Webassembly Support for "File System Access API"

XMLWordPrintable

    • WebAssembly

      To access files in the operating system there is the new "File System Access API".

      It allows programs that run in browsers to open a file with the ability to rewrite it and access the contents of a directory.
      It allows applications in the browser to have functionalities that are similar to the desktop.

      Support for this API could be an interesting addition for QT Webassembly.

      The API is used by Chrome/Edge, but is not supported by Firefox and Safari for privacy reasons.
      You can see how it works at https://vscode.dev/
