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,
});
const {
_start: start,
_initialize: initialize,
memory,
} = instance.exports;
context.memory = memory as WebAssembly.Memory;
if (start instanceof Function) {
start();
} else if (initialize instanceof Function) {
initialize();
} else {
throw new Error(
"No '_start' or '_initialize' entry point found in WebAssembly module, make sure to compile with wasm32-wasi as the target.",
);
