instead of .bat files, just run npm install and node app.js. Than go to your browser and open localhost:3000

Doesn't work, i get an error about some deprecation stuff. It tells me my stuff is outdated, but just downloaded today??

from npm Docs :

npm update -g will apply the update action to each globally installed package that is outdated -- that is, has a version that is different from wanted.

Locally stored npm packages can also be outdated. I guess this is your case, try updating your packages.
