Thanks for your question about NPM (Node Package Manager). We do not provide support in Spanish, so my apologies for any confusion with my English reply. NPM comes packaged with NodeJS. You can find more information here. Note that NodeJS can only be installed on a VPS or Dedicated Server if you are hosting your account with InMotion Hosting.
If you have any further questions or comments, please let us know.Kindest regards,Arnel C.
