A quick guide to running wasm files outside the browser

General info

The following code should work to test WebAssembly in various JS runtimes with minor modifications:

const bytes = /* read a .wasm file somehow */;
const mod = new WebAssembly.Module(bytes);
const instance = new WebAssembly.Instance(mod, { /* imports */ });

const { foo, bar } = instance.exports;

These instructions are based on this blogpost by Anton Semjonov and this video by Animortis Productions. Please follow the link if you want more details, they go into much more detail about each step, whereas this document is more focused on being a concise cheat sheet. Let's go.

Install base system

Boot the Ubuntu installation medium. When asked, choose the "Try Ubuntu" option and open a terminal.

Switch to root, otherwise you'll have to type sudo all the time:

sudo su -
