Safari version prior to 10.1 can suffer from extremely poor flexbox
performance. The recommended
way to work around this issue (as used on mobile.twitter.com) is to set
display:block
on Views in your element hierarchy that you know don't need
flexbox layout.
Not all of the views present on iOS/Android are currently available on Web. We are very much interested in the community's feedback on the next set of modules and views.
Not all the modules or views for iOS/Android can be implemented on Web. In some
cases it will be necessary to use a Web counterpart or to guard the use of a
module with Platform.OS
(e.g. NativeModules
)
There are properties that do not work across all platforms. All web-specific
props are annotated with (web)
in the documentation.
There are some known issues in React Native where APIs could be made more
consistent between platforms. For example, React Native for Web includes
ActivityIndicator
and a horizontal ProgressBar
for Web use, in anticipation
of the convergence between the iOS and Android components in React Native.
