Top 7 C++ json-serialization Projects

json

93 40,148 7.6 C++

JSON for Modern C++

Project mention: Learn Modern C++ | news.ycombinator.com | 2023-12-26

I have not done a "desktop" program in 25+ years and never using C++ (or C), since then I'm mostly a web developer (PHP,Elixir, JS, Kotlin etc).
I'm currently doing a C++ audio plugin with the Juce framework.
This website has been a good resource, alongside https://www.learncpp.com
But I was actually close to give up before using those two things:
- https://github.com/nlohmann/json : my plugin use a json api backend and the Juce json implementation is atrocious (apparently because of being born in previous c++ version), but this library is GREAT.
- ChatGPT 4. I'm not sure I would have "succeeded" without it, at least not in a reasonable time frame. ChatGPT 3.5 is slow and does not give good results for my use case but 4 is impressive. And I use in a very dumb way, just posing question in the web UI. I probably could have it directly in MSVC?
Also I must say, for all its flaws, I have a renewed appreciation for doing UI on the web ;)

On the other hand, I'd like to bring in the json library of my choice, e.g. https://github.com/nlohmann/json or https://github.com/danielaparker/jsoncons. So I'd prefer the web server library provides as little as possible in the way of Json support, and certainly doesn't get in the way of using my library of choice. Similarly, I'd like to use my choice of automatic object serialization.

restc-cpp

5 583 6.3 C++

Modern C++ REST Client library

Project mention: What is the industry standard today in C++ to deploy REST microservices in Kubernetes? | /r/cpp | 2023-09-06

My favourite was Microsoft's cpprestsdk, but for some reason now is in maintenance mode, I don't know why, so it's hard to suggest it for new projects. A nice alternative is restc-cpp, that's has a good high-level interface, if this is what you want.

python-rapidjson

Python wrapper around rapidjson
json-voorhees

You're free to extend it yourself or use an existing extension if it's such a sticking point lol. Hell, the one I linked has strongly typed datetimes.
