Neutron ↗ is self-contained node & npm application made for quick prototyping and teaching.
It borrows ideas from Processing ↗ and tries to create similar novice and artist friendly environment.
Neutron is based on Electron ↗, so you get everything that Chrome and Node can give you! (Native packages are sadly not supported right now, Neutron ships with ones I use for workshops often: node-serialport, johnny-five and node-midi.)
Detailed info is on github ↗, you can also download ↗ it straight from there.
I've also made a longer write-up about ideas and process behind building this: building neutron
