Question 1

libjson-rpc-cpp vs json-rpc-cxx – which one should I use?

Accepted Answer

Use libjson-rpc-cpp if you need mature, full JSON-RPC 2.0 support with built-in transports like HTTP and Redis. Opt for json-rpc-cxx if you prefer a modern, header-only C++17 library with fewer dependencies, as recommended in the README for newer projects.

Question 2

How to generate stubs for a JSON-RPC server using libjson-rpc-cpp?

Accepted Answer

Run the jsonrpcstub tool with your JSON specification file and flags like --cpp-server to create abstract server classes, then implement the virtual methods, as detailed in the README's step-by-step example.

Question 3

Does libjson-rpc-cpp support WebSocket transport?

Accepted Answer

No, the README lists HTTP, TCP, Redis, and Unix sockets as built-in transports, but WebSocket is not mentioned, so you'd need to implement it customly using the extensible architecture.

Question 4

Can I use libjson-rpc-cpp in a Windows project?

Accepted Answer

Yes, but it requires downloading a pre-compiled installer from the project's website, as native builds are not straightforward like on Linux or macOS, per the installation instructions.

Question 5

What are the performance implications of using this framework?

Accepted Answer

Performance depends on the transport used (e.g., HTTP adds overhead), and the library relies on external dependencies like libmicrohttpd, which may impact latency compared to minimal RPC solutions.

Question 6

Is libjson-rpc-cpp still maintained?

Accepted Answer

The README shows active CI testing and updates, but it promotes a newer alternative, suggesting maintenance might slow down in favor of the header-only version.
