This project (Github branch main) I built this app entirely in CPP and I used the CrowCpp framework to run it.
Experience using crow as web server
11 projects | /r/cpp | 6 Nov 2023

I'm investigating using C++ to build a REST server, and would love to know of people's experiences with Crow-- or whether they would recommend something else as a "medium-level" abstraction C++ web server. As background, I started off experimenting with Python/FastAPI, which is great, but there is too much friction to translate from pybind11-exported C++ objects to the format that FastAPI expects, and, of course, there are inherent performance limitations using Python, which could impact scaling up if the project were to be successful.

Transport agnostic Websocket library

I recommend Crow, it's a web framework that supports HTTP and Websockets. It's a bit larger than being only there to just let you compose or decode a packet. But I'm pretty sure everything you mentioned is there already :)

It's also very useful to get to grips with using some popular libraries. Some might be ones that you'll find yourself using everywhere (e.g. fmt, spdlog, catch2), and some that have more specific usage, but are good to try out and explore what C++ can do in a ridiculously easy-to-use manner (e.g. crow, Dear ImGui). Make some toy projects that use some of these and you'll learn a lot.
Can I use C++ in the backend ?? Any frameworks there ??

I've been working on Crow for quite a while now, it's a pretty cool framework IMO.

Have there been any attempts to build a REST API service on top of either Boost.asio or Boost.beast?
