Dan: working on React.. CDT integration was great
… there is no way for a library to tell if user is recording or not, we're afraid of wasting memory
… we're calling clearmarks/measures all the time, but it means we can't harvest it later
… our main target is CDT
… i.e. in dev mode
an example -> https://facebook.github.io/react/docs/optimizing-performance.html#profiling-components-with-chrome-timeline
a) sounds like there is a need for API in devtools for in "record mode"
b) you should log some data to performance timeline.. perhaps with lower fidelity
Nic: we monitor React today, we look at routechange events
Dan: we expose UT for every component in dev mode
