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.

MSRV of crates is currently `1.73`.

To update all SWC crates you use, you can run `curl https://raw.githubusercontent.com/swc-project/swc/main/scripts/update-all-swc-crates.sh | bash -s`. This script will update all dependencies to the latest version and run `cargo build` to ensure that everything works.
Note that you need

-   `jq`
-   `cargo upgrade`

command to run the script.

Supported Node Versions:

-   Node v10+ for usage
-   Node v20+ for development
