How would I redirect the client to another page upon auth?

Question

This is the code I run once a user clicks the Sign In button:

 app.post('/api/sign-in', function(req, res, next) {
firebase.auth().signInWithEmailAndPassword(req.body.email, req.body.password).then(function (user) {
console.log('a new user has signed in! their e-mail address: '+user.email+' | User ID: '+user.uid)
}).catch(function(error) {
console.log(error)
})
})

What would be the appropriate way of 'transferring' the user to another page (for example, members area)? Would I stick that code in the callback method?

Your node server should probably return the auth token to the client, then the client handles the direct, probably using window.location. Though you could also return a 302 status.
