I'm looking to get back into fronted development using react, but I have never built something large with it before. There's a ton of great content out there, but as soon as what you're building gets more complex than a TODO- or Tic Tac Toe App, you're stuck.

Do you know of a good introduction/tutorial/demo on how all the pieces fit together in a real-world application? I'm thinking about something like railstutorial.org, but for frontend/react.
