Pattern for defining angularjs filter

filters.js

define(['angular'], function (ng) {
  'use strict';
  return ng.module('app.filters', []);
});

ngFilterAdapter.js

define([
  // Umbrella module
  './filters',
  // If you create a new filter and want to use in angular
  // Please add it to the list below, in alphabetical order.
  './sample-filter'
],
function(filters){
//---------------------------------------------------
// BEGIN code for this module
//---------------------------------------------------

var args = Array.prototype.slice.call(arguments, 1);

// For each of the filters listed above
args.forEach(function(filter){
  // Create angular filter with
  // filter name = filter.name
  // filter function = filter.filter
  filters.filter(filter.name, function(){
    return filter.filter;
  });
});

return filters;

//---------------------------------------------------
// END code for this module
//---------------------------------------------------
});

sample-filter.js

define([
],
function () {
  'use strict';
//---------------------------------------------------
// BEGIN code for this filter
//---------------------------------------------------

return{
  name: 'sampleFilter',
  filter: function(input, params) {
    return input + ' *sample*';
  }
};

//---------------------------------------------------
// END code for this filter
//---------------------------------------------------
});
