How to pass jwtPayload data decoded by Passport to nodejs API - node.js

Question

I am using this passport strategy.
passport.use(
'onlyForRefreshToken',
new JWTStrategy(
{
jwtFromRequest: ExtractJWT.fromAuthHeaderAsBearerToken(),
secretOrKey: jwtSecretRider,
},
(jwtPayload, done) => {
if (jwtPayload) {
return done(null, jwtPayload);
}
return done(null, false);
},
),
);
My goal is Putting 'jwtPayload' into my rest API of Nodejs that is located at other folder.
That is, I want to use jwtPayload decoded at the code below.
exports.riderRefreshToken = async (req, res) => {
const { email } = req.body;
const exRiderRefreshToken = await Rider.findOne({ email });
}
And this router works by middleware of jwtstrategy.
router.post(
'/refreshToken',
passport.authenticate('onlyForRefreshToken', { session: false }),
authenticationCtrl.riderRefreshToken,
);
In conclusion, when JWT passes from jwtstrategy without problem, that Post router would work.
And I want to use jwtPayload that is in jwtstrategy into Nodejs API as req.params or req.body.
Could you help me this problem?

You need to wrap your strategy into a function that gets req and res :
const isAuthenticated: RequestHandler = (req, res, next) => {
passport.authenticate(
'jwt',
{ session: false, failWithError: true },
(error, user) => {
if (error) {
return next(error)
}
//HERE PUT USER WHERE YOU WANT
//req.data or req.user or req.userInfo
req.user = user
return next()
}
)(req, res, next)
}
I don't recommend putting the user into req.params nor req.body since it might be confusing later on (because technically it doesn't come from those).
