googleapis oauth2.0 + 用户注册通行证 - nodejs express 应用

Question

I am using googleapis oauth2.0 for user registration on my website through through OAuth2.0 . I get to the point where I get the access token and id token and save the new user in my database, from that point on I want to create a user session and I am trying to use passport for it but passport needs one of its strategies to implement which I do not need at this point because I already have verified user email and everything and have saved the user in my database all I now need to do is create a user session and send the user to the home page but there seems to be no way to just create user session without a strategy in passport .

here is my oauth2.0 redirect function where I get the access token etc.

router.get('/oauth-redirect', function (req, res, next) = > {
    const data = await googleAuth.getToken(req.code);
    const user = getUserInfoFrom(data);
    const savedUser = save(user);
    //here: use passport to create a session and send the user to home page ????
    
})

found the way to do it, there is req.login() function exposed by passport that you can use to manually log the user in.

router.get('/oauth-redirect', function (req, res, next) = > {
    const data = await googleAuth.getToken(req.code);
    const user = getUserInfoFrom(data);
    const savedUser = save(user);
    //this below is what will create a session and will set connect.sid cookie
    req.login(savedUser, function(err) {
        if (err) {
            console.log(err);
        }
        return res.redirect('/home');
    });
    
})
