Refresh Auth0 configuration

Implement Auth0 configuration

Currently we used passwordless authentication sessions, now we are creating a universal login flow You will be changing the authentication route and parallel messages/tests

Tasks

To implement the Universal Login flow for Auth0, you will need to make some changes to your authentication.js file. Here are the steps you can follow:

• [ ] 1. Install the express-session and passport packages: npm install express-session passport
• [ ] 2. Install the passport-auth0 package: npm install passport-auth0
• [ ] 3. Require the passport and express-session packages at the top of your file:

const passport = require('passport')
const session = require('express-session')

• [ ] 4. Add the following middleware to your Express app to enable sessions:

app.use(session({
  secret: 'your-secret-key',
  resave: false,
  saveUninitialized: true
}))

• [ ] 5. Initialize Passport and add the middleware to your Express app:)

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

• [ ] 6. Configure Passport to use the passport-auth0 strategy:

const Auth0Strategy = require('passport-auth0')

const strategy = new Auth0Strategy({
  domain: 'your-auth0-domain',
  clientID: 'your-client-id',
  clientSecret: 'your-client-secret',
  callbackURL: 'http://localhost:3000/callback'
}, (accessToken, refreshToken, extraParams, profile, done) => {
  return done(null, profile)
})

passport.use(strategy)

passport.serializeUser((user, done) => {
  done(null, user)
})

passport.deserializeUser((user, done) => {
  done(null, user)
})

• [ ] 7. Replace your-auth0-domain, your-client-id, and your-client-secret with your own values. Modify the /isAuthenticated route to use Passport's authenticate method:

router.get('/isAuthenticated', passport.authenticate('auth0'), (req, res) => {
  res.send(true)
})

• [ ] 8. Modify the /protected-message route to use Passport's authenticate method:

router.get('/protected-message', passport.authenticate('auth0'), (req, res) => {
  const message = getProtectedMessage()
  res.status(200).send(message)
})

• [ ] 9. Add a new route for the Auth0 login page:

router.get('/login', passport.authenticate('auth0', {
  scope: 'openid email profile'
}), (req, res) => {
  res.redirect('/')
})

• [ ] 10. Add a new route for the Auth0 callback:

router.get('/callback', passport.authenticate('auth0', {
  failureRedirect: '/login'
}), (req, res) => {
  res.redirect('/')
})

• [ ] 11. Modify the /public-message route to redirect to the Auth0 login page if the user is not authenticated:

router.get('/public-message', (req, res) => {
  if (req.isAuthenticated()) {
    const message = getPublicMessage()
    res.status(200).send(message)
  } else {
    res.redirect('/login')
  }
})

That's it! With these changes, your app should now use the Universal Login flow for Auth0.
