Create a file object or Blob

Question

How can we create a file object or a blob object in Node js? The object required should be same as we get while uploading a file from a form in HTML.

Why would you want to? They're designed for the client environment and severely limited as a result. — T.J. Crowder

I am trying to test a API which lets me upload a file but needs a file object or a blob object. I want to test is using node js but could not figure out a way to create a file or blob object — Vipul

You're probably better off using a headless browser implementation like PhantomJS (if it has the File API, I don't know that that specific one does). — T.J. Crowder

an uploaded file is just binary data, right? whatever object it was wrapped in is not relevant once the data is submitted from the browser to the server. On the server, assuming you're file is getting stored into a Buffer, well then, you can also fill a Buffer with binary data via fs.read or `fs.readSync' and use that — user2524973

You can't directly create objects from the File API, because that's an API designed for the client side and implemented by browsers.

If you wanted to, you could implement those same objects yourself (the API is fully documented, of course), but it would probably make more sense to use NodeJS's file system API instead.
