##Introduction

This repository hosts a Mongolab $resource-like adapter for AngularJS. It is based on $http and is working with promises.

This is a small wrapper around the AngularJS $http that makes setting up and working with MongoLab easy. It has an interface very similar to $resource but works with promises. It significient reduces the amount of boilerplate code one needs to write when interacting with MongoDB / MongoLab (especially around URLs handling, resource objects creation and identifiers handling).

To see it in action check this plunker: (http://embed.plnkr.co/Y8sg4V).

Firstly you need to include both AngularJS and the mongolabResourceHttp.js script from this repository (see examples above for the exact URLs).

Then, you need to configure 2 parameters:

• MongoLab key (API_KEY)
• database name (DB_NAME)

Configuration parameters needs to be specified in a constant MONGOLAB_CONFIG on an application's module:

var app = angular.module('app', ['mongolabResourceHttp']);

app.constant('MONGOLAB_CONFIG',{API_KEY:'[your key goes here]', DB_NAME:'angularjs'});

Then, creating new resources is very, very easy and boils down to calling $mongolabResource with a MongoDB collection name:

app.factory('Project', function ($mongolabResourceHttp) {
    return $mongolabResourceHttp('projects');
});

As soon as the above is done you are ready to inject and use a freshly created resource in your services and controllers:

app.controller('AppController', function ($scope, Project) {
  Project.query(function(projects){
     $scope.projects = projects;
  });
});

Since this $resource-like implementation is based on $http it accepts callbacks in its methods calls and returns a promise. Each resource created with the $mongolabResourceHttp will be equipped with the following methods:

• on the class level:
  • Resource.all(successcb, errorcb)
  • Resource.query(criteriaObject, successcb, errorcb)
  • Resource.getById(idString, successcb, errorcb)
  • Resource.getByIds(idsArray, successcb, errorcb)
• on an instance level:
  • resource.$id()
  • resource.$save(successcb, errorcb)
  • resource.$update(successcb, errorcb)
  • resource.$saveOrUpdate(successcb, errorcb, updateSuccesscb, updateErrorcb)
  • resource.$remove(successcb, errorcb)
