Usage example below:

'use strict';

let emercoin = require('./emercoin').createConnection('username', 'userpass', '192.168.0.1');

emercoin.query('getinfo')
    .then(function(data) {
        console.log("\n", 'Wallet version: ', data.version);
    })
    .catch(function(e) {
        console.log("\n", 'We have error: ', e.message);
    });

emercoin.query('name_show', 'ssh:sv')
    .then(function(data){
        console.log("\n", data);
    })
    .catch(function(e){
        console.log("\n", 'We have error: ', e.message);
    });
