Sandboxed application file system #115

Closed hydroper closed 1 year ago

hydroper commented 1 year ago

Adobe AIR supports a file system API which allows a rich-internet application to access the app's self installation directory (files that ship with the rich-internet application) and the app's private data directory (similiar to cookies or local storage).

Is there something similiar for the web? I know it's possible to emulate at least the app's private data directory with indexedDB (there's inclusively a NPM package for this), but it's not efficient I think and anyway there's currently no way to access the app's installation directory.

User permission for writting large files to app-storage:

indexedDB, localStorage and cookies have a short file size limit. Could the browser ask the user if the RIA is allowed to use large size files for app-storage: file storage?

Closest to that is probably the origin private file system. It’s specified in the File System Living Standard.

That should cover app-storage:! But it seems the article doesn't cover about the file size limit. Is there a permission prompt to ask the user to allow large storage files?

File size limits are bound to the storage quota of a storage shelf.

On browsers which support it, https://wicg.github.io/file-system-access/ allows you to read/write files on the local file system (without being subject to the browser's quota limits), but it's not exactly a 1:1 replacement since it's not possible to pre-load access to any specific files (see https://github.com/WICG/file-system-access/issues/235 for example)
