Can Spin support new WASI from golang 1.21.0?

[rts-gordon]

Hi there,

Golang has released new version 1.21.0 that support WASI preview 1, it is more powerful than Tinygo, you know Tinygo can't compile many go libraries. So is it possible that Spint support new WASI from golang 1.21.0? Thank you.

@adamreese any idea about this? It looks like the wasmimport directive might serve for Spin host APIs but I think we noted a limitation with exporting trigger entry points - am I remembering correctly?

There was a blocker but I don't remember either. I haven't done any testing with the new go wasi support recently. Now that go has released support it's worth looking into.

I did some investigation and @itowlson was correct. Go version 1.21.1 adds the go:wasmimport but go:wasmexport isn't implemented yet. golang/go#42372
