Explainer https://github.com/whatwg/fs/blob/main/proposals/FileSystemObserver.md Specification https://github.com/whatwg/fs/pull/165 Design docs [Design Doc] File System Observer <https://docs.google.com/document/d/1d6YoPvk0rdNBQaZcoFP-V5u4CBjgahvmnVsZpbn0Gmo/edit?usp=sharing> Summary The FileSystemObserver interface notifies websites of changes to the file system. Sites observe changes to files and directories to which the user has previously granted permission, in the user's local device (as specified in WICG/file-system-access) or in the Bucket File System (as specified in whatwg/fs), and are notified of basic change info, such as the change type. Blink component Blink>Storage>FileSystem <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3EStorage%3EFileSystem%22> TAG review https://github.com/w3ctag/design-reviews/issues/868 TAG review status Issues addressed Origin Trial Name FileSystemObserver interface Chromium Trial Name FileSystemObserver Origin Trial documentation link https://github.com/whatwg/fs/blob/main/proposals/FileSystemObserver.md WebFeature UseCounter name kV8FileSystemObserver_Constructor RisksInteroperability and Compatibility Gecko: Positive (https://github.com/mozilla/standards-positions/issues/942) WebKit: No signal (https://github.com/WebKit/standards-positions/issues/291) Web developers: Strongly positive ( https://github.com/WICG/file-system-access/issues/72) Use case from Origin Trial: https://insiders.vscode.dev Security Sites are only able to observe a file or a directory which the user has granted permission to. WebView application risks Not enabled on WebView Debuggability New WebIDL interface and attributes are available on DevTools console. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? No. Desktop only. This feature relies on FileSystemHandle object from whatwg/fs, which was only available on desktop until M132 when it was shipped on Android. Future work remains to enable FileSystemObserver API on Android. Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?
