Just playing around with WebAssembly and stuff

Getting Started

At the moment this repo just contains a FizzBuzz C program, hello.c, with a minimal setup for running this from JavaScript via WASM.

  1. Install Emscripten. Instructions at https://emscripten.org/docs/getting_started/downloads.html
  2. Run npm start - this runs npm run build and then node hello.build.js

package.json's build command runs emcc hello.c -s WASM=1 -o hello.build.js to compile hello.c to hello.build.wasm and create hello.build.js, which wraps the WebAssembly.

This hello.build.js file can also be used in a browser environment; change the build command to output html (e.g. emcc hello.c -s WASM=1 -o hello.html) and serve this file to try it out.
