 ## Notes

 The components used in the render benchmarks are simple enough to be
-implemented by multiple styling libraries. The implementations are not
-equivalent but are useful for framing the relative performance of
-`react-native-web` against these tests.
-
-The implementations are not equivalent. For example, the `react-native-web`
-implementation of `View` does more than just styling. The
-`react-native-web/lite` variant implements a minimal `View` that allows for a
-more direct comparison with the `css-modules` baseline.
+implemented by multiple UI or style libraries. The implementations are not
+equivalent in functionality.

Nicolas Gallagher	68068f8cb6	[fix] support React Native props in 'setNativeProps' React Native allows props like 'pointerEvents' to be set using 'setNativeProps'. Fix #392	2017-03-20 22:33:59 -07:00
Nicolas Gallagher	e05e2122d7	[fix] avoid setting empty style objects	2017-03-20 22:33:59 -07:00
Nicolas Gallagher	47dac44120	[fix] filter 'lineBreakMode' from Text props	2017-03-20 22:33:53 -07:00
Nicolas Gallagher	22af6894c2	Update jest	2017-03-20 22:18:50 -07:00
Nicolas Gallagher	458c534200	[change] improve button accessibility and styling 1. If no 'accessibilityRole' is set, fallback to looking for 'button' role in the equivalent native props. This helps improve accessibility of button-like components authored without the web platform in mind. 2. Ensure button context is properly inherited. 3. Add 'appearance:none' to DOM button elements to enable better styling support in Safari Fix #378	2017-03-20 14:50:01 -07:00

Nicolas Gallagher	976320916e	[change] move bridge code into createDOMElement Moves event normalization and the ResponderEventPlugin injection from 'View' to 'createDOMElement'. The 'react-native-web/lite' variant is removed from the performance directory as the implementation is not substantially different. Micro-optimizations to marginally narrow the performance gap to css-modules.	2017-03-19 15:19:26 -07:00
Nicolas Gallagher	808790505e	[change] onLayout improvements 1. Fires when window resizes 2. Guards against nodes being unmounted Fix #397 Ref #60	2017-03-19 13:29:47 -07:00
