A minimal Web Assembly example built from Zig's init-lib.
To build this project with a working Zig at 0.9.1 and TypeScript install at the project root just type.
zig build
You need to move the resulting wasmtest.wasm file from /zig-cache/ to /www/. One has been committed if you're happy omitting this step.
For good measure you can then build the TypeScript file:
cd www
tsc wasmtest.ts
Start the web server of your choice serving the www folder and navigate to wasmtest.html in your browser of choice. The value 7 should be output in the console.
