Demo project for building WebAssembly projects using Rust.

Detailed documentation is provided in the docs directories and at woofwoofinc.github.io/webassembly.

Developing

The project build stack uses the Rust development tools. Install these on your system with rustup if they are not already available.

Emscripten is needed to compile .wasm files. Install it using:

EMSCRIPTEN_VERSION=1.37.21
wget https://s3.amazonaws.com/mozilla-games/emscripten/releases/emsdk-portable.tar.gz
tar xzf emsdk-portable.tar.gz
cd emsdk-portable

emsdk update
emsdk install emscripten-${EMSCRIPTEN_VERSION}
emsdk install clang-e${EMSCRIPTEN_VERSION}-64bit

emsdk activate emscripten-${EMSCRIPTEN_VERSION}
emsdk activate clang-e${EMSCRIPTEN_VERSION}-64bit

Then add the location of the emsdk-portable directory, emsdk-portable/clang/e$EMSCRIPTEN_VERSION_64bit and emsdk-portable/emscripten/$EMSCRIPTEN_VERSION to your PATH.

Finally install the Rust WebAssembly target architecture.

rustup target add wasm32-unknown-emscripten

The project build stack also uses Node.js, the Yarn package manager, and the Webpack module bundler. Install these on your system if they are not already available.

It is also useful to have the Webpack development server installed.

A rkt container build script is included in the project repository and provides an installation which can be used to build the project also. See the description on building and running the container in the Development Tools Container section of the documentation for more information.

For macOS, RktMachine provides a CoreOS VM which supports developing using the rkt container system.

For the Webpack build, first install Literacy and the other project dependencies using Yarn.

$ yarn

Then run the Webpack development server to build and serve a test site.

$ webpack-dev-server -d

CAUTION: See the documentation if developing on the included rkt container or using RktMachine. Extra options are needed for the development server to be reachable from the host machine.

The test site can be accessed via a browser on localhost:8080.

To test the Rust project, use:

$ cargo test
