Declare multiple module.exports in Node.js

Question

Declare multiple module.exports in Node.js

What I'm trying to achieve is to create one module that contains multiple functions in it.

module.js:

module.exports = function(firstParam) { console.log("You did it"); },
module.exports = function(secondParam) { console.log("Yes you did it"); }, 
// This may contain more functions

main.js:

var foo = require('module.js')(firstParam);
var bar = require('module.js')(secondParam);

The problem I have is that the firstParam is an object type and the secondParam is a URL string, but when I have that it always complains that the type is wrong.

How can I declare multiple module.exports in this case?

node.js
module

Answer 1

You can do something like:

module.exports = {
    method: function() {},
    otherMethod: function() {}
}

Or even just:

exports.method = function() {};
exports.otherMethod = function() {};

Answer 2

You can write a function that manually delegates between the other functions:

module.exports = function(arg) {
    if(arg instanceof String) {
         return doStringThing.apply(this, arguments);
    }else{
         return doObjectThing.apply(this, arguments);
    }
};

This is just for my reference as what I was trying to achieve is can be accomplish by this.

In the module.js

We can do something like this

    module.exports = function ( firstArg, secondArg ) {

    function firstFunction ( ) { ... }

    function  secondFunction ( ) { ... }

    function thirdFunction ( ) { ... }

      return { firstFunction: firstFunction, secondFunction: secondFunction,
 thirdFunction: thirdFunction };

    }

In the main.js

var name = require('module')(firstArg, secondArg);
