I'll be doing a brief demo during my lightning talk at ReactConf -- livestreamed at ~5:45pm pacific time today at http://conf.reactjs.org/livestream.
Then earlier this year I tried RN. And yes, I struggled mightily at times with building/deploying/linking libraries, but when it came to the app it finally felt closer to the level of effort I put in building web stuff. And then I finally sent an app out the door with Camera integration and some pretty neat UI elements. All thanks to this.
RN has lowered the barrier to entry in such a way that I have a feeling my story is/will be incredibly common. CRNA is yet another great step in that direction, so on behalf of us mostly part-time devs, thanks a ton!
During 24 hours at a hackathon I was able to build an app that would show a live view of the camera, capture 5 frames a second to be analysed by an external api, overlay recognised food items on the screen, send it all off to the hello fresh api and display a list of recipes to the user that would use the most food items from their fridge.
The fact that I was able to accomplish all of this in 24 hours with no prior RN experience is just amazing to me.
