@swc/core NPM | npm.io

SWC (stands for Speedy Web Compiler) is a super-fast TypeScript / JavaScript compiler written in Rust. It's a library for Rust and JavaScript at the same time. If you are using SWC from Rust, see rustdoc and for most users, your entry point for using the library will be parser.

Also, SWC tries to ensure that

If you select the latest version of each crates, it will work

for rust users.

MSRV of crates is currently nightly, but we will support stable rustc again in the future.

If you are using SWC from JavaScript, please refer to docs on the website.
