AngularJS: Tutorial: Part 4: Directive Example

In Part 1, we when over the basics on AngularJS. In Part 2, we when over AngularJS and Charts. In Part 3, we when over common mistakes when developing using AngularJS.  In this part of the tutorial, I wish to share with you a small directive I am building. I apologize in advance if you see my code a little messy. I have a shortage of free time so I built this in a hurry. I am not including the back-end such as PHP, MySQL, and REST using JSON. That would be part of another tutorial.

Lets begin with this draft of project. The idea is to use JSON as the model that will indicate the view to use a template which itself use the UI feature called accordion in a nested way to display all the work experience I have:

Lets begin with the JSON, workExperience.json:

Please notice that in your database the information would not be organized in this way. I am doing in purposed because I don’t wish to give a solid idea on how the database looks like:

Second, lets go to our template, accord.html:

<uib-accordion close-others="true">

	<div ng-repeat="companies in datasource" ng-init="companiesIndex = $index">
		
		<div ng-repeat="(a, b) in companies">

			<uib-accordion-group is-open="status.openMain[companiesIndex]" >

				<uib-accordion-heading>
					{{'{\{::a}\}'}} <!-- Company Name -->
					<i class="pull-right glyphicon" 
					   ng-class="{'glyphicon-chevron-down': status.openMain[companiesIndex], 'glyphicon-chevron-right': !status.openMain[companiesIndex]}">
					</i>
				</uib-accordion-heading>

				<div ng-repeat="(c, d) in b">					
					<p ng-bind-html="c"></p> <!-- Company Description -->
					
					<uib-accordion close-others="false">

						<div ng-repeat="(e, f) in d">
														
							<div ng-repeat="(g,h) in f">
					
								<uib-accordion-group is-open="status.openSub[e]" >

									<uib-accordion-heading>		
										{{'{\{::g}\}'}}	<!-- Project Name -->							
										<i class="pull-right glyphicon" 
										    ng-class="{'glyphicon-chevron-down': status.openSub[e], 'glyphicon-chevron-right': !status.openSub[e]}"></i>
									</uib-accordion-heading>
									<p ng-bind-html="h"></p> 	<!-- Project Description -->						

								</uib-accordion-group>								
							
							</div>
						</div>

					</uib-accordion>
				</div>	
			
			</uib-accordion-group>
		</div>

	</div>

</uib-accordion>

In accord, we are using “ng-bind-html” which allows us to include HTML in our JSON to be displayed.
You need to have the angular-sanitize.js library in order to use it. Also, notice I am using one-time binding “::” indicator, in this way we reduce the number for $watchers being used.

Next, is the motor of our directive and controller, index.js:

(function () {
	'use strict';

	var accMod = angular.module('acc', ['ngAnimate', 'ui.bootstrap']);
	
	accMod.directive('accord', function () {

	    var scope = {
	    	datasource: '='
	    };

    	return {    		
	        templateUrl: 'accord.html',	     
	        scope: scope
    	};

	});


	var mod = angular.module('ui.bootstrap.app', ['acc', 'ngSanitize']);

	mod.controller('workExperienceController', ['$scope', '$http', function($scope, $http){

		$http.get('workExperience.json')
			.then(function(res){
				$scope.workExperienceDataSource = res.data;
		});

	}]);




	
}());

Short and to the point. I created a module where I administrate the directive related with accordion UI feature, and another module which takes care of all the modules of my application. By doing this, I can reuse code that later I inject in other projects. Also, I can little by little build my own angular library.

Here is the main page, index.html:

<!doctype html>
<html ng-app="ui.bootstrap.app">
	<head>
		<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.7/angular.js"></script>
		<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.7/angular-animate.js"></script>
		<script src="https://code.angularjs.org/1.2.0-rc.3/angular-sanitize.js"></script>
		<script src="http://angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.14.3.js"></script>
		<script src="index.js"></script>
		<link href="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet">
	</head>
	<body>

		<div>

			<p><b>WORK EXPERIENCE</b></p>
			<div ng-controller="workExperienceController">
				<div accord datasource="workExperienceDataSource"></div>
			</div>

		</div>

	</body>
</html>

In the future, I will create a directive that will iterate through all the JSON and build nested accordions automatically.
For now, this JSON will create a 2 level nested accordion as displayed below.

Finally, the working example:

AngularJS: Tutorial: Part 1

Background

AngularJS is an open source framework, designed for the creation of enhanced web applications, created by Miško Hevery at Brat Tech LLC, and maintained by Google plus a community of developers and corporations. It implements most of the concepts behind all new standards on web components and model driven views. This framework is in the category of data binding frameworks.

You can create single page applications in which the page doesn’t required to reload, by using XML, JSON plus AJAX to fetch data, and without using server-side rendering. You follow a simple concept called Model-View-Controller in which the data taken care by the model (database, file, etc.), the view take cares of everything related with the interaction with the user, and the controller takes care of the communication between the model and the view. Another way to describe this concept is the idea that the model updates the view, the view display the information to the user, the user interact with the controller via the view, and the controller manipulates the model.

MVC-ConceptIt is important to indicate that AngularJS uses data binding which means that there is a synchronization between the model an the user interface. That, it implements routing, a way to handle updates by using URL hash fragments. Finally, by using templates and model, it allows for the dynamically creating and update of HTML.

Type your name: <input ng-model="name" type="text" />
Hello, {{'{{name}\}'}}
</body>
</html>

 

Example 2:

		$controllerProvider.allowGlobals();
	});
	
	function NameController($scope){

	});
</script>
</head>

Living in the “Industial Era” in the 21st Century

Today, I am planning to begin my route into AngularJS. Currently, I am searching for a job and due the fact that I do not know AngularJS have closed to me many great opportunities. It did not matter if I am a nice guy, if I am a fast learned, or if I was in charged of developing and maintaining critical systems that cost and/or generated thousands of dollars at my previous jobs. My lack of knowing a framework such as AngularJS have being the major reason for being rejected. At least, that is the reason I was told.

We still behaving like in the “Industrial Era”, even do we are leaving the “Information Era” and getting into the era of “What to do With so Much Information Era”. In this new era, you are required to learn, re-learn and even forget faster than never before. The technology you are using today, can be easily replaced by something else, quite fast. Programming languages, libraries, and frameworks can be learned thanks for the available tools such as Internet, books, and so for. How to do clean, reusable, and expandable code is different matter. That takes time, experimentation, practice, and experience.

If you are interested in learning on how to recognize in which era you are and which era you are getting into, read “The Third Wave” by Alvin Toffler, author of “Powershift“, “Future Shock“, and “Revolutionary Wealth“. I would advice to take attention on how the author identify each era, instead of just reading for knowledge gathering.

My learning process have always being to get involved into some major project. There is nothing better than real life experiences. They beat any tutorial you can find. You have to learn fast and do thing right from the beginning because people depend on you and you should try to be always a professional. However, I do not have a real life project right now and money is running out. Therefore, I will have to do with tutorials and perhaps some fake project that force me to cover everything needed to be learn.

Lucky for me there is always an image that give me hope:
never-give-up
