Contributing to wasm-bindgen

This section contains instructions on how to get this project up and running for development. You may want to browse the [unpublished guide documentation] for wasm-bindgen as well as it may have more up-to-date information.


  1. Rust. Install Rust. Once Rust is installed, run

    rustup target add wasm32-unknown-unknown
  1. The tests for this project use Node. Make sure you have node >= 10 installed, as that is when WebAssembly support was introduced. Install Node.

Code Formatting

Although formatting rules are not mandatory, it is encouraged to run cargo fmt (rustfmt) with its default rules within a PR to maintain a more organized code base. If necessary, a PR with a single commit that formats the entire project is also welcome.
