Landon James (Jan 22 2024 at 22:45): Landon James (Jan 22 2024 at 22:45):I have some components that use the wasi:http shim to make network calls. I initially assumed these would be totally blocking, but when looking through the @bytecodealliance/preview2-shim code I noticed the lib/io/worker-* files that seem to imply some of the wasi:* backed IO is happening in a Worker and is not blocking.
Curious if this is all piped in with jco's functionality by default or if I would need to do some special configuration to use the worker-* versions of the shims? I've been exploring instantiating/calling my components in a Worker thread to avoid blocking, but if it is already non-blocking that would be great!
Guy Bedford (Jan 22 2024 at 22:54):@Landon James yes we have a "non-blocking" polls implementation but this is only currently supported in Node.js. Supporting the browser is the next priority now that this implementation has been completed, but that work will be a little while still.
Landon James (Jan 22 2024 at 23:05):Ahh great to hear, I am only looking to support Node at the moment. Do I need to do anything to enable that? I see that the nodejs/http.js implementation is only pulling in the worker-io stuff at the moment, so not sure if that is fully non-blocking yet? Happy to contribute some work here once I figure out what needs to be done since this would be more helpful than wrapping all my own stuff in Workers.
Guy Bedford (Jan 22 2024 at 23:30):oh, yeah it should all work out in Node.js if you use the default transpile options - http is fully supported
