BrowserFS.InMemory is undefined error in Firefox

[christislord12]

On first load of a pygbag project in Firefox it gives a BrowserFS.InMemory error. After reloading the page twice, the error does not happen and the project loads. This error does not occur in Safari or Opera.

yeah can confirm it is happening on Firefox but also appears to be happening on ios with safari

[long term decision] is to drop BrowserFS and use Panda3D vfs instead. There's no drop-in replacement for it i can see right now ( zipfs+overlayfs ) so not worth the work.

If anyone find something close please drop a note. Basically BrowserFS is a Node FS emulator ( with added complexity) like the one emscripten provides

They are moving to https://github.com/browser-fs
and now i don't even know how to load emscripten fs now ( it there's still any)

Javascript bundlers world seems as simple as python packaging so help very welcome here.

Hi @pmp-p and @christislord12, I'm the maintainer of BrowserFS. BrowserFS has been deprecated. Please see the notice in the readme at https://github.com/jvilk/browserfs for more info.

Would you be interested in updating your project to use the updated fork, ZenFS?

Support for Emscripten is pending on DefinitelyTyped#69218.

I would be very interested if support for overlayfs emscripten/WASM-OPFS is coming. If not i cannot justify time to make the switch :(

currently pygbag only use : zipfs + overlayed memfs

the next move would be to get user file persistence > 5 MiB for distributed applications otherwise localStorage still does the job.

@pmp-p,

OPFS is already available with the WebAccess backend, provided as part of @zenfs/dom. As I mentioned before, I'm waiting for the PR to merge before releasing the Emscripten backend. I expect it to be released one to two weeks after the PR is merged.
