I had previous experience with QuickJS - respectively using the rquickjs crate (awesome project) - so my approach was first asserting whether it was possible to run a Wasmtime binary that both executes the JS code and handles HTTP requests and responses.

Then, the second part which was really important to me, was figuring out if I could find a way to embed the developer's JS code within the worker without requiring them to install Cargo. (thanks to Wizer it's possible, love it).

Once I had those two, the rest was basically execution (not saying it was straightforward though ;)

I was also a bit lucky: at the same time as I was developing it, Rolldown announced the version 1 of their standalone crate. So it was the perfect timing to use it as well.

As for StackBlitz WebContainers, I actually don't know much about it. They run in the browser as I understand, so fundamentally different but, feature wise I'm sure this project is way more mature and therefore offers way more features.

Awesome, thanks for detailing the thought flow and choices that led you here. I chose not to go the QuickJS route for performance reasons but I think it's a solid choice depending on the use case.

Yes, runs entirely in the browser, while this is a hosted product. StackBlitz technology is really good but it is closed source.

Yeah I was surprised by this when I opened their website.

Your setup - Rust/WASM kernel + Service worker - sounds really sweet. If already public, please do share the link, else looking forward to your launch!

Will do, thanks!
