tarawasm is a CLI toolkit for building WebAssembly components. It supports multiple guest languages and can be used directly or via an official Docker image. Key features include initialization, binding generation, component building, artifact cleanup, and a strip command for reducing WASM binary size.
Highlights
Guest language support for Python, Go, Rust, JavaScript, and C/C++
Docker-based workflow with the published image mandeser0/tarawasm
Core commands: init, bind, build, clean, all, and strip
Config handling via the Config dataclass stored in tarawasm.json
Strip command to remove custom sections from a WebAssembly binary
Examples for each language under examples/ demonstrating initialization, binding, building, and execution
Docker Image
Pull the official Docker image from Docker Hub:
docker pull mandeser0/tarawasm:latest
Using Docker avoids the need to install toolchains locally. You can run the CLI via:
alias tarawasm='docker run --rm -v "$PWD":/work -w /work mandeser0/tarawasm'This image is automatically built and published through the repository’s GitHub Actions workflow.
Testing
A pytest suite exercises each language example and validates that the strip command reduces binary size
