Rust WASM Library Template

Write Rust code and compile to WASM for use on the web.

Based on wasm-pack-template and this guide.

Requirements

• Rust
• wasm-pack

Development

1. Install deps: cargo
2. Write code (or import it into) in lib.rs

Building

Build project using:

• General use: wasm-pack build
• AudioWorklet: wasm-pack build --target web

This generates a WASM build, and nice JS + TS glue files, inside the /pkg folder.

For the general use version you'll likely need to use a build plugin to handle the WASM, like vite-plugin-wasm for a Vite build system.

If building for AudioWorklet, make sure to add the --target web flag or you'll get errors about TextEncoder missing, or a global URL variable being undefined.

Using code

1. Build project (see above)
2. Go into build folder: cd pkg
3. Create a link to the module: yarn link
4. Go into another JS project and link the module: yarn link rust-wasm-audio
