Flux-Mithril
The Flux overview video seemed convincing. It's a web app architecture that lets you ask "How did my app get into this state?" and always have a straightforward path to an answer. It turns out Mithril fits the architecture as well or better than React does, and for me mobile-friendliness is important so I really like Mithril's size.
