Modules As our application grows, we need to consider the possibility of splitting it into different modules. It comes with it a lot of advantages, thus helping us to find the best way to test and evolve each module separately from the others and also to share each module with other projects. In this chapter, we are going to cover the following topics: • How to create modules • Recommended modules Creating modules By gaining an in-depth understanding of the underlying business inside our application, we can isolate each group of functionalities (which are correlated) into a separated module. In the case of our parking application, we can split it into three different modules: • UI: This module gives directives that could be used by other projects such as alert, accordion, modal, tab, and tooltip. • Search: The search engine we created to filter cars could also be separated as an individual library and reused in other places. • Parking: This is the parking application itself, with its own resources such as views, controllers, directives, filters, and services. First, we need to create each new module separately and then they need to be declared inside the parking application module such that they are available. www.it-ebooks.info
Modules The UI module The UI module will contain the directives that we created in Chapter 2, Creating Reusable Components with Directives. To create an isolated and easy-to-use module, we should consider placing the entire code inside a unique file. However, this is not the kind of task that you would want to perform manually, and the best way to achieve this is by concatenating the files together through a tool such as Grunt, which we are going to study in Chapter 8, Automating the Workflow, and will learn how to concatenate the files together. For now, let's start by creating our new module called ui in the app.js file, as follows: var ui = angular.module("ui", []); After that, we will declare each component separated in its own file. This will improve the maintainability of the module, facilitating the access to the components. The template is another aspect that we need to take care. In Chapter 2, Creating Reusable Components with Directives, we separated it from the directive's code. However, though we want to deliver this library in an easier format, it would be a good choice to embed its code within the component. There are plugins for Grunt, such as grunt-html-to-js that may perform this tough and boring job for us. Consider the following code snippet in the alertDirective.js file: ui.directive("alert", function () { return { restrict: 'E', scope: { topic: '@' }, replace: true, transclude: true, template: "" + "" + "{{topic}}" + "" + "" + "" + "" }; }); [ 116 ] www.it-ebooks.info
