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](https://rustdoc.swc.rs/swc/) and for most users, your entry point for using the library will be [parser](https://rustdoc.swc.rs/swc_ecma_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](https://swc.rs/docs/installation/).
