Other options for Separate task

Parse File Names : Sync return

const ImageParser = require('./ImageParser');

console.log(ImageParser.parseFileName('./img_dest/', 'arrowNext@3x.png', 1)); // ./img_dest/arrow_next.png
console.log(ImageParser.parseFileName('./img_dest/', 'arrowNext@3x.png', 2)); // ./img_dest/arrow_next@2x.png
console.log(ImageParser.parseFileName('./img_dest/', 'arrowNext@3x.png', 3)); // ./img_dest/arrow_next@3x.png

Get file name : Promise based

const ImageParser = require('./ImageParser');

ImageParser.getFiles('./img_src').then(files => console.log(files)); // arrowNext@3x.png, search@3x.png

Change Image : Promise based

const ImageParser = require('./ImageParser');
const options = { srcDir: './img_src/', destDir: './img_dest/', file: 'arrowNext@3x.png' color: { red: 0, green: 255, blue: 255 } };
ImageParser.changeImage(options).then(() => console.log('done'));

Compress Images : Promise based

const ImageParser = require('./ImageParser');
const options = { destDir: './img_dest/', compressionSize: '50' };
ImageParser.compressImages(options).then(() => console.log('done'));
