Summary

ng-command lets you write commands which can only execute once whilst executing and also if canExecute is met.

Example

var app = angular.module('commandLab', ['ng-command'])
		.controller('CommandExampleCtrl', ['$command', '$scope', '$timeout',
			function ($command, $scope, $timeout) {
					
			var self = this;
					
			self.saveCmd = $command($scope, save, canExecute);
 
			function save (){
				return $timeout( function() {
				console.log("save", "yay!");
				}, 2000);
			}
			
			function canExecute() {
				return !self.isBusy;
			}

<button class="btn" ng-disabled="!vm.saveCmd.canExecute" ng-click="vm.saveCmd.execute()">
