angularjs - MEAN Stack Error when calling two different api's routes at the same time -

having issues angularjs, mongoose or mongolab. if make 2 api calls different api route @ same time, data won't load. got working waiting each call finish (with promise) before making next call. way me doesn't sound me because if of call fail, rest of page won't load. there anyway can avoid waiting? here example of got right now.

angularjs controllers working code:

// profiles         homeservices.getprofile()             .then(function (result) {                 $scope.profiles = result.data;                  // portfolios                 homeservices.getportfolios()                     .then(function (result) {                         $scope.portfolios = result.data;                      }, function (error) {                         console.log(error.statustext);                     });              }, function (error) {                 console.log(error.statustext);             }); 

api's:

// profile api api.get('/profiles', function (req, res) {     // model schema     var profile = require('../models/profile');      // create db connection     var db = mongoose.createconnection(config.server.db);      // set model     var model = db.model('profile', profile, 'profiles');      // find videos     model.find({}, function (err, data) {          if (err) {             res.status(500).send(err);         } else {             res.status(200).send(data);         }          // disconnect db         mongoose.disconnect();     }); });  // portfolio api api.get('/portfolios', function (req, res) {     // model schema     var portfolio = require('../models/portfolio');      // create db connection     var db = mongoose.createconnection(config.server.db);      // set model     var model = db.model('portfolio', portfolio, 'portfolios');      // find videos     model.find({}, function (err, data) {          if (err) {             console.log(err);             res.status(500).send(err);         } else {             res.status(200).send(data);         }          // disconnect db         mongoose.disconnect();     });  }); 

here want able do:

        // profiles         homeservices.getprofile()             .then(function (result) {                 $scope.profiles = result.data;                }, function (error) {                 console.log(error.statustext);             });          // portfolios         homeservices.getportfolios()             .then(function (result) {                 $scope.portfolios = result.data;               }, function (error) {                 console.log(error.statustext);             }); 

here error mongolab:

{ [mongoerror: server mongolab.com:59661 sockets closed] name: 'mongoerror', message: 'server db... sockets closed' } 

update: removing mongoose.disconnect(); works needed. don't want create connection @ each endpoint.

i believe error comes constant create/close of mongo connection. sustain single connection on multiple endpoints:

var portfolio = require("../models/portfolio") var profile = require("../models/profile") var db = mongoose.connect(config.server.db)  db.connection.once("connected", function() {      api.get("/profiles", function(req, res) { ... });      api.get("/portfolios", function(req, res) { ... }); }); 

you using createconnection() used creating connections multiple databases. judging these endpoints, don't need that. i'd use connect() instead. recommend reading more connections here

as aside, defined portfolio , profile @ top of file, since may repeated on different endpoints.
