React Starter Kit:

There’s so much going on with it, it’s hard to know where to start.

Passport:
It looks like by default it uses a Facebook login via Passport.

Sequelize:
The starter kit uses sequelize to do DB operations with an RDBS.

It uses a service worker to cache static assets, that’s kind of interesting:
