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](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
