A comment on Exploring Goja: A Golang JavaScript Runtime.

I just dug through a lot of the issues and PRs in Goja, and eventually found that the grafana/k6 team recently forked Goja as Sobek [1], because the Goja dev has not been able to dedicate sufficient time to their PRs - namely ES Modules support [2], which was one of the only modern {ES6+) JS features outstanding [3]

So, Sobek seems to be the way forward...

I did see that. I'm going to let the fork simmer for awhile. I didn't require module support for my runtime. Since its meant to be very basic ETL runtime.

Fair enough! Though they're quite clearly a much more serious/focused/resourced team than the goja dev, and they've fully integrated it into the K6 codebase now. I expect it'll have a bright future.

Since you're doing ETL, did you consider something like Conduit, which is written in Golang and also allows for JS processing in the pipeline? Or is that overkill for what youre doing?

While I'm sure Goja is great for just JavaScript, using something like wazero allows your app to support more languages (anything that compiles to WASM) while keeping the benefits of CGO.

I've used Wazero myself on C++ -> WASM code but I'm sure you could use Emscripten or something to compile JavaScript to WASM.
