Is there a way to read file metadata using node.js
提问by bbeny
Does any one know of a way that I can read file metadata using node.js? For example, I want to read the 'comment' attribute on the 'details' tab of a jpeg file (on a Windows machine). See image below to understand what it is I am trying to read from the file's metadata.
