Node JS - function not executed - node.js

Question

I have a module which i wrote myself. It contains 3 functions which i call as chained promises. The last one does not execute and i cannot figure out why.
The module geodata.js
require('use-strict');
var Promise = require('promise');
var NodeGeocoder = require('node-geocoder');
var mongoose = require('mongoose');
var User = require('../models/user');
var options = {
provider: 'google',
httpAdapter: 'https',
apiKey: 'AIzaSyA4v81WbNOMeRL7p911Mxr6PBZnidX0cIM',
formatter: null
};
module.exports = {
//*******************************************************
// Find user and return his adress (street + town)
//
//*******************************************************
findUser: function(username) {
return new Promise(function(resolve, reject) {
User.findOne({
'username': username
}, function(err, doc) {
if (!err) {
resolve(doc);
} else {
reject(err);
}
});
});
},
//*******************************************************
// Fetch geodata (latitude + longitude) to users record in
// the user collection.
//*******************************************************
fetchGeoData: function(userObj) {
return new Promise(function(resolve, reject) {
var geocoder = NodeGeocoder(options);
var adress = userObj.street + ' ' + userObj.town;
geocoder.geocode(adress, function(err, res) {
if (!err) {
var res2 = {
'username': userObj.username
}
console.log(res);
resolve([res, res2]);
} else {
reject(err);
}
});
});
},
//*******************************************************
// Fetch geodata (latitude + longitude) to users record in
// the user collection.
//*******************************************************
addGeoData: function(message) {
return new Promise(function(resolve, reject) {
User.findOne({
'username': message.username
}, function(err, doc) {
console.log(doc);
if (err) {
console.log(err);
reject(err);
}
if (!doc) {
console.log('User not found.');
reject('User not found.');
}
doc.longitude = String(message.longitude);
doc.latitude = String(message.latitude);
doc.save();
resolve(doc);
});
});
},
fixJSON: function(inpJSON) {
var strung = JSON.stringify(inpJSON);
obj = strung.substring(1, strung.length - 1);
return (JSON.parse(obj));
}
};
.. and here is the calling script:
require('use-strict');
var mongoose = require('mongoose');
var dbConfig = require('./db');
var geodata = require('./lib/geodata.js');
// Connect to DB
mongoose.connect(dbConfig.url, {
auth: {
authdb: "admin"
}
});
mongoose.set('debug', true);
geodata.findUser('jimmy').then(function(result) {
console.log('findUser() done');
return geodata.fetchGeoData(result);
}).then(function(result) {
console.log('fetchGeoData() done');
var res1Fixed = geodata.fixJSON(result[0]);
var params = {
username: result[1].username,
longitude: res1Fixed.longitude,
latitude: res1Fixed.latitude
}
console.log(params);
return geodata.addGeoData(params);
}).then(function(result) {
console.log('addGeoData() done');
});
mongoose.connection.close();
the execution stops after this line:
console.log('fetchGeoData() done');
and i can't figure out why?

Answer 1

If you are referring to mongoose.connection.close(); that is actually being run before your console.log('addGeoData() done');
Notice that mongoose.connection.close() is synchronous whereas the mongoose.findUser is asynchronous.
