json VS cpp-httplib

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 ;)

https://github.com/nlohmann/json works well for me

Here is one popular C++ library (nlohmann/json) removing its use.

Before going into binary serialization I suggest you to get comfortable with serialization to text. You can try to write your data to text files and read them in again. Then after you get an idea of how this works you can try to use a library that writes to XML or json, e.g. nlohmann json

Download the single header file json.hpp from https://github.com/nlohmann/json/releases and place it in your project directory or an include directory.

Exemple of a JSON library: https://github.com/nlohmann/json (For XML, there's tinyxml)

Alternatives at the low to medium level of abstraction include civetweb and mongoose, which have a common ancestor. Both of these appear to be C rather than C++, but seem to be production quality and well-documented. Another C library is cpp-httplib, which is probably too low-level for me.

I use this all the time to expose an admin rest interface to my public installations.

I'm using this one: https://github.com/yhirose/cpp-httplib

Every one of these libraries uses CMake to make it easier for end users to consume their libraries. In fact your example uses CMake as well such that I can consume it the way I describe above.

Through development I've been making requests to my locally hosted sever using cpphttplib via HTTP and always had the intention of using HTTPS once my website was live. Not the smartest idea to leave this until the end, I know.

Have you tried searching the internet? https://github.com/yhirose/cpp-httplib

I'm new to C++, and have been trying to make a simple HTTP request. I stumbled on cpp-httplib and decided to try it out.
