Summary
Chrome 121 supports a
modeproperty on the options objects that can be specified as arguments toFileSystemFileHandle.createSyncAccessHandle()andFileSystemFileHandle.createWritable(). See the associated ChromeStatus entry.These features are not yet in the FileSystem API spec — see whatwg/fs#151 for the relevant PR. Consequently, I have marked these additions as
"standard_track": false, and will mark them as non-standard in the associated docs.See also the New Locking Scheme to Enable Multiple Readers and Writers explainer for more information on how it works.
