The reason for using

await readable.pipeTo(writable)

is the .crswap file is automatically removed when the Promise fulfills.

Here's one way to write arbitrary volumes of data to the same file, without generating a bunch of orphan .crswap files.

The gist is

Executing AssemblyScript directly, and compiling to JavaScript with tsc, Deno, and Bun (and executing WASM directly with bun)

Installing

bun install typescript@next assemblyscript @types/node
bun add v1.2.1-canary.15 (5633ec43)

installed [email protected] with binaries:
 - tsc

In Chromium or Chrome browsers navigate to chrome://settings/searchEngines. The page looks something like this. Here I'm showing what Chromium Version 134.0.6949.0 (Developer Build) (64-bit). On Linux.

Notice that ".(Default)".

Facebook's Static Hermes doesn't provide a way to read stdin by default. Does hermes expose the capability to read standard input and write standard output? #1469.

CommonJS support was removed. ECMAScript Modules are not yet supported. We can't use imported files to facilitate reading from standard input. There's no process.argv to read arguments passed to the program.

There's static_h/examples/ffi/fopen.js which opens and reads a flat file.

Modifying that code to read from /dev/stdin on Linux

"Highly skilled" programmers for "high-tech" or capitalism working as expected?

I'm currently domiciled in the U.S. I don't watch or listen to "the news". I don't support Democrats or Republicans.

The other day somebody told me there's an H-1B visa schism within the Republican Party.

I said, alright, show me what "the left" says, and show me

Compiling JavaScript to WASM with WASI support using Static Hermes

WASI High Level Goals

(In the spirit of WebAssembly's High-Level Goals.)

Took me a while to figure this out. Posted here to share just in case anybody else in the world is trying to install Rust on an external USB device, for example, to get around build with Rust resulting in running out of disk space on a live Linux USB running on a temporary file system. See Is there a way to [disable] caching crates?.

I have been trying to build Roll your own JavaScript runtime for a while now. My previous attempts resulted in an error due to the disk space being filled by cargo writing downloaded crates to $HOME/.cargo. I start out with around only 1 GB on the live Linux USB temporary file system. I have access to a few external USB devices ranging between 64 GB and 128 GB capacity, so that's not the issue.

This is what worked for me. Making use of CARGO_HOME and RUST_HOME environment variables, along with naming the directories accordingly

	import { createSecureServer } from "node:http2";
	import { readFileSync } from "node:fs";
	import { Readable, Writable } from "node:stream";

	const responseInit = {

	headers: {
	"Cache-Control": "no-cache",
	"Content-Type": "text/plain; charset=UTF-8",
	"Cross-Origin-Opener-Policy": "unsafe-none",

	Deno.bench("Deno, Bun, Node.js TypeScript Benchmarks", async (b) => {
	// Open a file that we will act upon.
	// using file = await Deno.open("a_big_data_file.txt");

	// Tell the benchmarking tool that this is the only section you want
	// to measure.
	b.start();

	// Now let's measure how long it takes to read all of the data from the file.
	// await new Response(file.readable).arrayBuffer();
