Login with Facebook on NodeJS

There is an easy way on NodeJS to handle logins with Facebook, Google, LinkedIn, Twitter and so on, you can use passport.

npm i passport --save
npm i passport-facebook --save

To use it:

import passport = require("passport");
var FacebookStrategy = require("passport-facebook").Strategy;

Then you have to configure the provider:

passport.use(new FacebookStrategy({
    clientID: oauthSettings.FacebookID,
    clientSecret: oauthSettings.FacebookSecret,
    callbackURL: "http://localhost:1337/auth/facebook/callback"
    function (accessToken, refreshToken, profile, done)
        // you email, name, id, and so on is on profile
        var result = profile; 

You can get a clientID and clientSecret by going to developers.facebook.com. Add a platform on your application and on the website enter “localhost:1337”.

You also have to configure two routes, one to trigger the login and the other one what you specified on the callbackURL above to handle the return result from Facebook.

app.get("/auth/facebook", passport.authenticate("facebook"));

    passport.authenticate("facebook", {
        successRedirect: "/",
        failureRedirect: "/login"

Start your application on localhost:1337 and you are good to go, it should work.
