AngularJS in Patterns (Part 3)

This publication aims to provide a more theoretical overview of some of the AngularJS components in order to show you how the things you are already familiar with (like different Object-Oriented Design Patterns) fit in the picture.

AngularJS in Patterns (Part 1). Overview of AngularJS

Thu, 08 May 2014 00:00:00 +0000

In this series of blog posts I’m going to cover the paper I’m writing at GitHub.

It aims to provide a bit more theoretical overview of some of the AngularJS components in order to show you how the things you are already familiar with (like different Object-Oriented Design Patterns) fit in the picture.

Part one includes only a high level overview of AngularJS, enjoy it.

AngularJS overview

AngularJS is JavaScript framework developed by Google. It intends to provide a solid base for the development of CRUD Single-Page Applications (SPA). SPA is a web application, which once loaded, does not require a full page reload when the user performs any actions with it. This means that all application resources (data, templates, scripts, styles) should be loaded with the initial request or better – the information and resources should be loaded on demand. Since most of the CRUD applications have common characteristics and requirements, AngularJS intends to provide the optimal set of them out-of-the-box. A few important features of AngularJS are:

Self-invoking functions in JavaScript (or Immediately Invoked Function Expressions)

Wed, 29 Aug 2012 00:00:00 +0000

There are a lot of interesting things in the syntax of JavaScript, one of which is the definition of self-executing (self-invoking) functions. Here’s how we can defined such function:

(function () {
  // body of the function
}());

The anonymous function above will be invoked right after it has been defined. The benefit of self-invoking functions is that they enable us to execute code once without cluttering the global namespace (without declaring any globals). For example, if we have a web page in which we want to attach event listeners to DOM elements and other initialization work, self-invoking functions would be the best tool for the job!
