ReferenceError: FileReader is not defined

Question

I'm using in my index.js file this:

const reader = new FileReader();

I have this index.js file imported to my index.html

<script src="index.js"></script>

If I open the index.html file in browser, everything works fine.

However, if I try to use node index.js or nodemon index.js command, I get an error.

ReferenceError: FileReader is not defined

I can see in the vscode IDE that Filereader is from 'lib.dom.d.ts' and if I type to chrome inspect console 'FileReader' I can see that it exists. It seems to be bundled with chrome.

Is there a way I could bundle this file to index.js so that I can run node index.js or nodemon index.js? Or am I approaching this the wrong way? Should I use some other package instead of FileReader? The purpose is to use the package in the browser to read a file.
