I'm implementing facebook-auth using https://www.npmjs.com/package/passport and https://www.npmjs.com/package/passport-facebook-token npm packages
this is my code in the passport config file:
passport.use(
new FacebookTokenStrategy(
{
clientID: config.FACEBOOK_CLIENT_ID,
clientSecret: config.FACEBOOK_CLIENT_SECRET,
fbGraphVersion: 'v3.0',
},
(accessToken, refreshToken, profile, done) => {
User.findOne(
{ 'facebookProvider.id': profile.id },
(error: any, user: any) => {
if (!user) {
const newUser = new User({
name: profile.displayName,
email: profile.emails[0].value,
facebookProvider: { id: profile.id, token: accessToken },
imageProfile: profile.photos[0].value,
});
newUser.save((error, result) => {
if (error) {
return done(error);
}
return done(null, result);
});
}
return done(error, user);
}
);
}
)
);
and below is my route handler:
const authRouter = express.Router();
authRouter
.route('/facebook')
.get(
passport.authenticate('facebook-token'),
async (req: Request, res: Response) => {
if (req.user) {
const accessToken: String = jwt.sign(
{ user: req.user },
config.JWT_SECRET_KEY,
{
expiresIn: config.TOKEN_LIFE_TIME,
}
);
return sendSuccesResponse(res, 200, accessToken);
}
return sendErrorResponse(res, 400, 'Something went wrong');
}
);
export default authRouter;
also, I initialized the passport in the index.ts file which is the entry point of API and imported the passport config file:
import './config/passport';
.
.
.
app.use(passport.initialize());
app.use('/api/v1/oauth2', authRouter);
Moreover, I got the token from Facebook and when I request my API with the provided token, Facebook can authenticate and return the user profile but after authentication and creating a new user or if the user already exists in DB, then it does not go to the route handler where I want to generate JWT token for the user and return to the user.
I got the following error in postman: 500 internal server error
