I can't point to any (GMail client side code must be pretty big), but I do have a 5K one that I work on daily and it's not a mess. This project is still very much in development and will grow with time. It's not 50k and it's for sure not a project with 20 devs but even this size was unthinkable earlier. I'm working on a backend in node to take advantage of Websockets.
