We just started a new project and concluded on the (build) stack in just under five minutes. Only for that fact I will share it with the world:
Now, a little bit about the app, because that's the driver behind the choices. It's a web app, obviously, mostly content driven (previously known as 'website') and responsive to mobile devices. It's bilingual, must have the best possible ux experience and be very fast, even under high load. Also, if not most important, it must be very flexible and maintainable. This app is going to change a lot in many ways, in the near and not so near future.
We're going to be stuck with it for many years and for that reason we want it to fit like a glove.
