介绍

项目入口文件及生命周期

提示

v3.3.0 将 main.js中业务代码，放到了 ./electron/index.js 里面。

这样所有的业务代码都在 ./electron 文件夹下，方便业务统一与全局代码加密。

入口 main.js

该文件只做实例化操作，启动 ElectronEgg

const { ElectronEgg } = require('ee-core');
new ElectronEgg();

生命周期

new ElectronEgg() 实例化会触发 ./electron/index.js 模块，core功能加载顺序如下：

// 引入基础 Application 类
const { Application } = require('ee-core');

class Index extends Application {

  constructor() {
    super();
  }

  /**
   * core app have been loaded
   * 加载
   * config -> service -> controller -> socket -> ready()
   */
  async ready () {
    // do some things
  }

  /**
   * electron app ready
   * 加载以下事件
   * app.on('second-instance')
   * app.whenReady().then() 该事件会创建 mainWindow
   * app.on('window-all-closed')
   * app.on('before-quit')
   * 然后触发
   * -> electronAppReady()
   */
  async electronAppReady () {
    // do some things
  }

  /**
   * main window have been loaded
   * mainWindow 被创建后，加载
   * windowReady() -> addon  -> preload
   */
  async windowReady () {
    // do some things
    // 延迟加载，无白屏
    const winOpt = this.config.windowsOption;
    if (winOpt.show == false) {
      const win = this.electron.mainWindow;
      win.once('ready-to-show', () => {
        win.show();
      })
    }
  }

  /**
   * before app close
   */  
  async beforeClose () {
    // do some things
  }
}

Index.toString = () => '[class Index]';
module.exports = Index;

旧版本

main.js

# 引入框架 Application
const { Application } = require('ee-core');
# 引入 EE 全局对象
const EE = require('ee-core/ee');

# main类
class Main extends Application {

  constructor() {
    super();
    // this对象等于ee框架的全局app对象
  }

  /**
   * core app have been loaded
   * 框架核心功能加载完成
   */
  async ready () {
    // do some things
  }

  /**
   * electron app ready
   * Electron完成初始化，主窗口创建之前
   */
  async electronAppReady () {
    // do some things
  }

  /**
   * main window have been loaded
   * 主窗口创建完成
   */
  async windowReady () {
    // do some things

  }

  /**
   * before app close
   * app退出之前
   */  
  async beforeClose () {
    // do some things

  }
}

// Instantiate an app object
EE.app = new Main();
