How could I call that function from the command line in nodejs?

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?

Hello @kartik,

In your db.js, export the init function. There are many ways, but for example:

module.exports.init = function () {
  console.log('hi');
};

Then call it like this, assuming your db.js is in the same directory as your command prompt:

node -e 'require("./db").init()'

To other readers, the OP's init function could have been called anything, it is not important, it is just the specific name used in the question.

Hope it helps!!
Thank you!!
