Rspack 2.3 will use SWC Next for JavaScript parsing.
We plan to gradually migrate more of Rspack's internals to SWC Next and introduce a new swc-next-loader that supports custom transform plugins written in JavaScript.
SWC Next is here!
Today, customizing how your code is transformed often means using Babel plugins or writing Wasm plugins for SWC.
I believe the next generation of JS compilers should combine Rust's performance with the flexibility to write custom transform plugins in
Introducing SWC Next: the foundation for SWC’s next major version, built on a new architecture inspired by Yuku.
