Run function in script from command line (Node JS)

Question

I\'m writing a web app in Node. If I\'ve got some JS file db.js with a function init in it how could I call that function from the command line?

Answer 1

Sometimes you want to run a function via CLI, sometimes you want to require it from another module. Here's how to do both.

// file to run
const runMe = () => {}
if (require.main === module) {
  runMe()
} 
module.exports = runMe
