Rust-based platform for the Web

Make the web (development) faster.

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. Without such guarantee, using SWC would be too hard as SWC is a large, modular project and typically you have to use many modules.

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