Sample text

The ng-app directive takes an optional argument, which is the name of the module to load during bootstrapping. module('notesApp', []); This example defines a module (note the empty array as the second argument), and then lets AngularJS bootstrap the module through the ng-app directive. Creating Our First Controller We saw how to create modules, but what do we do with them? So far, they have just been empty modules. Let’s now take a look at controllers. Controllers in AngularJS are our workhorse, the JavaScript functions that perform or trigger the majority of our UI-oriented work.

It happened automatically. • The HTML connects parts of the DOM to controllers, functions, and variables, and not the other way around. This is one of the core principles of AngularJS at play here. An AngularJS application is a data-driven app. We routinely say “The model is the truth” in an AngularJS appli‐ cation. What this means is that our whole aim in an AngularJS application should be to manipulate and modify the model (pure JavaScript), and let AngularJS do the heavy lifting of updating the UI accordingly.

The best part was that we were able to do that without writing a single line of JavaScript. The same application in pure JavaScript would require us to create listeners and jQuery DOM manipulators. We were able to do away with all of that. Conclusion | 13 We also went over the basic philosophies of AngularJS and some of its benefits and how it differs from existing solutions. In the next chapter, we become familiar with some of the most common pieces of AngularJS, such as common directives, working with con‐ trollers, and using services.
