Angularjs Logo


AngularJS is a Javascript application framework for extending HTML beyond it’s original capabilities.

Modern websites typically require to take static markup further as user interaction brings changes to content, and AngularJS aims to make this easier for developers to set up.

Web Development can be considerably quicker when using pre-established methods and where common web components are used, it seems sensible to take advantage of what has gone for, then spending your own time customising it to meet your specific needs. AngularJS offers and is already widespread in Web Development circles.

AngularJS has many tools ready to use out of the box, with just a few lines of code. There are also many opportunities to create your own tools too, or perhaps include others from an extensive and helpful community who may well have come up with something close to what you need already.

AngularJS with Bootstrap can offer you a great combination of fast interface builds with dynamic data, perfect for a prototype that you need without spending too much development time. Any code that you come up with can also then be used in development too as it will be of a higher quality, from set methods used by others.

A further ideal of AngularJS is to create individual components, similar to Bootstrap’s front-end UI setup, and then pass these components between projects where there is a need for them. This should reduce maintenance as websites develop over time.

Frequent web development tasks have been catered for here, with items such as forms, for example, being quick to set up and being customisable without delving into core Javascript files. Validation for instance is handled directly from the markup in a similar way to how HTML5 is now capable of.

You will see from the code snippets used here that various attributes will be all you need to start of your initial AngularJS web app, you can even then create your own HTML5 tags if you need to without much extra work. As will most Javascript Application Frameworks, the only way to decide on whether AngularJS is the one for you is to use it for your next project.

Set Active Area for your AngularJS Application

Add “ng-app” to the containing element of your application. In most cases this will be the html tag, where you want to run AngularJS throughout.


Automatically update lists of data

Use “ng-repeat” to output all objects of one collection, with the output updating when new data is added. This would be ideal for a shopping basket, for example, where you might want to remove items without a page refresh.

Dynamically Generated Content from JSON file

The example below comes directly from one the tutorials on the official AngularJS website and gives a great example of how you might go about constructing a dynamic list directly from a data source. For simple examples it is best to use JSON, but in the real world you may well be retrieving data from a more complex backend.

The ng-repeat continues from the previous example, and here there would be several different attributes for each item in the JSON file, e.g. name, snippet and imageURL. This could perhaps be a small product list with small, introductory information on key products.

The new items used in this example which are worth noting are the built-in filter and orderBy functions which are used here alongside ng-repeat. You will see in the search and sort by options above the unordered list as to where the corresponding items sit for filtering and ordering the content, with Angular then doing all the rest for you.
