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.

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.

C++ Reflection for Component Serialization and Inspection
Exemple of a JSON library: https://github.com/nlohmann/json (For XML, there's tinyxml)

Has anyone embedded a web-UI into a C++ project?
Here's what I did: - I bought a theme that I liked, and used mstch as template engine (matched the theme's template format) - Imported rapidjson for parsing JSON, and used mstch for generating JSON (the JSON I generate is simple enough that I can do this) - Wrote an HTTP handler class for each page that handles the GET and POST requests, generating HTML or JSON depending on the request
-
Is there a good cross-platform (Windows / Linux) C or C++ library for file I/O?
And documentation in most cases is more user-friendly if you will use something like MkDocs(based on Markdown), example http://rapidjson.org/
- What is the best way to store multiple objects of a class as data in C++?
-
How to deserialise json into a C++ struct?
Use RapidJSON https://rapidjson.org/

DAW JSON Link v3, a JSON serialization/deserialization library, is released
It seems not super widely used compared to other famous libraries like RapidJSON, nlohmann-json, or simdjson. But it seems the author is very active in developing this project which can mitigate this "lack of community" issue.

Is cpp a good language for reading and writing large quantities of JSON files as quickly as possible?
have a look at rapidjson for a a nice simple json framework https://rapidjson.org/ I use it and it's quite fast and as good as anything I used in python.
-
What JSON library do you suggest?
So I just cloned https://github.com/Tencent/rapidjson to see what is the current status. At compile time they check if the C++ compiler supports the "noexcept" keyword, and if so they define RAPIDJSON_NOEXCEPT to be "noexcept". Throughout the implementation, RAPIDJSON_NOEXCEPT is added to quite a few function declarations (about a hundred of them).
- Storing data to be used in simulations.

How and where I can learn about Web sockets, APIs, Wrappers to connect with my C++ code?
RapidJSON is also excellent, like fantastic when performance matters. Not sure there's a much faster JSON implementation anywhere, and I've written my own SAX-style parser as a fun, hobby project for C++.
- Can anyone point me to an open-source project that correctly uses allocators?
What are some alternatives?
JsonCpp - A C++ library for interacting with JSON.
ArduinoJson - 📟 JSON library for Arduino and embedded C++. Simple and efficient.
simdjson - Parsing gigabytes of JSON per second : used by Facebook/Meta Velox, the Node.js runtime, ClickHouse, WatermelonDB, Apache Doris, Milvus, StarRocks
Boost.PropertyTree - Boost.org property_tree module
cJSON - Ultralightweight JSON parser in ANSI C
yaml-cpp - A YAML parser and emitter in C++
Jansson - C library for encoding, decoding and manipulating JSON data
