Description
Library to get location from mobile networks information (MCC, MNC, LAC,
Cell ID) using Google, Yandex, OpenCellId, Mylnikov and Mozilla Location
Services.
In this new version library was completely rewritten in pure JavaScript with
Promises and no external dependencies.
All services now work fine, but for some of them you need API keys.
Installation
You can install it with this command:
npm install bscoords
Usage
First require library:
const bscoords = require('bscoords');
If you want to use OpenCellId, Mozilla Location Service or set custom socket
timeout, you should initialize library before using:
bscoords.init({
apikey_mylnikov : '',
apikey_opencellid: 'you should sign up on https://opencellid.org/ to get this',
apikey_mozilla : 'you should request it at Mozilla',
'timeout': 3000
});
Then perform requests the following way:
bs
.yandex(mcc, mnc, lac, cellid)
.then(coords => {
console.log(JSON.stringify(coords, null, 4));
})
.catch(err => console.log(err));
bs
.google(mcc, mnc, lac, cellid)
.then(coords => {
console.log(JSON.stringify(coords, null, 4));
})
.catch(err => console.log(err));
bs
.opencellid(mcc, mnc, lac, cellid)
.then(coords => {
console.log(JSON.stringify(coords, null, 4));
})
.catch(err => console.log(err));
bs
.mylnikov(mcc, mnc, lac, cellid)
.then(coords => {
console.log(JSON.stringify(coords, null, 4));
})
.catch(err => console.log(err));
bs
.mozilla(mcc, mnc, lac, cellid)
.then(coords => {
console.log(JSON.stringify(coords, null, 4));
})
.catch(err => console.log(err));
bs
.cell2gps(mcc, mnc, lac, cellid)
.then(coords => {
console.log(JSON.stringify(coords, null, 4));
})
.catch(err => console.log(err));
You can also use one request to get coordinates from all services at once:
bs
.all(mcc, mnc, lac, cellid)
.then(coords => {
console.log(`All:`);
console.log(JSON.stringify(coords, null, 4));
})
.catch(err => {
console.log(`All ERROR:`);
console.log(err);
});
Or you can explicitly choose services to get coordinates from:
bs
.all(mcc, mnc, lac, cellid, ['yandex', 'google', 'mylnikov', 'opencellid', 'mozilla', 'cell2gps'])
.then(coords => {
console.log(`All:`);
console.log(JSON.stringify(coords, null, 4));
})
.catch(err => {
console.log(`All ERROR:`);
console.log(err);
});
You can also specify weight of every service to calculate average coordinates
with respect of services accuracy.
In this example Yandex and Google are the most significant services in
average coordinates calculation, Mylnikov.org is the least significant and
Mozilla Location Service doesn't affects average coordinates at all:
bs
.all(mcc, mnc, lac, cellid,
['yandex', 'google', 'mylnikov', 'opencellid', 'mozilla', 'cell2gps'],
{yandex: 1, google: 1, mylnikov: 0.2, opencellid: 0.5, mozilla: 0, cell2gps: 1})
.then(coords => {
console.log(`All:`);
console.log(JSON.stringify(coords, null, 4));
})
.catch(err => {
console.log(`All ERROR:`);
console.log(err);
});
Result will be object with the following structure:
{
"average": {
"lat": 54.54321,
"lon": 23.12345
},
"yandex": {
"lat": 54.54321,
"lon": 23.12345
},
"google": {
"lat": 54.54321,
"lon": 23.12345
},
"mylnikov": {
"lat": 54.54321,
"lon": 23.12345
},
"opencellid": null,
"mozilla": {
"lat": 54.54321,
"lon": 23.12345
},
"cell2gps": {
"lat": 54.54321,
"lon": 23.12345
}
}
