    Description

      Currently, support for using a disk cache in QtDeclarative is disabled. This is due to the filesystem sandbox in which WebAssembly lives, in that it does not have normal access to the filesystem.

      This is to research if it is feasible to use the disk caching, through emscripten FS javascript if needed.

      https://kripken.github.io/emscripten-site/docs/api_reference/Filesystem-API.html

      Persistent file system access involves synching files to the sandbox, which can be slow.
