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.

A good C library to parse json data
I've used picojson. What makes it pretty awesome is it's completely contained into a single H file.
-
Is the madness ever going to end?
Especially if the library is even slower than smaller alternatives like [1].
But that's just my personal opinion, I understand that other people have different priorities and are fine with including 785kb of C++ template headers s long as public interface suits their needs and taste.
This is just an example for the kind of freedom software allows for, because it doesn't cost you anything and there is no objectively "better" in this case.

how to build a JSON parser?
I like pico json because it is a self-contained in a header file.

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?
json - JSON for Modern C++
JsonCpp - A C++ library for interacting with JSON.
json11
simdjson - Parsing gigabytes of JSON per second : used by Facebook/Meta Velox, the Node.js runtime, ClickHouse, WatermelonDB, Apache Doris, Milvus, StarRocks
ujson
cJSON - Ultralightweight JSON parser in ANSI C
ArduinoJson - 📟 JSON library for Arduino and embedded C++. Simple and efficient.
