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.

Sometimes a dependency added with ng add will add more than one package, typing npm uninstall lib1 lib2 could be error prone and slow, so just remove the not needed libraries from package.json and run npm i
