Install the Angular CLI from NPM, remembering to include the -g to indicate that you wish to install it globally. This will allow you to create applications outside the scope of any existing application.
With the instillation complete, verify the instillation by running ng--version. Now you know you have a proper instillation of the Angular CLI.
To create an application, type ng to activate the Angular CLI, new to indicate that you wish to create a new application, and then the name of the application you wish to create. In this case, I will use sample as the name of the application.
By creating a new application, we've also created a new directory with the same name of the application. From that directory, you can run ng-serve to compile the application and run it.
Take note that the application is running on local host port 4200.
With the application now being served, you can navigate to local host port 4200 in your browser to see the application running. The Angular CLI's ng-serve provides a live reload experience. Make a change to the app component in your editor, save the file, and see the changes reflected directly in your browser.
