContext) { }    @post("/someapi")    @intercept(verifySession())    @response(200)    async handler() {        // This will delete the session from the db and from the frontend (cookies)        await this.ctx.session!.revokeSession();
        return "Success! User session revoked";    }}

Next.js

import { superTokensNextWrapper } from 'supertokens-node/nextjs'import { verifySession } from "supertokens-node/recipe/session/framework/express";import { SessionRequest } from "supertokens-node/framework/express";
export default async function someapi(req: SessionRequest, res: any) {    await superTokensNextWrapper(        async (next) => {            await verifySession()(req, res, next);        },        req,        res    )    // This will delete the session from the db and from the frontend (cookies)    await req.session!.revokeSession();    res.send("Success! User session revoked");}

NestJS

import { Controller, Post, UseGuards, Request, Response, Session } from "@nestjs/common";import { SessionContainer } from "supertokens-node/recipe/session";import { AuthGuard } from './auth/auth.guard';
@Controller()export class ExampleController {  // For more information about "AuthGuard" and the "Session" decorator please read our NestJS guide.  @Post('someapi')  @UseGuards(new AuthGuard())  async postSomeAPI(@Session() session: SessionContainer): Promise<string> {    await session.revokeSession();
    return "Success! User session revoked";  }}

GoLang

import (    "net/http"
    "github.com/supertokens/supertokens-golang/recipe/session"    "github.com/supertokens/supertokens-golang/supertokens")
func someAPI(w http.ResponseWriter, r *http.Request) {    // retrieve the session object as shown below    sessionContainer := session.GetSessionFromRequestContext(r.Context())
    // This will delete the session from the db and from the frontend (cookies)    err := sessionContainer.RevokeSession()    if err != nil {        err = supertokens.ErrorHandler(err, r, w)        if err != nil {            // TODO: Send 500 status code to client        }        return    }
    // TODO: Send 200 response to client}

Python

FastAPI

async def some_api(session: SessionContainer = Depends(verify_session())):    await session.revoke_session() # This will delete the session from the db and from the frontend (cookies)    return PlainTextResponse(content='success')

Flask

from supertokens_python.recipe.session.framework.flask import verify_sessionfrom supertokens_python.recipe.session import SessionContainerfrom flask import g

    session.sync_revoke_session() # This will delete the session from the db and from the frontend (cookies)    return 'success'

Django

from supertokens_python.recipe.session.framework.django.asyncio import verify_sessionfrom django.http import HttpRequestfrom supertokens_python.recipe.session import SessionContainer
@verify_session()async def some_api(request: HttpRequest):    session: SessionContainer = request.supertokens  This will delete the session from the db and from the frontend (cookies)    await session.revoke_session()

Offline mode

caution

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.

Method 1: Revoke a session using its sessionHandle

NodeJS

import Session from "supertokens-node/recipe/session";
async function revokeSession(sessionHandle: string) {    let revoked = await Session.revokeSession(sessionHandle);};

GoLang

import "github.com/supertokens/supertokens-golang/recipe/session"
func main() {    sessionHandle := "someSessionHandle"    revoked, err := session.RevokeSession(sessionHandle)    if err != nil {        // TODO: Handle error        return    }
    if revoked {        // session was revoked    } else {        // session was not found    }}

Python

Asyncio

from supertokens_python.recipe.session.asyncio import revoke_session
async def some_func():    session_handle = "someSessionHandle"    _ = await revoke_session(session_handle)

Syncio

from supertokens_python.recipe.session.syncio import revoke_session
session_handle = "someSessionHandle"revoked = revoke_session(session_handle)

You can fetch all of the sessionHandles for a user using the getAllSessionHandlesForUser function

Method 2: Revoke all sessions for a user

NodeJS

import express from "express";import Session from "supertokens-node/recipe/session";
let app = express();
app.use("/revoke-all-user-sessions", async (req, res) => {
    let userId = req.body.userId    await Session.revokeAllSessionsForUser(userId);
    res.send("Success! All user sessions have been revoked");});

GoLang

import (    "fmt"
    "github.com/supertokens/supertokens-golang/recipe/session")
func main() {    revokedSessionHandles, err := session.RevokeAllSessionsForUser("userId")    if err != nil {        // TODO: Handle error        return    }
    // revokedSessionHandles is an array of revoked session handles.    fmt.Println(revokedSessionHandles)}

Python

Asyncio

from supertokens_python.recipe.session.asyncio import revoke_all_sessions_for_user
async def some_func():    user_id = "someUserId"    revoked_session_handles = await revoke_all_sessions_for_user(user_id)
    print(revoked_session_handles) # revoked_session_handles is an array of revoked session handles.

Syncio

from supertokens_python.recipe.session.syncio import revoke_all_sessions_for_user
user_id = "someUserId"revoked_session_handles = revoke_all_sessions_for_user(user_id)
# revoked_session_handles is an array of revoked session handles.
