ExpressJS HTTPS Firebase Auth Restful Webservices Framework

So, if you've read through my blog you'd, know by now, that I do make Restful web services for Java / PHP and I've recently started working with Node.JS and Firebase. Hence, I've decided to create my own HTTPS Restful web services framework that is built on express for Firebase. As follows.


var express = require('express');// Enable Express
var app = express();

var fs = require('fs');//Enable Https
var https = require('https');


var cors = require('cors'); // Add CORS for browser requests


var firebase = require('firebase');// Enable Firebase
  firebase.initializeApp({
  serviceAccount: 'Something.json here', // Add Firebase key JSON
  databaseURL: 'Firebase db endpoint here' // Add Firebase endpoint
});


// Add endpoint for CORS
app.use(cors({origin: 'Script origin here'}));


// Create Https Server
https.createServer({
      key: fs.readFileSync('key.pem'),
      cert: fs.readFileSync('cert.pem')
    }, app).listen(8081);



app.post("/YOUR_ENDPOINT_NAME", function (req, res) {

firebase.auth().verifyIdToken(req.body.Token).then(function(decodedToken) {

  var uid = decodedToken.uid;
  if(uid ===req.body.uid){
   /*
    *
    *
    *
* Do your work here.
*
*
*
*
*/

  }else{

// If token UID doesnt Match
var info={
message:"Bad Token",
success:false
}
        res.json(info);
  }
}).catch(function(error) { // If theres a Token Error
var info={
message:(error.code + ' - '+ error.message),
success:false
}
res.json(info);
});
});



This is a simple Node.JS Restful framework that is built on expressJS and uses HTTPS.
It has been built to simplify Firebase web services deployment and demonstrate secure Restful web service creation with Firebase.
Ideally, it is geared towards Firebase developers who need to create backend web services, as a mechanism for fast deployment.

Dependencies:

Node.JS
ExpressJS
CORS
https
fs
Firebase


Resources:

Firebase - https://www.firebase.com/docs/
Express - https://expressjs.com/
Cors - https://www.npmjs.com/package/cors
HTTPS - http://blog.mgechev.com/2014/02/19/create-https-tls-ssl-application-with-express-nodejs/
FS - http://blog.mgechev.com/2014/02/19/create-https-tls-ssl-application-with-express-nodejs/

Deployment:

You will need to create a node project and add the dependencies to your node project and configure the package,json accordingly.
Further you will need to create and add the HTTPS certificate to the service, for this it is advisable to read up on the HTTPS resource blog post
by Minko Gechev here - http://blog.mgechev.com/2014/02/19/create-https-tls-ssl-application-with-express-nodejs/

Note *** your request body should contain the following fields.

Token: From Firebase session
uid: From Firebase session

Happy Coding :)
