Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

JSON for Modern C++ 3.11.0
My recent working on libraries are focusing on solving the problems you have. metapp is a runtime reflection library, jsonpp is a simple JSON library basing on metapp. More important, the meta data built in metapp is reusable for different purpose, such as serialization, scripting, etc.

jsonpp -- easy to use and reusable C++ JSON library
Reusable technology. The core technology is from C++ reflection library metapp developed by the same developer (wqking) of jsonpp. The technology is not unique to jsonpp, it's reusable for other purposes such as runtime reflection system, serialization, script binding, etc.

metapp - C++ open source library for runtime reflection and variant
You may read Core concepts and mechanism for some basic concepts. If you wonder how it parses the mystery type char const *(*(* volatile * (&)[][8])())[], or even 10 times more complicated type, it's not magic, it uses recursive template specialization.

Learn Modern C++
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 ;)

What C++ library do you wish existed but hasn’t been created yet?
https://github.com/nlohmann/json works well for me

It is either a clever technique or a sad failure
Here is one popular C++ library (nlohmann/json) removing its use.

How to compile project to separate files to prevent having single large executable as a result?
Before going into binary serialization I suggest you to get comfortable with serialization to text. You can try to write your data to text files and read them in again. Then after you get an idea of how this works you can try to use a library that writes to XML or json, e.g. nlohmann json
- What are some ways I can serialize objects?

C++ that allows tracking peer to peer multimedia streaming connections using a Flat File - NOT MySql
Download the single header file json.hpp from https://github.com/nlohmann/json/releases and place it in your project directory or an include directory.
