Question

I have a problem in which i’m using a file to hold a list of modules and requiring this list in one call in my nodejs server. I want to use the modules in the list in a specific way.

modules.js –

Mods = {
  mymodule: require('./mymodule.js')
}

exports.f = function() {
  return Mods;
}

index.js –

f = require('./modules.js').f;

f().mymodule.echo("Hello World");

so instead of how i’m using f() now i want to put the name of the module i’m calling directly into the function so I can do things like this:

f = require('./modules.js').f;

f('mymodule').echo("Hello World");

I’ve tried a number of different experiments but can’t get it to work, is it possible to do this in javascript?

Well, if you do this:

var Mods = {
    mymodule: require('./mymodule.js');
}

module.exports = function( name ) {
    return Mods[name];
};

You can then do:

var f = require( "./modules.js"); //no .f required

f( "mymodule" ).echo( "Hello world");
