Before you read

Node and Express apps run on a machine/computer not inside a browser. So you have to use npm to run those. Here's a detailed answer that explains everything. As you just started with backend, this might be new to you

Answer

I don't think browserify is the right tool to bundle a server side application. It's better to use esbuild.

Here's a good article I found that shows how to do so.
