This module is a really simple wrapper around ZLib. A while back I needed to compress the body of a web-service request. At the time, I was trying understand promises and async/await functions and the compression libraries all seem to require callbacks to control the flow of code. I ended up wrapping the call to ZLib's inflate and deflate actions in an async function.
npm install async-zip
const asyncZip = require('async-zip');
const inputString = "The string to compress";
const compressedString = await asyncZip.asyncCompressString(inputString);
const deCompressedString = await asyncZip.asyncDecompressString(compressedString);
console.log(deCompressedString.toString());
