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.

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.

Parsing JSON faster with Intel AVX-512
Is this the repo? Never saw it linked in our convo, and I’d like to give it a whirl.

Is there something like GSON available in C++?
daw_json_link is what you're looking for : https://github.com/beached/daw_json_link

Deserializing JSON Fast
Check out https://github.com/beached/daw_json_link , it provides a non-typeerased way to parse JSON straight into user-defined data structures.

Experience using crow as web server
I'm investigating using C++ to build a REST server, and would love to know of people's experiences with Crow-- or whether they would recommend something else as a "medium-level" abstraction C++ web server. As background, I started off experimenting with Python/FastAPI, which is great, but there is too much friction to translate from pybind11-exported C++ objects to the format that FastAPI expects, and, of course, there are inherent performance limitations using Python, which could impact scaling up if the project were to be successful.

REST APIs using C++. (Is this even done much?)
How about Crow?

What library/framework to use for writing a Web server?
https://github.com/CrowCpp/Crow is super easy to use
-
Transport agnostic Websocket library
I recommend Crow, it's a web framework that supports HTTP and Websockets. It's a bit larger than being only there to just let you compose or decode a packet. But I'm pretty sure everything you mentioned is there already :)
-
What's next after learncpp.com?
It's also very useful to get to grips with using some popular libraries. Some might be ones that you'll find yourself using everywhere (e.g. fmt, spdlog, catch2), and some that have more specific usage, but are good to try out and explore what C++ can do in a ridiculously easy-to-use manner (e.g. crow, Dear ImGui). Make some toy projects that use some of these and you'll learn a lot.

Can I use C++ in the backend ?? Any frameworks there ??
I've been working on Crow for quite a while now, it's a pretty cool framework IMO.
