Developing with AngularJS - Part III: Services

This is the 3rd article in a series on my experience developing with AngularJS. I used AngularJS for several months to create a "My Dashboard" feature for a client and learned a whole bunch of Angular goodness along the way. For previous articles, please see Part I: The Basics and Part II: Dialogs and Data.

Angular offers several ways to interact with data from the server. The easiest way is to use the $resource factory, which lets you interact with RESTful server-side data sources. When we started the My Dashboard project, we were hoping to interact with a REST API, but soon found out that it didn't have all the data we needed. Rather than loading the page and then making another request to get its data, we decided to embed the JSON in the page. For communication back to the server, we used our tried-and-true Ajax solution: DWR.

In Angular-speak, services are singletons that carry out specific tasks common to web apps. In other words, they're any $name object that can be injected into a controller or directive. However, as a Java Developer, I tend to think of services as objects that communicate with the server. Angular's documentation on Creating Services shows you various options for registering services. I used the angular.Module api method.

Developing with AngularJS - Part II: Dialogs and Data

A couple of days ago, I wrote an article on how I started developing with AngularJS. I used AngularJS for several months to develop a "My Dashboard" feature for a client's product and learned a whole bunch of stuff along the way.

This article provides an overview of how I changed some of My Dashboard's features to use Angular instead of jQuery. After finishing the prototype work in January, we started moving bits and pieces into the main application. We kept the same file names for our Angular-related files and copied them into the project.

All these files are packaged up into a dashboard.js file that's included at the bottom of our Dashboard page. While our prototype used jQuery 1.9 and jQuery UI 1.10, the application's codebase used jQuery 1.7.1 and jQuery UI 1.8.3. Luckily, this didn't present a problem as everything continued to work as expected.

Around this time, we also had many discussions with the Product Team about charts. Since Highcharts required we purchase a license, we took at look at AnyChart, which we were already using. We were able to get AnyChart to work with our existing chart directive with minimal changes. Most changes were in the JSON itself.

We committed the first pass (with sample data still hard-coded) in mid-February.

Developing with AngularJS - Part I: The Basics

There's many, many different introductions to AngularJS available on the internet. This article is not another introduction, but rather a story about my learning experience. It all started way back in January of this year. I was working as a UI Architecture Consultant at Taleo/Oracle, my client for the last 21 months. My gig there ended last month, but they agreed to let me publish a series of articles about the knowledge I gained.

Project Background

The Director of Product Management had been working on the concepts for a new project - codenamed "Visual MyView". Below is a mockup he created for our kickoff meeting on January 4th.

From his original email about the above mockup:

I started the initial layout with static HTML and CSS and had a wireframe to show by mid January.

By the end of January, we'd renamed the project to My Dashboard and had a working prototype using CoolClock and moment.js for the clock in the top right, AngularJS to display widget data, jQuery UI for drag-n-drop of rows and widgets, Bootstrap's Carousel for holding charts and Highcharts for rendering charts.
