NodeJS_scripts

If we want to use NodeJS as a scripting language without going to the trouble of setting up an NPM-based development environment, we can use the following architecture.

#!/usr/bin/env node

const process = require("process");

const actualScript = (firstParam, secondParam) => {
  // Do something
};

if (require.main === module) {
  const [, param1, param2] = process.argv;
  actualScript(param1, param2).catch(console.error);
}

Basically we have a function that contains the main actions of the script. This is then invoked within main in the manner of a Bash or

This obviously requires the Node binary to be in your path and the script must be run with executable privileges.

The module check at the bottom which makes the script file invocable.
