Integrating json web token in oauth20 - node.js

Question

I am trying to create an api where user can sign up with an email or can sign in with google, I use json web token for authentication and oauth20, the problem is, can, I pass a jwt with oauth?
I have tried passing it and, I get a token if, I console log, but how do, I pass it to the user, like can i some way attach it to the req.user object in the cb by oauth or something like that?
I am doing this in the google strategy:
async (accessToken, refreshToken, params, profile, cb) => {
const userCheck = await User.findOne({ googleId: profile.id });
if (userCheck) {
const payload = {
user: {
id: userCheck.id
}
};
jwtToken.sign(
payload,
config.get("jwtSecret"),
{ expiresIn: 360000 },
(err, token) => {
if (err) {
throw err;
}
// console.log(token);
return res.json({ token });
},
cb(null, userCheck)
);
My routes are protected like this:
router.get("/", auth, async (req, res)=>{
...some code
}
where auth is a middle ware function
This is the Auth middleware function:
module.exports = function(req, res, next) {
const token = req.header("x-auth-token");
// If no token found
if (!token)
{
return res.status(401).json({ msg: "User not authorized" });
}
// Set token to user
try {
const decoded = jwtToken.verify(token, config.get("jwtSecret"));
req.user = decoded.user;
}
catch (err)
{
res.
status(401)
.json({ msg: "User not authenticated, please login or sign up" });
}
next();
};

I found the solution, you need to pass sign the token in the passport.serializeUser and then send the it with a redirection in response of the redirect url.
The serialize user function:
passport.serializeUser(async (user, cb) => {
const payload = {
user: {
id: user.id
}
};
token = jwtToken.sign(payload, config.get("jwtSecret"), {
expiresIn: 360000
});
console.log("serialize");
cb(null, user.id);
});
The redirection route:
router.get(
"/google/redirect",
passport.authenticate("google", { sessionStorage: false }),
(req, res) => {
res.redirect("/" + token);
}
);
