Game Rooms C++ SDK

A small C++17 SDK for the Game Rooms protocol. It provides:

• HTTP endpoint helpers for creating rooms, fetching app configs, and looking up a room by code
• ecast-style WebSocket envelope encoding/decoding
• Typed helpers for host/player object and relay operations
• Distinct room-not-found, room-locked, and room-full error classification

Build

cmake -S . -B build
cmake --build build
ctest --test-dir build --output-on-failure

Usage

#include <game_rooms/sdk.hpp>
#include <iostream>

int main() {
  game_rooms::HttpApi api("https://example.com");
  auto create_request = api.build_create_room_request(game_rooms::Json::object({
    {"appId", "fibbage"},
    {"audienceEnabled", true}
  }));

  game_rooms::Session host(game_rooms::Role::host);
  auto message = host.create_object("state", game_rooms::Json::object({
    {"round", 1.0},
    {"prompt", "ready"}
  }));

  std::cout << create_request.path << "\n";
  std::cout << game_rooms::ProtocolCodec::encode(message) << "\n";
}

The SDK is transport-agnostic: use the generated HTTP requests with your preferred HTTP client and send encoded WebSocket envelopes over your preferred WebSocket implementation.
