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 ;)

Someone made a benchmark of serialization libraries in go [1], and I was surprised to see gobs is one of the slowest ones, specially for decoding. I suspect part of the reason is that the API doesn't not allow reusing decoders [2]. From my explorations it seems like both JSON [3], message-pack [4] and CBOR [5] are better alternatives.
By the way, in Go there are a like a million JSON encoders because a lot of things in the std library are not really coded for maximum performance but more for easy of usage, it seems. Perhaps this is the right balance for certain things (ex: the http library, see [6]).
There are also a bunch of libraries that allow you to modify a JSON file "in place", without having to fully deserialize into structs (ex: GJSON/SJSON [7] [8]). This sounds very convenient and more efficient that fully de/serializing if we just need to change the data a little.

Since most of the time would be spent decoding json, you could try to cut this time using https://github.com/bytedance/sonic or https://github.com/json-iterator/go, both are drop-in replacements for the stdlib, sonic is faster.
Project mention: Introducing astjson: Transform and Merge JSON Objects with Unmatched Speed in Go | dev.to | 2023-11-29In this article, I will introduce you to a new package called astjson that I have been working on for the last couple of weeks. It is a Go package that allows you to transform and merge JSON objects with unmatched speed. It is based on the jsonparser package by buger aka Leonid Bugaev and extends it with the ability to transform and merge JSON objects at unparalleled performance.
Hi guys, I know that Hotwire is the sh*t in rails nowadays, but if you were to build an API with rails, which serializer would you use ? I have my eyes on jsonapi-serializer with oj , but I am not sure if that is the best option nowadays. The jsonapi-serializer repo is a bit confusing, regarding which version should I use, same for ActiveModelSerializer to be honest.
I’ve used fastjson when unmarshalling to Structs is inconvenient. https://github.com/valyala/fastjson
On the other hand, I'd like to bring in the json library of my choice, e.g. https://github.com/nlohmann/json or https://github.com/danielaparker/jsoncons. So I'd prefer the web server library provides as little as possible in the way of Json support, and certainly doesn't get in the way of using my library of choice. Similarly, I'd like to use my choice of automatic object serialization.
HG converting AK's files from .json to FlatBuffer has completely destroyed every existing AK wiki because they all relied on directly reading AK's json files to automatically add new entries, if wewe insists on waiting for PRTS to figure out how to read FlatBuffer files then it will take over a week for the module stats to be publicly available;
