``var {google} = require('googleapis'); var MESSAGING_SCOPE = "https://www.googleapis.com/auth/firebase.messaging";` `var SCOPES = [MESSAGING_SCOPE];`

var http = require('http')

function getAccessToken(){ return new Promise(function(resolve, reject){ var key = require("./ServiceAccountKey.json"); var jwtClient = new google.auth.JWT( key.client_email, null, key.private_key, SCOPES, null ); jwtClient.authorize(function(err, tokens){ if(err){ reject(err); return; } resolve(tokens.access_token+":"+tokens.expiry_date); }); }); }

var server = http.createServer(function(req, res){

 `getAccessToken().then(function(access_token){`

     `res.end(access_token);`

 `});`

});

server.listen(3000, function(){ console.log("Server started"); });
