htcpp VS µWebSockets

I'm always a bit bothered by them saying they are the "only" web server that can do this. First you can also just configure it in a way where it will not use HTTPS (e.g. if you provide an IP:port instead of a hostname). And if you do require specific configuration to enable HTTPS and automatically get certificates via ACME, then lots of other web servers can do this too. Even my own web server can do it: https://github.com/pfirsich/htcpp (see https://github.com/pfirsich/htcpp/blob/main/configs/acme.jom... for an admittedly much more complicated config).

Cool stuff! I am currently converting my io_uring based HTTP server (https://github.com/pfirsich/htcpp) to using coroutines as well, so this is cool to see. (WIP library here: https://github.com/pfirsich/aiopp)

I recently built an HTTP(S) server myself (https://github.com/pfirsich/htcpp) and did not find something like you are looking for. If you also don't find anything (but please link it if you do!), consider just running your server on a publicly accessible VM and listening on port 80 and you will be bombarded by various people trying to break in. Most of it will be useless, like checks for unprotected phpMyAdmin and stuff like that, but I did find a few bugs that way. I even found some TLS issues (of course listen on 443 instead).

I am serving static HTML from a web server, which I have built myself using C++: https://github.com/pfirsich/htcpp. I am not sure if that even counts, but I'm kind of proud of it. And I use it to serve my personal website: https://theshoemaker.de.

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
