How to remove package using Angular CLI?

You can use npm uninstall <package-name> will remove it from your package.json file and from node_modules.

If you do ng help command, you will see that there is no ng remove/delete supported command. So, basically you cannot revert the ng add behavior yet.

It's an open issue #900 on GitHub, unfortunately at this point of time it looks that in Angular CLI there's nothing like ng remove/rm/..., only using npm uninstall DEPENDENCY is the current workaround.
