Usage
import Context from "https://deno.land/std@$STD_VERSION/wasi/snapshot_preview1.ts";
const context = new Context({
args: Deno.args,
env: Deno.env.toObject(),
});
const binary = await Deno.readFile("path/to/your/module.wasm");
const module = await WebAssembly.compile(binary);
const instance = await WebAssembly.instantiate(module, {
"wasi_snapshot_preview1": context.exports,
});
context.start(instance);
