Recently I’ve been trying to create a SharePoint 2013 app using AngularJS and angularui-bootstrap.

It’s been going well thanks to Jeremy Thake’s (@jthake) original demo.

But I wanted more! More than just access to the local site, I wanted access to the web, but I wanted to do it in the right AngularJs way, using the service so later when I figure out how to do DI testing I can, using promises too, which of course SharePoint doesn’t return in a way we can use in AngularJS.

So this code snippet (not complete app) will give you a clue on a way of doing it, there may be a better way to do this in AngularJS Im no expert, I see references to module.Factory calls in other examples, but I’m sticking to Jeremy’s starter code for now.

This example uses UK police data, details of the license are here http://www.nationalarchives.gov.uk/doc/open-government-licence/version/2

'use strict';
var myApp = angular.module("myApp", []);

function myAppCtrl($scope, $myDataService) {
	$scope.getPoliceClick = function () {

		//Whoops, edited this line as it was wrong from original post
		var promise = $myDataService.getPolice($scope);
		promise.then(
			//Success callback, check the status = 200 and go mad
			function (response) {
				//...
			},
			//Epic Fail callback
			function (response) {
				//..
			}
		);
	};
};

//this method signature is same as Jeremy"s thats why the $http is there, I use it for lists as well
//just not in this code sample
myApp.service("$myDataService) ", function ($q, $http) {
	this.getPolice = function ($scope) {
		var deferred = $q.defer();
		var context = SP.ClientContext.get_current();
		var request = new SP.WebRequestInfo();
		request.set_url("http://data.police.uk/api/bedfordshire/57");
			request.set_method("GET");
		// We need the response formatted as JSON.
		request.set_headers({
			"Accept": "application/json;odata=verbose"
		});
		var response = SP.WebProxy.invoke(context, request);
		context.executeQueryAsync(
			function () {
				//Notice the scope apply, because the async call is made from outside of angular
				//just resolving will not work
				$scope.$apply(deferred.resolve(response));
			},
			function () {
				$scope.$apply(deferred.reject(response));
			}
		);
		return deferred.promise;
	};
});
