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.

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

Has Boost lost its charm?
They might have good luck with https://github.com/beached/daw_json_link it has support for stuff like JSON lines and alike plus other ways that only use as much ram as their underlying data structures do as it parses directly to the user DS. Plus it has an iterator/range interface for things like arrays if needed.

New, fastest JSON library for C++20
We will add more benchmarks in the future, but for now you can see the comparison of daw_json_link with rapidjson. glaze is faster than daw_json_link, which is over twice as fast as rapidjson.
-
What are some cool modern libraries you enjoy using?
I am biased, but prefer https://github.com/beached/daw_json_link Super fast and you work with your native data structures without the overhead of DOM parsing/lookup

How to deserialise json into a C++ struct?
You can also look into https://github.com/beached/daw_json_link which claims to support nullable values in the readme.

JSON for Modern C++ 3.11.0
The library I author does this. https://github.com/beached/daw_json_link . It's fast, GB/s too, and provides the mapping mechanism, iteration types, json lines support, event based parser, along with a non-owning json_value for when the mappings don't fit right or if one is querying. Pretty much everything but an owning JSON value as it's not something I've ever needed more than temporarily and brings a lot of complexity that is solved by using the actual C++ data structures one is eventually parsing into anyways.
-
DAW JSON Link v3, a JSON serialization/deserialization library, is released
So DAW JSON Link does have a DOM view, however it does not have a owning view. The json_value(even supports JSON Path in a limited form) type and json_raw mappings can help here. But there is no hard line between parsing view the json_value and the mappings to concrete data structures. One can mix and match.
