Introduction

Welcome to the 16th tutorial of AngularJS! In this video, we will discuss views and routing in AngularJS applications. So far, we have only been working with a single view in our application. However, as the application becomes bigger, it is common to have different views for different pages such as a home view, list view, contact view, etc. AngularJS is primarily used for single-page applications, which means that when a user clicks on a link, the application requests a different view and dynamically injects it into the content area of the page. In this tutorial, we will learn how to create views, set up routing, and navigate between different views in AngularJS.

What are Views in AngularJS?

Views in AngularJS are the HTML templates that represent different sections or pages of a single-page application. Each view is associated with a specific URL route and is responsible for rendering the content of that route. Views in AngularJS can be created as separate HTML files and dynamically loaded into the application's content area based on the requested URL route.

Importance of Routing in AngularJS

Routing plays a crucial role in AngularJS as it allows us to navigate between different views without reloading the entire page. It enables us to create a seamless user experience by dynamically loading the relevant view based on the requested URL route. With routing, we can build complex applications with multiple views and easily switch between them just by changing the URL.

Creating View Files

To create views in AngularJS, we need to define separate HTML files for each view. These files will contain the necessary HTML code to render the content of the respective view. We can organize these view files in a separate directory, such as the "views" directory, to keep the project structure clean and maintainable.

Setting up Routing in AngularJS

To set up routing in AngularJS, we need to configure the routes that map the requested URL routes to the corresponding views. This can be done using the routing module in AngularJS. Before we can use the routing module, we need to include it as a dependency in our AngularJS application. We also need to link the routing module file using a script tag in our HTML file.

Injecting Dependencies for Routing

Since the routing module is a separate library in AngularJS, we need to inject its dependency into our application. This is done by including the "ngRoute" module as a dependency when creating the main module of our AngularJS application. By injecting this dependency, we can use the functionality provided by the routing module in our application.

Configuring Routes

Once we have set up the required dependencies, we can configure the routes in our AngularJS application. This involves defining the URL routes and specifying the corresponding views and controllers for each route. We can use the "config" method of the main module to set up the routes. In the configuration function, we use the "routeProvider" object to define the routes and their associated properties.

Using ng-view Directive

To indicate where the views should be injected in our HTML page, we use the "ng-view" directive provided by AngularJS. This directive acts as a placeholder for the dynamic views and is usually placed in the main content area of the page. By adding the "ng-view" directive to a tag, we inform AngularJS to insert the requested view into that tag when the corresponding URL route is accessed.

Understanding URL Parameters in Routes

In addition to static URL routes, AngularJS also allows us to define routes with dynamic parameters. These parameters can be extracted from the URL and used to customize the content of the view. By using URL parameters, we can create more flexible and personalized views in our application.

Clean URLs in AngularJS

By default, AngularJS uses the hash symbol ("#") in the URL to handle routing. However, for better SEO and user experience, it is recommended to use clean URLs without the hash symbol. AngularJS provides a way to configure clean URLs using the HTML5 mode. By enabling HTML5 mode, we can remove the hash symbol from the URLs and make them more user-friendly.

Conclusion

In this tutorial, we have learned about views and routing in AngularJS. We have seen how views represent different sections or pages of a single-page application and how routing allows us to navigate between these views seamlessly. By setting up routing, we can dynamically load views based on the requested URL route, creating a smoother user experience. We have also discussed the importance of injecting dependencies, configuring routes, and using the ng-view directive in AngularJS. Furthermore, we have explored URL parameters and clean URLs in AngularJS. With this knowledge, you can now confidently build complex AngularJS applications with multiple views and efficient routing.
