You can use req.login() after successful registration.

From official Passport documentation:

Note: passport.authenticate() middleware invokes req.login() automatically. This function is primarily used when users sign up, during which req.login() can be invoked to automatically log in the newly registered user.

A sample registration code might look like this:

router.post("/register",(req,res) => {
    var user = new User();
    user.name = req.body.name;
    user.email = req.body.email;
    //define other things here
    //create hash and salt here
    user.save().then(user => {
        //on successfult registration
        //login user here, using req.login
        req.login(user ,err => {
            if(!err){
                //redirect to logged-in page
                //or user page
                res.redirect('/')
            }
        })
    })
})

I hope this helps you out.

您可以在成功注册后立即创建令牌并将其发送回注册响应中
