There is a build tool that makes it really easy to compile and bundle Rust activities. The finished bundle will be located in build/activity
.
Alternatively you can also use webpack with the wasm-pack plugin. See the webpack example.
# Install the build tool
cargo install activity-build
# Set env vars
export CLIENT_ID=1234567890
# Run it in the directory where your `Cargo.toml` is located
activity-build --release
