Does this run inside a webcontainer?

[davidoort]

I'm wondering if I can run the client inside a proxy running in Stackblitz' webcontainers?

I'm not sure. Apparently webcontainers are implemented using WASM which is fine for JavaScript runtime but I have no idea how they implement native APIs, e.g. Node.js "tls" module 🤷

The issue I was running into when testing was the following:

TypeError: n.consume is not a function
    at ServerHttp2Session.setupHandle (builtins.ddb8d84d.js:122:11072)
    at new Http2Session (builtins.ddb8d84d.js:122:12905)

    at MessagePort._0x295eef (blitz.1b4252dd.js:19:299323)

which seems to point to an issue/limitation with node:http2. I guess this is strictly necessary for h2tunnel to work?

Thanks for posting the stack trace, that's useful. It seems that this runtime reimplements Node.js APIs on top of browser APIs which might be easy enough for fetch or simple HTTP servers but not practical for low-level networking APIs that h2tunnel requires. Furthermore it's proprietary so there's no way to look under the hood.

So I guess the answer to your question is sadly no, this runtime is not supported by h2tunnel :(
