Long answer: first, `fetch` is a runtime feature, and Boa is first and foremost an engine. So `boa_engine` -- the core project crate -- does not support `fetch` out of the box.
That being said, we do have a `boa_runtime` crate. This crate is not currently a full runtime, but it is a collection of runtime features that have been implemented and can be registered onto the context. `fetch` is one of the features that has an implementation completed in `boa_runtime`, and it does use reqwest if I'm remembering correctly. If you're interested to see some example code of registering features, you can look at our CLI code as an example :)
I immediately have use for this if y'all have async fetch support. I can use JavaScript as an extension language for our app.
I love how supremely easy it looks to embed in normal Rust apps without a complicated build script. That, to me, is a killer feature.
Really awesome work on this!
