jerryscript VS txiki.js

JerryScript

Some IoT platforms use Duktape and JerryScript as their engines.

I've been having a lot of fun with https://kalumajs.org/ recently for silly JS embedded things. It's been great so far, and has a cool little community!

It's a runtime built on top of JerryScript, which has been pretty neat to look into as well: https://jerryscript.net/

Jerryscript came to mind : https://github.com/jerryscript-project/jerryscript

I personally quite like JerryScript

Based on JerryScript, the creators also provide an IDE and serial communication tool on their website. There's also ample documentation and guides. Looking forward to getting more into this.

I hear you loud and clear.

There are subsets of JS for embedded device e.g. Espruino https://github.com/espruino/Espruino for BangleJS https://shop.espruino.com/banglejs also with 4MB or JerryScript https://jerryscript.net

Fitbit uses Jerryscript in some of their watch OSes. Well, at least they were last time I was tinkering with making my own watch face

txiki.js

// https://github.com/denoland/deno/discussions/17236#discussioncomment-4566134 // https://github.com/saghul/txiki.js/blob/master/src/js/core/tjs/eval-stdin.js async function readFullAsync(length, buffer = new Uint8Array(65536)) { const data = []; while (data.length < length) { const input = await open("/dev/stdin"); let { bytesRead } = await input.read({ buffer }); await input.close(); if (bytesRead === 0) { break; } data.push(...buffer.subarray(0, bytesRead)); } return new Uint8Array(data); }

I've only dabbled with the shared libraries once, with the help of the owner of the lnked repository. I wound up solving the issue adjusting the code I was working on https://github.com/saghul/txiki.js/issues/294.

I have written the same code in C++ https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/capture_system_audio.cpp, Python https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/capture_system_audio.py, and QuickJS (C source code) https://github.com/saghul/txiki.js/issues/294. QuickJS is the only implementation that winds up clipping the end of real-time audio capture.

QuickJS is awesome, simple to use and very easy to integrate.

Over the past few years I slowly built a small JS runtime using QuickJS as the engine and libuv as the platform layer, amongst other things, in case anyone wants to take a look: https://github.com/saghul/txiki.js
