## WebAssembly support
|
|
|
|
Deno can execute [WebAssembly](https://webassembly.org/) modules with the same
|
|
interfaces that
|
|
[browsers provide](https://developer.mozilla.org/en-US/docs/WebAssembly).
|
|
|
|
<!-- deno-fmt-ignore -->
|
|
|
|
```ts
|
|
const wasmCode = new Uint8Array([
|
|
0, 97, 115, 109, 1, 0, 0, 0, 1, 133, 128, 128, 128, 0, 1, 96, 0, 1, 127,
|
|
3, 130, 128, 128, 128, 0, 1, 0, 4, 132, 128, 128, 128, 0, 1, 112, 0, 0,
|
|
5, 131, 128, 128, 128, 0, 1, 0, 1, 6, 129, 128, 128, 128, 0, 0, 7, 145,
|
|
128, 128, 128, 0, 2, 6, 109, 101, 109, 111, 114, 121, 2, 0, 4, 109, 97,
|
|
105, 110, 0, 0, 10, 138, 128, 128, 128, 0, 1, 132, 128, 128, 128, 0, 0,
|
|
65, 42, 11
|
|
]);
|
|
const wasmModule = new WebAssembly.Module(wasmCode);
|
|
const wasmInstance = new WebAssembly.Instance(wasmModule);
|
|
const main = wasmInstance.exports.main as CallableFunction
|
|
console.log(main().toString());
|
|
```
|
|
|
|
And for files:
|
|
|
|
```ts
|
|
const wasmCode = await Deno.readFile("main.wasm");
|
|
const wasmModule = new WebAssembly.Module(wasmCode);
|
|
const wasmInstance = new WebAssembly.Instance(wasmModule);
|
|
const main = wasmInstance.exports.main as CallableFunction;
|
|
console.log(main().toString());
|
|
```
