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.

New, fastest JSON library for C++20
Shouldn't your benchmark use a somewhat larger JSON? Something from https://github.com/boostorg/json/tree/develop/bench/data, for instance.

JSON for Modern C++ version 3.10.0
You should be able to build and include boost json as a standalone subproject in CMake if you are using C++17. (Or also possible to use as header only lib)
It gets far more complicated with C++11, since you also need a ton of other boost modules there.
For more Details you can read the Readme of it. https://github.com/boostorg/json

Visual Studio's Natvis Debugging Framework Tutorial
I'm gonna throw this out there - Boost.JSON comes with .natvis visualizers for all of its data structures, so you can inspect all of its types in the debugger and get nice insights: https://github.com/boostorg/json/blob/932b97e5ce899f3faebb7b7ab5a68b023131b77f/include/boost/json/json.natvis
