The most recent thing was the typing app where we had to change style if each character after user typed it. With long texts (10k of characters) performance of tree diffing was not acceptable (especially in Safari) so we replaced whole text component with manually managed DOM and were mutating nodes directly. I’ve been using React for quite some time (started with version 0.11 or something) and had to integrate quite a few libraries on my own (stuff like OpenLayers for maps, etc) and it also worked pretty well. Also made few apps that had only few widgets (search UI, calendar, etc). It usually worked quite well. Mixing React with non React is quite easy. You only need to encapsulate it - keep all non vdom stuff in one component and never escape single DOM node.
