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.

Node on Web. Use Nodejs freely in your browser with Linux infrastructure.
"Wasm Workers Server (wws) is an open source tool to develop and run serverless applications server on top of WebAssembly. The applications are composed by multiple modules called workers. Each of these tiny modules is in charge of replying to a specific HTTP endpoint in your application." Wasm Workers Server, "JavaScript Workers based on JavaScript work out of the box with Wasm Workers Server. The server integrates a JavaScript interpreter compiled into a WebAssembly module. Currently, the interpreter we support is quickjs and we are working on adding new ones." JavaScript

Client side Rest server?
Using an extension we can create an offscreen document, connect to a Native Messaging host, stream stdin to a local application, and stream stdout to the browser (Web page), see offscreen-webrtc.

Is websockets is good for sending files?
There are multiple ways to upload and send files, including WebRTC datachannels, e.g., https://github.com/guest271314/offscreen-webrtc, WebTransport, WebTorrent https://github.com/jeremyckahn/secure-file-transfer, WebSocket, WebSocketStream, or just using Fetch and Streams. fetch() on Chromium-based browsers also supports duplex:'half' in request init for bi-directional streaming capability.

How to serve exactly 1 HTML file and 1 JavaScript file, then exit the program?
To achieve this specific task, once an HTML page is loaded into the browser, and a ServiceWorker is registered for that scope, the server does not need to remain active to maintain the functionality of intercepting requests from the Web page (popup window) to the ServiceWorker, where the ServiceWorker can itself make requests to, for example, the same local server to execute parec and pipe output to multiple EventSource responses within the same initial connection, or pipe data to a single ReadableStream served with Response() and event.respondWith(), e.g., see https://github.com/guest271314/offscreen-webrtc, https://github.com/guest271314/sw-transfer-stream.

[AskJS] Has anybody implemented and compiled ServiceWorker specification to a standalone executable?
I've already built it https://github.com/guest271314/captureSystemAudio#web-accessible-resources-transferable-streams-media-capture-transform-breakout-box, https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/capture_system_audio.js; see also https://github.com/guest271314/sw-transfer-stream and https://github.com/guest271314/offscreen-webrtc. I'm just trying to reduce steps https://github.com/guest271314/requestClient.

Run untrusted code in a Web Worker
Yes, you can create an iframe and/or a new window that you have complete control of to execute arbitrary code using either localhost or an extension; e.g., https://github.com/guest271314/sw-transfer-stream, https://github.com/guest271314/offscreen-webrtc.
-
Is there any way to write code on one screen and see output on another?
Yes. You can use WebRTC. See https://gist.github.com/guest271314/53e00c6765aa256362fb52c08e82d189, https://github.com/guest271314/offscreen-webrtc.

What chrome extensions are you using in 2023?
Establish WebRTC connection between offscreen document and arbitrary Web page to transfer data from ServiceWorker to Web page https://github.com/guest271314/offscreen-webrtc

[AskJS] What are the worst case scenarios for programmatically setting arbitrary Web pages (Origins) as Client or WindowClient of a ServiceWorker?
There are workarounds which involve using an iframe https://github.com/guest271314/persistent-serviceworker/tree/main/chromium_extension_web_accessible_resources_iframe_message_event or window.open() https://github.com/guest271314/sw-transfer-stream or and offscreen document https://github.com/guest271314/offscreen-webrtc with WebRTC - however that involves loading an entire HTML document, and each has its own deficienfies - with all of the Window features that we do not really need just to transfer data between the Web page I have control of and the ServiceWorker I have control of.
