Framework

框架原型

module.exports = class Application {
  constructor(app, data) {
    this.data = data;
    this.app = app;
  }
  // 进程创建周期
  async processCreate() {
    await new Promise((resolve, reject) => {
      setTimeout(() => {
        console.log('worker processWillCreate', Date.now());
        // if (process.pid % 2 === 0) {
        //   return reject(new Error('test error'))
        // }
        resolve();
      }, 2000);
    });
  }
  // 消息接收函数
  processMessage(msg, socket) {
    if (msg.action === 'cluster:ready') {
      console.log('all ready in worker ' + process.pid);
    }
    // console.log('message', msg);
  }
  //进程销毁周期
  async processDestroy() {
    await new Promise((resolve, reject) => {
      setTimeout(() => {
        console.log('worker processDestroy', Date.now());
        resolve();
      }, 2000);
    });
  }
