webassembly-stdweb

A library for binding standard javascript function to WebAssembly language such as AssemblyScript

Actual bindings

namespace	status
console	partially
websocket	partially
document	not started yet

How to make bindings

const fs = require('fs');
const loader = require('../src/loader');

let wasmModule = undefined; // IMPORTANT
const getModule = () => wasmModule; // IMPORTANT

let imports = {};
imports["_console"] = require('.../bindings/console')(getModule);
imports["_websocket"] = require('.../bindings/websocket')(getModule);

wasmModule = loader.instantiateBuffer(fs.readFileSync('./build/optimized.wasm'), imports);

// DO SOMETHING

How to use Declarations in AssemblyScript

Console

import {Console} from ".../declarations/console";

Console.log("Hello World !");
Console.log(42);
Console.log(0.0);

WebSocket

import {WebSocket} from ".../declarations/websocket";

let ws = new WebSocket("ws://localhost:8080");

export function onClose(): void {
    // DO SOMETHING
}

export function onError(): void {
    // DO SOMETHING
}

export function onMessage(message: string): void {
    // DO SOMETHING
}

export function onOpen(): void {
    // DO SOMETHING
}

ws.registerCallbackOnOpen(onOpen);
ws.registerCallbackOnClose(onClose);
ws.registerCallbackOnError(onError);
ws.registerCallbackOnMessage(onMessage);

ws.sendMessage("Hello World !")
