中文文档

npm install cherry-pit -g

cherry init

cd cherry
npm install

npm run cherry-connector
npm run cherry-chat
npm run cherry-pk

same as above:

node lib/connector.js 8080
node app.js chat
node app.js pk

or start multi process:

node lib/connector.js 8080
node lib/connector.js 8081
node app.js chat
node app.js chat
node app.js pk
node app.js pk

The same type of process will automatically achieve load balancing, you can also use pm2 for process management.

node test/helper/wsClient2.js
node test/helper/wsClient1.js

config/dev/config.json, busOptions configuration reference here, add your logical server type to gameServerTypes.

{
  "busOptions": {
    "driver": "ioredis",
    "layout": "",
    "redis": [
      "redis://127.0.0.1:6379"
    ]
  },
  "gameServerTypes": [
    "chat",
    "pk"
  ]
}

Add the service directory under service/.

├── service
│   ├── chat
│   │   └── chat.js
│   └── pk
│       └── pk.js

service/chat/chat.js, in the specific service directory to provide the interface.

function talk (gameServer, args) {
  return args;
}

function talk2all (gameServer, args) {
  gameServer.broadcast(args[0]);
  return;
}

function talk2multi (gameServer, args) {
  gameServer.multicast(...args);
  return;
}

module.exports = {
  talk,
  talk2all,
  talk2multi
};

app.js is the entrance, import interface. The return value can be either promise or primitive type.

const chat = require('./service/chat/chat');
const pk = require('./service/pk/pk');

let result;
try {
  switch (serverType) {
    case 'chat':
      result = chat[func](gameServer, args);
      break;
    case 'pk':
      result = pk[func](gameServer, args);
      break;
  }
}
catch (err) {
  console.error(err);
}
