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.

I'm open-sourcing my game engine
They use (uWebSockets)[https://github.com/uNetworking/uWebSockets], which was written in C++, but has an interface to use in NodeJS. It's been really performant for me in my simple tests compared to other popular websocket libs that slow down fairly quickly.

8 Best WebSocket Libraries For Node
µWebSockets, pronounced as "microWebSocket”, is a WebSocket library written in C++ and has Node.js bindings. Its design focuses on being efficient and scalable, making it ideal for applications that require high concurrency and low latency.

Recommendations for a CPP HTTP server which supports changing max threads at run time.
You can do that with any single threaded library that leaves threading to you. Like for example https://github.com/uNetworking/uWebSockets

What's the hot tech stack these days?
Websockets are also pretty valuable for updating the page in real time, there are servers in many languages. I'm a big fan of https://github.com/uNetworking/uWebSockets which is C++ but also has JS bindings to use with Node.js.

I have done a full benchmark of a POST REST API on my computer: Node.js vs Fastify vs Express.js vs Deno vs Bun vs GO. Node.js is used WITH and WITHOUT clustering on 6-core I7 processor
Can you include uWebsockets? https://github.com/uNetworking/uWebSockets

Nuklear – A single-header ANSI C immediate mode cross-platform GUI library
Not exaclty -- it looks like it's pretty overkill for my needs
I'm looking for something more like websocketpp[0], or even just grpc without a requisite proxy. uWebsockets looks really promising, being header only, but in the fine print requires a runtime library. unfortunately, none of that ecosystem seems to use cmake, making integrating it that much more of a pain.
why use cpp for this, I'm sure some HNer will ask. the ray tracer itself is using cuda, that's why. I've also debated
- running it as a grpc server and having some proxy in a more web-accessible language
- creating python bindings and using python to make a websocket/http server for it
neither of those are out of the question, but they're not my first choices, because I'd like to keep the build & execution simple. introducing dependencies, especially other executables, is in conflict with that.
i don't need anything particularly scalable -- a threaded implementation, or one using select() would be fine, if not preferable.

WebSocket Server in C
Really cool i also made and CAPI for using WebSocket in C, https://github.com/uNetworking/uWebSockets/tree/master/capi
I will take a deep look on your project thanks for sharing!

Socketify.py - Maybe the fastest web framework for Python and PyPy
We discover a really fast, small, and well maintained C++ Library called uNetworking/uWebSockets, but no C API available, so we create and adapt the full C API from uNetworking/uWebSockets and will integrate libuv powered fetch and file IO, this same C API is used by Bun
- In the 1970s, programming was an elite's task. Today programming is done by uneducated "farmers" and as a result, the care for smart algorithms, memory usage, CPU-time usage and the like has dwindled in comparison.

Enriching Payloads with MQTT 5 Metadata, using AWS IoT Core Rules Engine
First, we build two client simulators, for the car and the application client. We use MQTTJS for Javascript and its MQTT v5 implementation support. Step 1 below will describe the details of the MQTT client implementation.

MQTT in Plugin disconnects frequently
This all points to the direction that the underlying JS-Engine in the Streamdeck software might throttle the outgoing connections. I still don't understand what's under the hood. The user agent returns "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) QtWebEngine/6.3.1 Chrome/94.0.4606.126 Safari/537.36" What's the JS Engine in the Software? Is it Chrome? As far as I know, there are some issues with Websocket disconnects in Chrome due to aggressive throttling of background tabs. Could that be the cause here, too? https://github.com/mqttjs/MQTT.js/issues/1268

Connect to MQTT Broker with Websocket
MQTT.js is a fully open-source client-side library for the MQTT protocol, written in JavaScript and available for Node.js and browsers. On the Node.js side, it can be installed via global installation and connected via the command line. Also, it supports MQTT/TCP, MQTT/TLS, MQTT/WebSocket connections. It is worth mentioning that MQTT.js also has good support for WeChat Mini Program.
- Any library for mqtt that works ?
