µWebSockets VS lvgl

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.

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.

You can do that with any single threaded library that leaves threading to you. Like for example https://github.com/uNetworking/uWebSockets

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.

Can you include uWebsockets? https://github.com/uNetworking/uWebSockets

μWebSockets Génial, rapide, peut transformer l’eau en vin. Nécessite C++17.

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.

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!

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

So here is the thing: The iPod Nano 7g is from 2012. I've seen many people designing custom PCBs and releasing Kickstarter projects for custom audio players[5] or game handhelds[6]. I know Rockbox (which is great, but its lacks support for Wifi and Bluetooth AFAIK and just does not compete with the UX of iPod's audio book features in my opinion) and iPod Linux. 10 years ago someone even reverse engineered the iPod Nano 6g display[3].

Although I'm not skilled enough in PCB-Design, after some research I found the Lilygo T-Display S3 Pro[4] based on ESP32 S3, which would be the size, but lacks audio and OS. There is also the Mango PI CyberPad[7], which looked interesting, but maybe is already too clunky.

Programming wise, LVGL[8] may be a good framework to develop a modern and efficient UI - at least it looks promising.

So, why is nobody interested in recreating an iPod nano like device? It should be doable with modern tech, but Phones have completely taken over the marked...

LVGL is a graphics library used mostly for embedded UI's. Main website: https://lvgl.io/

Popular embedded UI library

If you need something written in C and very tiny, I recommend LVGL https://lvgl.io/

The factory code uses the Lvgl graphic library. https://github.com/lvgl/lvgl

I'm trying to interface SPI LCD (ILI943) with Zynq 7020 (PYNQ-Z2 board) and LVGL embedded UI libary. And considering between two approaches:
