zig-wasm-test

A minimal Web Assembly example built from Zig's init-lib.

Originally expanded on this great gist from @josephg but now superceded with better support in 0.4.0:

To build this project you need to follow the steps there to get a wasm enabled version of LLVM setup.

Building

To build this project with a working Zig at 0.4.0 and TypeScript install at the project root just type.

zig build install

You need to move the resulting wasmtest.wasm file from /bin/ 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

Running

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.
