Passport "Hello World" always fails

I have the following:

import {Router} from 'express';
import passport from 'passport';
import {Strategy} from 'passport-local';
import pg from 'pg';
import {pgUri} from '../environment';

let loginRouter = Router();

passport.use(new Strategy((username, password, done) => done(null, true)));
//{
//    pg.connectAsync(pgUri)
//        .then(([client, release]) => {
//            return client.queryAsync('select * from users where "user" = $1::TEXT', [username])
//                .finally(release);
//        })
//        .tap(result => console.log(result.rows))
//        .then(result => done(null, true));
//}));

loginRouter.get('/', (request, response) => response.render('login'));
loginRouter.post('/', passport.authenticate('local', {successRedirect: '/',
                                                      failureRedirect: '/login'}));

export default loginRouter;

      

        
        
        
      

    

This is an express route file that defines the simplest possible authentication scheme. The above will always redirect back to /login

, indicating a failure.

What i tried

• Change failureRedirect
  
  to is /loginFailed
  
  indeed redirected. So the input doesn't work.
• Breakpoints console.log
  
  are not hit inside the function body either.
• Calling done
  
  with done(null, {foo: "bar"})
  
  instead of true does not change anything.

It is worth noting

• I'm using babel for ES6 support, but since this is the only bug and the breakpoints I can set (before passport.use
  
  ) display the expected values ​​for all variables, I don't think that's the problem.
• The route .get()
  
  works as expected, displaying the form.

I have this in my bootstrap:

app.use(session({
    secret: "some-secret",
    resave: true,
    saveUninitialized: true
}));

app.use(passport.initialize());
app.use(passport.session());

passport.serializeUser((user, done) => done(null, {foo: "bar"}));

passport.deserializeUser((user, done) => done(null, {foo: "bar"}));

      

        
        
        
      

    

Here's the form I'm using (directly copied from the example )

<form action="/login" method="post">
    <div>
        <label>Username:</label>
        <input type="text" name="username"/>
    </div>
    <div>
        <label>Password:</label>
        <input type="password" name="password"/>
    </div>
    <div>
        <input type="submit" value="Log In"/>
    </div>
</form>

      

        
        
        
      

    

I have no idea what is wrong here. Would be grateful for any help.
