I have implemented authentication in my express app using passport, passport-local and passport-jwt. The login code below generates a token which is then sent back via the response object. However, when attempting to login using Postman, the request never completes.
passport.use('login', localStrategyLogin);
passport.serializeUser(function (user, done) {
done(null, user._id)
});
app.use(passport.initialize());
app.post('/login', (req, res, next) => {
passport.authenticate('login', {session: false}, (err, user, info) => {
if (err) {
return next(err);
}
if (!user) {
return next(new Error("Could not find user"));
}
req.login(user, {session: false}, (error) => {
if (error) return next(error);
const token = jwt.sign({_id: user._id, email: user.email}, JWT_SECRET, {expiresIn: JWT_EXPIRES});
res.send({token});
});
})(req, res, next);
});
Login Strategy:
import { Strategy as LocalStrategy } from 'passport-local';
import User from "../models/User";
export const localStrategyLogin = new LocalStrategy({usernameField: 'email', passwordField: 'password'}, async function (email, password, done) {
try {
const user = await User.findByLogin({email, password});
if (user) return done(null, user);
} catch (e) {
console.log(e.message);
}
return done(null, false, {message: 'Incorrect email or password.'});
});
