  Server Side API

Secure your ports, the zip has basic middleware but you need to wire it up yourself as I'm using libenvpp for configuration instead of the default setup, I also use SPDLOG if you want you can wire your own logger in the API.cpp file.

 Why?

Have you ever wanted to ditch the old API because you don't like TCP? Me too! Now you can do it with this

Requirements

• CrowCpp/Crow

Installing requirements (Using vcpkg and CMake)

Run command.

vcpkg install crow

To get proper status on startup you need to start your game cores AFTER the db NEVER BEFORE OR AT THE SAME TIME

Below there's an example for people using the Metin2 on LINUX project

In your docker-compose.yml or compose.yml

Add ports (18080) to your db service as well as the healthcheck, example below:

  db:
    image: ${GAME_IMAGE}
    restart: always
    env_file:
      - .env
    expose:
      - ${DB_PORT}
    ports:
      - "18080:18080"
    command: db
    volumes:
      - ./storage/log/db/:/app/log/
    depends_on:
      database:
        condition: service_healthy
    healthcheck:
      test: "curl --silent --fail http://${API_USERNAME}:${API_PASSWORD}@localhost:18080/status > /dev/null || exit 1"
      interval: 10s
      timeout: 5s
      retries: 5
    networks:
      - metin2

And all your cores should have db with service_healthy for your dependencies, example below

  ch1_first:
    image: ${GAME_IMAGE}
    restart: always
    environment:
      GAME_HOSTNAME: ch1_first
      GAME_CHANNEL: 1
      GAME_MARK_SERVER: true
      GAME_PORT: 13000
      GAME_P2P_PORT: 14000
      GAME_MAP_ALLOW: 1 3 4 5 6 21 23 24 25 26 41 43 44 45 46 91 92 93 107 112 201
    env_file:
      - .env
    expose:
      - 13000
      - 14000
    ports:
      - "13000:13000"
    command: game
    volumes:
      - ./storage/log/ch1/first/:/app/log/
      - ./storage/mark/:/app/mark/
    depends_on:
      db:
        condition: service_healthy
    networks:
      - metin2

Usage

There's also a Laravel 12 compatible service in the downloads with the example usage below

    public function __invoke(Request $request)
    {
        $status = (new ServerApiService)->fetchStatus();

        if (! $status) {
            return 'No data';
        }

        return [
            'channels' => $status->getChannels(),
            'userCount' => $status->getUserCount(),
            'shopCount' => $status->getShopCount(),
            'ch1' => $status->getChannel(13000)->value,
        ];
    }
