import { readFile, writeFile } from 'fs/promises';
import optimizePNG from "imagemin-most-optimized-png";

const options = {

	optipng: 3 
}

const optimze = async path => {
	const data = await readFile(path);
	const optimized = await optimizePNG(data, options);
	await writeFile("/path/to/dist/image.png", optimized);
} 

optimze("/path/to/source/image.png");
