Once you have your list of objects {filename, content}, you need to add them to a zip instance:

either

let zip = new JSZip();
parts.forEach((p) => zip.file(p.filename, p.content));

or

let zip = parts.reduce((zip, p) => zip.file(p.filename, p.content), new JSZip());

Then, call generateAsync to generate a promise of the result:

zip.generateAsync({type:"nodebuffer"}).then(/* success callback */).catch(/* error callback */)
