RESTinio VS µWebSockets

In my past job, we used https://github.com/Stiffstream/restinio and absolutely loved it. It's not as active but it honestly didn't need much.

Here's a C++ REST framework for you to use too: https://github.com/Stiffstream/restinio

I had a good experience using restinio for a small ASIO HTTP server recently.

It uses restinio https://github.com/Stiffstream/restinio with great success ;)

For networking, pick a networking library. Restinio is a fair choice for HTTP. But, again, feel free to pick others.

You may find this worthwhile: https://github.com/Stiffstream/restinio/issues/101 FWIW, I used Restbed successfully for 3.5 years before switching personal projects to Restino. I've left the job that used Restbed, but I think they are still using it.

Contrary to the direction most people go, I've been writing REST APIs as C++ servers using two different fairly full featured C++ REST frameworks: first using https://github.com/Corvusoft/restbed and more lately using https://github.com/Stiffstream/restinio. These can be peers with any other server, while living on embedded and/or high compute devices for video encode/decode/analysis, deployed ML models, encryption for and remote process communications, model data collection and similar expensive or in-field processing. In both high compute and in-field-no-internet situations creating REST APIs in C++ enables speed and system controls not present in the majority of the mainstream REST frameworks. It's a big world, and here comes ubiquitous high compute...

If you need an embedded C++ HTTP server then there are plenty of libraries/frameworks (in random order): Crow, RESTinio, Boost.Beast, cpp-httplib, http_backend, Pistache, RestBed, served, proxygen, Simple-Web-Server, drogon, oat++.

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
