For a somewhat more complete example which runs in browsers, check out my little pacman.zig toy project [0]. This is cheating a bit by using the Emscripten SDK as 'sysroot' (needed for the Emscripten headers to provide the glue to web APIs), and the Emscripten linker to create the additional html and js output file, but the actual code is all compiled with the Zig compiler to WASM, emcc is only used for linking.
The interesting part is that the platform abstraction is provided by the sokol C headers [1], with auto-generated Zig bindings [2]. It's interesting because the C headers use "Emscripten magic" (mainly embedding Javascript snippets in the C sources via the EM_JS() macro), and the Zig compiler is able to compile this (when it has access to the Emscripten headers).
It would be nice if the "Emscripten platform" could get the same type of cross-compilation support as the desktop platforms eventually, but apart from bundling the Emscripten headers, this would also require to implement some of the "Emscripten magic" in the Zig linker.
Maybe projects like WaJIC [3] can help with this (this basically implements the "Emscripten magic" of embedding Javascript snippets in C/C++ source code, but without Emscripten (only the wasm-opt tool is needed AFAIK).
Anyway... it's a lot of fun to tinker around with this stuff in Zig :)
