Best way to structure helpers functions in NodeJS

Question

I am trying to build a set of utils for my NodeJS project. These helpers will include: text utils (like substringing, console logging etc.), and more specific helpers like p

Answer 1

You can see a utils library example with lodash.

Lodash is an utility lib like underscorejs. This library have file sustem structure like your.

It divides the functions in categories. Each category is a folder with an index.js file that includes into a namespace (literal object) each functions for that category!

Lodash/
   Objects/
       Function1.js
       Functions2.js
       ....
       Index.js
   Array/
       Function1.js
       ...
       Index.js

Then in your code you can do this:

var objectsUtils = require("lodash/objects");
var foreach = require("lodash/array/each");

You can create a similar file system structure in order to have more flexibility. You can require the entire lib, only one namespace or a single function.

This is better for performance, because you use only what you need and have a memory usage gain.
