    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 ;)

    Looks like this makes a json string with https://github.com/nlohmann/json then uses libcurl to send it to a URL using an API key that has to be in an environment variable.

    I would add an honorable mention for Niels Lohmann's Json library. It is less performant than RapidJSON, but it easier to use and integrate imo. If JSON based IO isn't a hot path in your game, this lib will likely be easier to use.
