Include JS files using function from other JS file in Node

Question

I have been trying this stuff a lot but I am unable to get around with this stuff. I have 2 JS files, add.js and console.js.

add.js

module.exports = {
    add: function add(a,b){
        return a+b;
    }
};

console.js

module.exports = {
    debug: function debug(a,b){
        console.log(add(a,b));
    }
};

A part of app.js code

app.js

var add = require('./add').add;
var debug = require('./console');
console.log(debug.debug(3,4));

This is throwing me an error in console. "add is not defined" referencing the add of console.log(add(a,b)) in console.js

So, in general is there a way where we can write all the requires in one place (in order) and the things work automatically. For example, we do the same in javascript.

<script src="add.js"/>
<script src="console.js"/>

And the thing works. But how to do the same stuff in Node JS.

Answer 1

If you want to use add function in console.js file, you should require add.js file in console js file. Error says about add function which you have used in console.js file.
