mls

Mozilla Location Service API wrapper for Node.js

The Mozilla Location Service (MLS) is an open service which lets devices determine their location based on network infrastructure like WiFi access points and cell towers. This network based location service complements satellite based navigation systems like A-GPS. Combined these two approaches are one of the foundations for enabling context aware applications.

API key

Please refer to their development documentation for further details on how to obtain an API key.

How to use

Geolocate

var Mls = require('mls');
 
mls = new Mls('API_KEY'); // if no API_KEY is provided, "test" will be used
 
data = {
  "wifiAccessPoints": [
    {"macAddress":"a2:86:02:e1:56:4c"},
    {"macAddress":"1b:d3:44:ea:9e:54"},
    {"macAddress":"d7:32:58:ba:8d:d0"},
    {"macAddress":"67:87:ea:fa:80:66"}
  ]
};
 
mls.geolocate(data, function(err, loc) {
  // loc = { location: { lat: -10.45, lng: -30.6667 }, accuracy: 50000 }
});
