angular-q-limit Examples

dynamicClosureLimit.js

// This example uses a dynamic array of items, creating a promise for each and finally executing them via $q.limitAll with a maximum of 3 items running concurrently

// Assumes SomeModel is a promise based structure like $http or ngResource


var stuff = [ // Very big array of things to request // ];

$q.limitAll(3,
	stuff.map(function(item) {
		return SomeModel.get({id: item}).$promise;
	}),
});

limitAllExample.js

// This example runs 3 defined promise limited to 1 item of concurrency (yes you could just use .then().then().then() but thats not the point)

// Assumes SomeModel1-3 is a promise based structure like $http or ngResource

$q.limitAll(1, [
	function() {
		return SomeModel1.query().$promise
			.then(data => $scope.data1 = data);
	},
	function() {
		return SomeModel2.query().$promise
			.then(data => $scope.data2 = data);
	},
	function() {
		return SomeModel3.query().$promise
			.then(data => $scope.data3 = data);
	},
]).then(function() { // All done // }});
