Module emscripten 

Running on the Web with Emscripten

At the moment wgpu has one example meant to run under Emscripten: wgpu-hal/examples/raw-gles.rs.

In the workspace’s top directory, build the example as follows:

cargo clean
EMCC_CFLAGS="-g -s ERROR_ON_UNDEFINED_SYMBOLS=0 --no-entry -s FULL_ES3=1" \
    cargo build --example raw-gles --target wasm32-unknown-emscripten --features gles,emscripten,webgl

Then copy the HTML page that loads the compiled example into the target directory alongside the WebAssembly:

cp wgpu-hal/examples/raw-gles.em.html target/wasm32-unknown-emscripten/debug/examples/

Finally, start an HTTP server publishing the contents of that directory:

cd target/wasm32-unknown-emscripten/debug/examples/
python -m http.server

Then visit localhost:8000/ in your browser.

If you get other, more interesting examples working with Emscripten, please update this page!
