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.
json_struct
- JSON for Modern C++ 3.11.0
-
Is there something like GSON available in C++?
I made a header only library with good performance and low memory overhead to parse JSON straight into structs, and serialize structs to JSON. How to parse into non map/object types is configurable with template functions. json_struct
- Hardcore metaprogramming in the wild
-
What JSON library do you suggest?
json_struct for serializing directly to and from structs. Its one header only and performs on par with RapidJSON.

A C++ compile-time static reflection ConfigLoader framework
Hi, I wrote JsonStruct. A header only library for parsing to and from structs. So I basically had the same problem: how to add metadata. I desided for having an additional macro. This leads to make it possible to add metadata to structs that you cannot modify for instance. Also, you can deside not to add metadata for all of the member of a struct. Please check it out! https://github.com/jorgen/json\_struct

C++ JSON libs Reviewed/Compared - nlohmann, rapidjson, boost.json
Nice page! I have written a JSON header only library that parses and serializes to structs. Would you be interested in reviewing it? Performance is ok/good and I personally think usability is good as well :) https://github.com/jorgen/json_struct

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.
