Usage

The main export returns a function that needs to be called to expose the object of helpers.

Get all helpers

var helpers = require('handlebars-helpers')();
//=&gt; returns object with all (130+) helpers

Get a specific helper collection

Helper collections are exposed as getters, so only the helpers you want will be required and loaded.

var helpers = require('handlebars-helpers');
var math = helpers.math();
//=&gt; only the `math` helpers

var helpers = require('handlebars-helpers');
var array = helpers.array();
//=&gt; only the `collections` helpers

Get multiple helpers collections

Helper collections are exposed as getters, so only the helpers you want will be required and loaded.

var helpers = require('handlebars-helpers')(['math', 'string']);
//=&gt; only the `math` and `string` helpers

Optionally pass your own handlebars

var handlebars = require('handlebars');
var helpers = require('handlebars-helpers')({
  handlebars: handlebars
});

// or for a specific collection
var math = helpers.math({
  handlebars: handlebars
});
