disable async-to-functin-generator in configuration

[ShayRubach]

Can the async to function generation process can be disabled in configuration?

I wish to maintain

(async () => {});

as it is, without having all of the

import regeneratorRuntime from "regenerator-runtime";
function asyncGeneratorStep(gen, resolve, reject, _next, _throw, key, arg) {
   . . .
}

code added at all.
If not, is there other way to override it? I tried impl fn async_to_generator() -> impl Fold + VisitMut { with an empty implementation in my .rs file but with no success (Rust beginner).

Thanks.

This is same as #2788. We don't have explicit way to opt out specific transforms, in opposite as a workaround you can target higher level then add other transforms as needed.

Hey and thanks for the quick reply. A few questions if I may: 😃
By targeting a higher level you mean setting my EsVersion higher? (I'm using EsVersion::Es2022)
And with that being said, can you please direct me on how to configure plugins/transforms for swc? I'm not using any conf file at the moment, just straight up including the needed swc crates using Cargo and using:: them on my main.rs.

[Edit] Found the .swcrc doc. Now I just need to figure out what to target and what transforms should I add instead, I guess?

I think I solved it using your suggestion.

let _gen = comp.process_js(
        &handler, 
        _trns, 
        &Options{
            config: Config{
                jsc: JscConfig {
                    target: Some(EsVersion::Es2022),
                    ..Default::default()
                },
                minify: false,
                ..Default::default()
            },
            is_module: IsModule::Bool(true),
            ..Default::default()
        }
        ).unwrap();

My issue was that I had the 2022 target in the parse_js and not in the process_js.
Thanks!
