Angular ResourceFactory

Angular ResourceFactory is an AngularJS library that extends the capabilities of ngResource in various ways. The main features include a resource store for holding changes on resource instances and related resource instances to commit them at once, and an advanced resource caching.

Note: This library is for AngularJS 1.x only!

Dependencies

Angular ResourceFactory depends on AngularJS 1.x.

Installation

• Via npm: npm install --save angular-resource-factory
• Via git: git clone [email protected]:beachmachine/angular-resource-factory.git

Examples

RESTful service definition

In the following example we assume a RESTful endpoint that gives us the total of results via the count attribute and the actual data in the results attribute in the list call. Each object has an ID on the pk attribute, holds its own URL on the url attribute and also has some dates as creation_date and last_modification_date that we want to handle as Moment.js objects.

To make things a bit clearer, this is the list call result of the RESTful API endpoint:

{
  "count": 2,
  "results": [
    {
      "pk": 1,
      "url": "http://example.api/member/1/",
      "creation_date": "2017-01-11T06:00:00Z",
      "last_modification_date": "2017-01-12T08:00:00Z",
      "name": "Example Member 1"
    },
    {
      "pk": 2,
      "url": "http://example.api/member/2/",
      "creation_date": "2017-01-11T06:00:00Z",
      "last_modification_date": "2017-01-12T08:00:00Z",
      "name": "Example Member 2"
    }
  ]
}

Whereas this is the result of a detail call:

{
  "pk": 2,
  "url": "http://example.api/member/2/",
  "creation_date": "2017-01-11T06:00:00Z",
  "last_modification_date": "2017-01-12T08:00:00Z",
  "name": "Example Member 2"
}

Our service definition may look like this:

var module = angular.module('services');

module.factory('MemberResourceService',
    function (ResourceFactoryService) {
        return ResourceFactoryService('MemberResourceService', 'http://example.api/member/:pk/', {
            dataAttr: 'results',
            queryTotalAttr: 'count',
            pkAttr: 'pk',
            urlAttr: 'url',

            /**
             * Converts the dates to moment objects.
             * @param obj
             * @return {*}
             */
            toInternal: function (obj) {
                // no transformation needed if given object is false
                if (!obj) {
                    return obj;
                }

                obj.creation_date = obj.creation_date ? moment(obj.creation_date) : null;
                obj.last_modification_date = obj.last_modification_date ? moment(obj.last_modification_date) : null;

                return obj;
            },

            /**
             * Converts the moment dates to strings.
             * @param obj
             * @return {*}
             */
            fromInternal: function (obj) {
                // no transformation needed if given object is false
                if (!obj) {
                    return obj;
                }

                obj.creation_date = obj.creation_date ? moment(obj.creation_date).toJSON() : null;
                obj.last_modification_date = obj.last_modification_date ? moment(obj.last_modification_date).toJSON() : null;

                return obj;
            }
        });
    }
);
