Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

A better way to set up a Cloudflare worker project locally with Miniflare
Recently Cloudflare introduces Miniflare. As its name suggests, Miniflare is a feature-rich but miniature version of Cloudflare worker. Miniflare is a simulator that provides an environment for developing and testing Cloudflare worker scripts locally. Miniflare is written in typescript and supports most of the Cloudflare worker features like the KV database, durable objects, WebSockets, etc.

[AskJS] Is there an JavaScript engine agnostic server module that can be imported into Bun, QuickJS, Deno, and Node.js?
Another implementation of the above is Cloudfare workers you might be capable of grasp some ideas from here https://miniflare.dev

Workerd: The Open Source Cloudflare Workers Runtime
Is there an ETA on Miniflare v3? Ran into a problem recently using overlapping keys with forward slashes as they were not sanitized properly: https://github.com/cloudflare/miniflare/issues/167

Part 2: KV store
The KV API is only available on Cloudflare Workers. But, during development, Rakkas runs our app on Node.js. Fortunately, the Miniflare project has a KV implementation for Node. The other two packages that we've installed (@miniflare/kv and @miniflare/storage-memory) are what we need to be able to use the KV API during development. Let's create a src/kv-mock.ts file and create a local KV store to store our ublog posts ("twits") while testing:

Web Workers are the Future! 🏗
I used hono (a wrapper around miniflare) to handle some of the boilerplate around request and routing logic. It's also refreshingly fast! 🔥
-
Deploy a GitHub Application to Cloudflare Workers
The simple explanation is that I'm proposing use of the Service Worker API. Cloudflare offers a flat, free, 100k requests a day if you can keep it cutting edge, has local development and testing options with miniflare and a key/value (KV) store.

Serverless Remix Sessions with Cloudflare Pages
When we run the dev script, this will ensure that the local runtime environment Miniflare will bind a KV with the name sessionStorage to our Pages function.

Show HN: Slshx – React-Inspired Discord Commands on Cloudflare Workers
Slshx is a library for building strongly-typed Discord commands (https://discord.com/developers/docs/interactions/application...) that run on Cloudflare Workers (https://workers.cloudflare.com/), using a React-inspired syntax (hooks and JSX). It supports all Discord command types/options, autocomplete and interactive message components. During development, it automatically deploys your commands whenever you change your code.
I created this because I think Cloudflare Workers are a great fit for hosting Discord commands, but there wasn't an easy way to get started that had a fun development experience. I also wanted to see what a Miniflare-first (https://github.com/cloudflare/miniflare) library could look like.

JavaScript Standard Input/Output: Unspecified
Synchronous. Though non-blocking when we read the message from the browser, execute the command, then stream data output from the local application to the browser piped from QuickJS std.popen(), capture_system_audio.js

IAMA senior javascript dev, ask me anything
I've already achieved the requirement multiple ways, already; from using Native Messaging https://github.com/guest271314/native-messaging-espeak-ng, to using GNU Core Utilities tail, to Deno.watchFs() https://github.com/guest271314/fs, et al., see captureSystemAudio. The one approach I have not yet achieved is compiling to Emscripten - with SSML support.

Need help with ytdl-core and ExpressJS
Sure, see https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/background.js, in pertinent part

Kindly review this C QuickJS HTTP streaming Web server module
This is my second time writing C source code capture_system_audio.c. I got a lot of help doing that, too . I basically implemented the same Native Messaging host algorithm in C, C++, Python, WASI/WebAssembly, and JavaScript (Node.js, QuickJS) which is the programming language I write code most using.

Termino.js: Create command based apps on any website - great for games, chat-bots, animations and real world apps!
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.

How to serve exactly 1 HTML file and 1 JavaScript file, then exit the program?
Technically I can just serve the raw data as long as the server is capable of opening creating sub-processes, e.g., using EventSource https://plnkr.co/edit/qX5tepJ38BuDOSZj?preview, in which case I would just need to convert this https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/capture_system_audio.c to accept GET request, read the URL, and send the named event stream to the client.

[AskJS] Has anybody implemented and compiled ServiceWorker specification to a standalone executable?
Chromium and Chrome refuses to capture monitor devices on Linux. Read this https://github.com/edisionnano/Screenshare-with-audio-on-Discord-with-Linux README and the README at https://github.com/guest271314/captureSystemAudio very carefully. At best you can capture tab audio, not whatever is output to speakears and headphones, in spite of the systemAudio constraints, which is poorly named, and actually misleading.

You can learn React and Python in browser without dev environment.
An example of using Native Messaging to capture "What-U-Hear", sound output to speakers and headphone, launching native GUI's https://github.com/guest271314/captureSystemAudio/tree/master/native_messaging/capture_system_audio; an adapter for espeak-ng so we can capture the output of speech synthesis engine and stream output to the browser https://github.com/guest271314/native-messaging-espeak-ng.
