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

simple way:

let's say you have db.js file in a helpers directory in project structure.

now go inside helpers directory and go to node console

 helpers $ node

2) require db.js file

> var db = require("./db")

3) call your function (in your case its init())

> db.init()

hope this helps
