Build

The default (and only) target for this example is wasm32-freestanding-musl.

The latest zig version used to build this project is:

$ zig version
0.13.0

To build the wasm module to /public/bin/astro-checkerboard.wasm, run:

$ zig build -p public

$ ls ./public/bin
astro-checkerboard.wasm

$ wc -c ./public/bin/astro-checkerboard.wasm
555 ./public/bin/astro-checkerboard.wasm

Note: build.zig specifies various wasm-ld parameters. For example, it sets the initial memory size and maximum size to be 2 pages, where each page consists of 64kB. Use the --verbose flag to see the complete list of flags the build uses.
