native-messaging-nodejs VS jsvu

And/or control node and any other programming language from the browser using Native Messaging native-messaging-nodejs.

We can process asynchronous tasks without blocking reading stdin (e.g., full-duplex).

WHat do you mean by "contribute"? I download only the node executable using download-node-nightly-executable to run native-messaging-nodejs, servers, or whatever else I decide to experiement on - without downloading any packages.

I re-wrote the original code substituting using readSync for process.stdin.on('readable', () => {}) and including process.stdout._handle.setBlocking(true) and readFullSync function contributed by a Deno user https://github.com/guest271314/native-messaging-nodejs/blob/main/nm_nodejs.mjs. I wanted to a) get the input message (up to 1MB at a time) echo'ed back to the client; and b) get away from using process.stdin.on('readable', () => {}), rather use an approach that did not include event listeners; c) get away from using CommonJS and package.json and instead use Ecmascript modules without package.json.

If you want you can use a Node.js Native Messaging host https://github.com/guest271314/native-messaging-nodejs, Deno, QuickJS, txiki.js, Bun, C, C++, Python, WASI/WebAssembly or whatever language is built in, e.g., Bash.

I just fetch the nightly node executable, get rid of everything else in the archive, use .mjs extension for import to work without package.json, then I can connect to the host https://github.com/guest271314/native-messaging-nodejs, and start subprocesses, e.g., raw PCM streams, where stdout is streamed to the client (browser), e.g, https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/capture_system_audio_node.js.

Yes, utilizing Native Messaging https://github.com/guest271314/native-messaging-nodejs.

For debugging elements kinds to figure out a given object’s “elements kind”, get a debug build of v8 (either by building from source in debug mode or by grabbing a precompiled binary using jsvu), and run: out/x64.debug/d8 --allow-natives-syntax Note that “COW” stands for copy-on-write, which is yet another internal optimization. :))

See jsvu.

There is more than one JavaScript engine besides V8 https://github.com/GoogleChromeLabs/jsvu. Frameworks are not necessary at all to master JavaScript as a whole.

Node.js is not the only option for JavaScript engines. There are several, including Deno, QuickJS, et al. https://github.com/GoogleChromeLabs/jsvu.

To get a better understanding of why our clever one-liner FizzBuzz solution is slower, we need to take a look at how V8 works. V8 is the Javascript engine that powers NodeJS, you can directly download a binary version of the engine either via JSVU instead of compiling locally.

Tangentially related: jsvu seems to be the easiest way to install most JS engines on most platforms. This can be useful comparing performance or compatibility across JS runtimes without firing up emulators.
