React touch demos
This demo uses ReactHack to build a high-performance, lazy-loading 3d intertial touch app targeted at the iPhone 5. It really shows off what web technologies can do these days.
Software being used
- React JS library (so easy to use, and performance is great without even trying!)
- Zynga Scroller for touch gesture physics (not in repo)
Why target iPhone 5?
- I know the GPU perf characteristics
- Android touch event latency sucks vs iPhone
- I know the screen size so I can avoid image resizing
- Why is this cool? It performs well and has native-like interactions (as in you can partially open-close the left nav). To do this you need to animate every frame with JS (no CSS transitions or animations here!)
- Why doesn't it work without JS enabled? Because this is a JS tech demo. React does support server rendering so I could render to a static page with little to no code changes though.
- The markup isn't semantic! The semantic-ness can be improved for sure. But we should care less about semantic-ness and more about performance or else the web will die at the hands of native mobile SDKs.
- What's React got to do with it? React's one-way data binding is so performant that we can write the whole app declaratively. I don't think it's easy to do in other data binding frameworks.
