Creating standalone ESM-based Node.js scripts on Unix and Windows

Approach:

  1. The file starts with shell code.
  2. That code uses Node.js to execute the file in ESM mode, after it removes the initial non-JavaScript lines.
    • Node.js does not currently have CLI flags for achieving what we do in this step. Therefore, we have to pipe to the node executable.

When editing this file, we want to use the JavaScript mode of our IDE or editor. Therefore, we try to “hide” the shell code from JavaScript as much as possible.
