• V8

V8 is Google’s open source high-performance JavaScript and WebAssembly engine, written in C++. It is used in Chrome and in Node.js, among others. It implements ECMAScript and WebAssembly, and runs on Windows 7 or later, macOS 10.12+, and Linux systems that use x64, IA-32, ARM, or MIPS processors. V8 can run standalone, or can be embedded into any C++ application.

• SpiderMonkey

SpiderMonkey is Mozilla’s JavaScript and WebAssembly Engine, used in Firefox, Servo and various other projects. It is written in C++, Rust and JavaScript. You can embed it into C++ and Rust projects, and it can be run as a stand-alone shell. It can also be [compiled](https://bytecodealliance.org/articles/making-javascript-run-fast-on

Why I use node, deno, bun, qjs, tjs at the same time.

Winds up being a (not the) rather comprehensive JavaScript toolbox. The idea being for the modern JavaScript programmer can use all of the tools available for a given requirement, task or job, without preference for any. No external bundlers or compilers are needed. No frameworks are needed. I can use qjs or tjs for systems with minimal RAM and disk space; and when I want to use Web API's deno makes an effort to provide those interfaces. In some cases I can run the exact same code in bun, deno, and node, which provides a means to perform 1:1 testing as to performance.

There's probably a few things I am unintentionally omitting below. These are just a brief synposis. I'll update accordingly.

Today we will be using the Web browser (Google Chrome for Testing 125) as a local HTTP over TCP socket server.

WICG Direct Sockets specifies an API that provides TCPSocket, UDPSocket, and TCPServerSocket.

In Chromium based browsers, for example Chrome, this capability is exposed in an Isolated Web Apps (IWA).

Previously we have created an IWA that we launch from arbitrary Web sites with open(),

Compiling a standalone executable using modern JavaScript/TypeScript runtimes

We have the same code working using node, deno, and bun.

E.g.,

bun run index.js

// vendor/esm.sh/v135/signal-polyfill@0.1.0/denonext/signal-polyfill.mjs
var $ = function(e, o) {
  return Object.is(e, o);
};
var N = function(e) {
  let o = i;
  return i = e, o;
};
var ce = function() {
  return i;

So we need people to have weird new
ideas ... we need more ideas to break it
and make it better ...

Use it. Break it. File bugs. Request features.

An issue filed in Bun I find interesting, Bun runtime plugin onResolve doesn't filter non-file: protocol imports #9863.

The gist is handling Ecmascript static import and dynamic import() that are arbitrary specifiers and setting arbitrary content. Something like

import demo1 from '1.demo';

console.log('demo 1', demo1);

import demo2 from 'demo:2';
