Im very thankful that the scaling issues are being talked about. But I’m really keen on how the folder structure scales with the project. I actually think that the way you lay out your files has an equal impact upon your thinking as the way you break code out into controllers and services etc. You only have to open some of the most widely used packages to see folders with tens of dozens of files. When a new dev arrives the folder structure provides little architectural insight into the operations of the application. Great piece enjoyed it thoroughly.
