Explainer https://github.com/whatwg/fs/blob/main/proposals/MultipleReadersWriters.md Summary Currently, only one FileSystemSyncAccessHandle may be open at a time per file, preventing an origin from reading the same file from multiple tabs easily. Conversely, multiple FileSystemWritableFileStreams can be simultaneously open, letting multiple writers clobber each other. We are prototyping new “create” modes for FileSystemSyncAccessHandle and FileSystemWritableFileStream that allow opening either multiple readers/writers or an exclusive writer to a file entry, depending on the application's use case. ``` handle.createSyncAccessHandle({ mode: 'read-only' }); handle.createWritable({ mode: 'exclusive' }); ``` Blink component Blink>Storage>FileSystem <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EStorage%3EFileSystem> TAG review https://github.com/w3ctag/design-reviews/issues/845 TAG review status Pending Risks Interoperability and Compatibility Gecko: Positive with regards to allowing multiple FileSystemSyncAccessHandles. Stance on the shape of this specific proposal is not yet known. <https://github.com/whatwg/fs/issues/34> WebKit: Positive with regards to allowing multiple read-only FileSystemSyncAccessHandles. Stance on the shape of this specific proposal is not yet known. <https://github.com/whatwg/fs/issues/34> Web developers: Positive (https://github.com/whatwg/fs/issues/34) Other signals: Emscripten plans to utilize multiple readers and writers for performance improvement, and sites using Emscripten will be able to take advantage of this integration. Debuggability N/A Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? Yes Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?
