The easiest way to save a file locally is to craft a link for the download that when clicked returns the file bytes with the Content-Disposition set to be attachment as specified in https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Disposition and the download attribute set on the anchor.

Javascript cannot save files to a users computer**
