RuntimeError: can't start new thread - Only when running in WASM

At a glance

The community member has an app they would like to deploy using html-wasm, but they are encountering an error when trying to start a thread. They have provided a link to their code on GitHub. The community members in the comments indicate that threading is not currently supported in WASM, and that additional support is needed in the stack before this functionality can be enabled.

I've got an app that I'd like to deploy via html-wasm, but I'm getting an error when I try to start a thread.

You can see the code here - https://github.com/FredHutch/differential-expression-viewer/blob/main/app.py

Is threading supported in WASM or is that not possible?

Ah shoot, the AI assistant says that this is not supported at all

Yea that is correct. It's a few layers in the stack that need to add support before we can.
