BREAKING CHANGE: Communication from webview to react-native has been completely rewritten. React-native-webview will not use or override window.postMessage anymore. Reasons behind these changes can be found throughout so many issues that it made sense to go that way.
Instead of using window.postMessage(data, *), please now use window.ReactNativeWebView.postMessage(data).
Side note: if you wish to keep compatibility with the old version when you upgrade, you can use the injectedJavascript prop to do that:
const injectedJavascript = `(function() {
window.postMessage = function(data) {
window.ReactNativeWebView.postMessage(data);
};
})()`;
Huge thanks to @jordansexton and @KoenLav!
Added a new cacheEnabled prop to toggle Android & iOS webview caching behavior.
BREAKING CHANGE: This change makes caching enabled by default when previously there was no caching behavior which may cause unexpected behaviour changes in your existing implementations.
Addresses #80.
Caveat: I am not an Android developer. This code comes from a fork of the original RN WebView that we have been using in production for some time, so all credit goes to @Oblongmana: https://github.com/Oblongmana/react-native-webview-file-upload-android.
Setting up a DownloadManager for the WebView is pretty straightforward, as is adding any known cookies to the request. Most of the complication comes from the requirement after SDK 23 to ask the user for the WRITE_EXTERNAL_STORAGE permission. Unfortunately there is no mechanism to suspend the download request until permission is resolved so this code stores off the request and sets up a listener that enqueues the download once permissions are resolved so the user experience is really nice.
I didn't see anything in the way of tests or documentation that needs to be added for this change, so let me know if I missed anything. Thanks!
Fixes#33
I could really use some help from an Android developer on this one, because I just "made it work", don't know how to "make it work good".
Some things that should be reviewed:
- [ ] validate Android 5.0 devices (my emulator work, but outputs some weird sounds; a Galaxy 4 I tested on crashes)
- [ ] validate Android 5.1 devices (emulator works, couldn't find a real device)
- [ ] how to handle File Extensions? (https://www.w3schools.com/tags/att_input_accept.asp)
I'm sure that there's more refactoring to be done, so any help and advice would be appreciated.
