Batch geolocate using Yandex geolocator

Readme.md

Use yandex geocode API to get data (json array of object) on set of input addresses in strings. Like http://geocode-maps.yandex.ru/1.x/?format=json&geocode=petach%20tikva&kind=locality&lang=en-US.

index.js

/* jshint strict: false */
/* global process, console, require */

var fs = require('fs');

var request = require('request');

var typeNeeded = process.argv[2] || 'locality';
var source = process.argv[3] || './payload.json';
var output = process.argv[4] || 'output.json';
var arrayOfNames = require(source);

var toDo = arrayOfNames.length,
    done = 0,
    resultSet = [];
console.log('Will take names in ', source, ' and search for ', typeNeeded, ' type in features');
console.log('result will be outputed to ', output);

function getListOfFeatures(body) {
    var result;
    try {
        result = body.response.GeoObjectCollection.featureMember;
    } catch (e) {
        console.log('Errored at ', body.response);
        result = [];
    }
    return result;
}

function getTypeOfFeature(feature) {
    return feature.GeoObject.metaDataProperty.GeocoderMetaData.kind;
}

function featureByType(feature) {
    return getTypeOfFeature(feature) === typeNeeded;
}
arrayOfNames.forEach(function(name) {
    var url = 'http://geocode-maps.yandex.ru/1.x/?format=json&geocode=%NAME%&kind=%TYPENEEDED%&lang=en-US'
        .replace('%NAME%', encodeURIComponent(name))
        .replace('%TYPENEEDED%', encodeURIComponent(typeNeeded));
    request(url, function(error, response, body) {
        done++;
        if (error) return console.error('Error occurred: ', error.message);
        if (!error & response.statusCode == 200) {
            resultSet = resultSet.concat(getListOfFeatures(JSON.parse(body)).filter(featureByType));
        }
        if (toDo == done) {
            fs.writeFile(output, JSON.stringify(resultSet, null, 2));
        }
    });
});
