Extend ImageLoader functionality to be able to work with image sources containing headers We preserve the existing strategy that works with image.src for cases where source is just an uri with no headers When sources contain headers we make a fetch request and then render a local url for the downloaded blob (URL.createObjectURL) Fix #1019 Fix #2268 Close #2442
If the Image component is rendered with a `null` source, and consecutively updated with actual source url that was already loaded, it would fail to pick up the change - `state` would be `IDLE` for a brief moment and this would cause a small flicker when the image renders Let's always start from IDLE state, and update `shouldDisplaySource` condition to be based on `ImageLoader.has` cache or not Fix #2492

I would like to use the preview in my application as I would love to take advantage of the Image http headers. I'll admit im not well versed in git... how would I reference this instead of 0.19? 0.20-dev doesnt appear to change anything |

Notes
StyleSheet runtime for compilers
babel-plugin-react-native-webhas a new optionlegacy, which istrueby default. Set it tofalseand the plugin will no longer rewrite any'react-native'paths, with the exception of theStyleSheetimport.The
StyleSheetimport is rewritten to[..]/StyleSheet/runtime.The runtime is only
StyleSheet()withoutcreate,compose,flatten, etc., support.The
legacy:falseoption should be used only if a built-time compiler is being used to extract styles to CSS, and either inline results or error the otherStyleSheetmethod calls React Native includes. The compiler output should follow the style object format described by the styleq runtime.This is an experiment to add a mechanism to exclude the runtime style compiler from builds. It's open to feedback and iteration.
