Tsconfig JSX = "preserve" Support

[geospatialweb]

Describe the feature

As I understand it, SWC only supports the React options available in tsconfig JSX - which therefore excludes Vue JSX that I'm using. Thus no support for SWC tsconfig emitDecoratorMetadata = true which is not supported by Vite esbuild - hence my desire to switch to SWC (plus Rust performance gains) but I cannot because I am not using React. Any thoughts or possibilities?

This also blocks the use of SWC (and maybe Rspack families?) in building Solid libraries since Solid libraries need to ship files with JSX preserved.

I agree—I’m very disappointed that neither the SWC team nor the SolidJS team seems to be addressing this. I’m stuck on Webpack, and while I tried Vite, it was difficult to integrate with my codebase. Right now I don’t feel like I have a solid toolchain to use Solid with SWC or anything that offers similar performance.

@NunoCruzSW #10691 has been merged to the dev branch. When this change is released (probably SWC v2), you will be able to preserve Solid JSX in Rspack or Rslib.
