Angular has come out with some amazing new features in version 6.0.0, especially in Angular-cli. Now, with Angular 6, you can easily update your old packages, create native web elements using Angular Elements, and many other things. Let’s take a look!

ng add

ng add is a new command in Angular-cli that helps you install and download new packages in your angular apps. It works the same as npm, but it doesn’t replace it.

ng update

ng update is a new Angular-cli command too. It’s used to update and upgrade your packages. It’s really helpful, for example, when you want to upgrade from Angular 5 to Angular 6, or any other package in your Angular app.
