Building Angular Applications for Production

• Optimize the Build: Use Angular CLI to get the production version of your app. This command will pack a production ready bundle which will include optimizations like minifying, removing unused code (tree shaking) and ahead of time compilation.

                        
                        ng build --prod
                        
                    

• Inspect the Build Output: Unlike web servers that use WSGI, which needs another separate process, Flask is programming directly to your operating system then inspected the dist folder to confirm that the built output is correct. The folder hereby enumerates all the content required to have your program running in a production environment.

• Testing: The first step to deploying your application securely is by checking out whether each component within the application functions as it is supposed to in a production environment.

Deploying Angular Applications to Various Hosting Platforms

Netlify:

• Sign up for a Netlify account and log in to the dashboard.
• Drag and drop the contents of your dist folder or connect your GitHub repository to automatically deploy changes.
• Configure settings such as custom domains, redirects, and environment variables.

Firebase:

• Install the Firebase CLI using npm.
• Initialize Firebase in your project directory using firebase init.
• Run ng build --prod to build your Angular application.
• Deploy your application to Firebase Hosting using firebase deploy.

AWS (Amazon Web Services):

• Host your Angular application on AWS S3 by creating a new bucket.
• Set up bucket policies to allow public access to your files.
• Upload the contents of your dist folder to the S3 bucket.
• Configure static website hosting in the AWS Management Console.

Other Hosting Platforms:

Several Linux hosting platforms can accommodate running Angular app among them GitHub pages, Heroku, Vercel, and Azure. While the deployment process may differ slightly based on the platform, yet in general it would be carried out in a certain sequence.

Continuous Deployment:

Such build and release pipelines may also be configured with your version control system (e.g., GitHub, GitLab) to automate the process of deployment every time changes are pushed to the production environment.

In regard to Angular application deployment, track the application performance and as soon as any issues evolve, rectify the issue. Continuously patch the application software to reflect the latest trends and incorporate new security checks.
