I have a Ubuntu 16.04 server with a Drupal 8.4 site

I want to install Node.js for my site.

1) I connected to my server with root and I entered the following command at the root of my server :

root@vps000000:~# curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
root@vps000000:~# apt-get install -y nodejs

The installation went well.

2) I'm installing now drupal-node.js :

root@vps000000~# npm install drupal-node.js

The problem is that I was wrong location for installing the module drupal-node.js. In effect it should be in the drupal site folder.

I executed the following command to uninstall it :

root@vps000000~# npm uninstall drupal-node.js

The module is uninstalled, but the node_modules folder and the package-lock.json file are still there :

root@vps000000:~# ls
dead.letter drupal.phar installer_la_cle.sh node_modules package-lock.json

Here is the content of the directory node_modules :

I know how to install drupal-node.js in my drupal site. How to uninstall it completely from my root directory ?

Should he just do rm -r ?
