Promise-aware MongoLab $resource for AngularJS

---

##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 significantly 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).

Examples

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

Usage instructions

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.all(function(projects){
     $scope.projects = projects;
  });
});

Documentation

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([options], successcb, errorcb)
  • Resource.query(criteriaObject,[options], successcb, errorcb)
  • Resource.getById(idString, successcb, errorcb)
  • Resource.getByIds(idsArray, successcb, errorcb)
  • Resource.count(criteriaObject, successcb, errorcb)
  • Resource.distinct(fieldName, criteriaObject, successcb, errorcb)
• on an instance level:
  • resource.$id()
  • resource.$save(successcb, errorcb)
  • resource.$update(successcb, errorcb)
  • resource.$saveOrUpdate(successcb, updateSuccesscb, errorcb, updateErrorcb)
  • resource.$remove(successcb, errorcb)

Resource all and query supported options:

• sort: ex Resource.all({ sort: {priority: 1} }, cb);
• limit: ex Resource.all({ limit: 10 }, cb);
• fields: { 1 - Includes field, 0 - excludes field } ex Resource.all({ fields: {name: 1, notes: 0} }, cb);
• skip: ex Resource.all({ skip: 10 }, cb);

Contributting

New contributions are always welcomed. Just open a pull request making sure that it contains tests, doc updates. Checked if the Travis-CI build is alright.
