Deploying an application holds extreme importance: all our hard work of developing will show up once the site is alive.

Deploying Angular applications is pretty straightforward if you generate the required compiled source code, and, with latest versions of Angular, the AOT compilation defaults to any build generated with the --prod meta flag. We learned about the importance of AOT and how critical it is to have it for overall application performance and security. We learned to deploy a standalone Angular application and also composite Angular applications with multiple projects, libraries, and components.

Finally, we learned about deploying our Angular application to GitHub Pages using the official angular-cli-ghpages package.

That brings us to the conclusion of our last chapter in this book. We have come a long way in our learning journey, from understanding the basics of the TypeScript language to learning how to build our Angular applications by implementing the Angular framework's components, routing systems, directives, pipes, forms, backend services, and much more.

We also learned about implementing various CSS frameworks, such as Bootstrap, Angular Material, and Flex layout with our Angular applications. Additionally, we learned how to design and make our application's UI much more appealing and interactive. 

We explored unit testing using the Jasmine and Karma frameworks, which ensures that our applications are well-tested and are rock-solid implementations.

We have also implemented the user authentication mechanism using Auth0 and Firebase as part of learning Angular Advanced topics. Finally, we covered the deployment of Angular applications.

That is a 360-degree overview of all aspects of application development using the Angular framework. We hope you now feel empowered to build world-class products using the Angular framework. 

We wish you all the best and look forward to hearing about your success stories soon.

Good luck! Onward and upward.
