Usage

var CostExplorer = require('aws-cost-explorer');
var ce = CostExplorer();

ce.getMonthToDateCosts(null, function(err, data) {
    if (err) {
        console.log(err);
    } else {
        console.dir(data, { depth: null });
    }
});

Passing AWS Configuration Options

var config = { 
    apiVersion: '2017-10-25',
    accessKeyId : 'AKIAJVCSKEY3SAMPLE',
    secretAccessKey : 'yWKUsVwtaXnssdGBeEVGPSAMPLE9hZuz9SAMPLE',
    region : 'us-east-1'
}

var CostExplorer = require('aws-cost-explorer');
var ce = CostExplorer(config);

ce.getMonthToDateCosts(null, function(err, data) {
    if (err) {
        console.log(err);
    } else {
        console.dir(data, { depth: null });
    }
});

Automatic Configuration from /config/default.json file

aws-cost-explorer uses config module to automatically load aws config keys an values from _dirname/config folder

var CostExplorer = require('aws-cost-explorer');
var ce = CostExplorer();

ce.getMonthToDateCosts(null, function(err, data) {
    if (err) {
        console.log(err);
    } else {
        console.dir(data, { depth: null });
    }
});

Sample default.json file located in _dirname/config folder
