Yes, npm is in path. From all directories I can execute npm/node 
(--version)
and receive a valid result.
I can execute npm start within folder "js" in both consoles, git 
bash and windows cmd.
There it works fine.

On windows cmd which is not a known command. On git bash I 
receive as result:
/c/Program Files/nodejs/npm

Kind regards
