先 clone Electron 的官方示例 https://github.com/electron/electron-quick-start,对目录结构进行调整,代码放入 src 文件夹中。

在 main.js 中 mainWindow 创建完成后进行窗口最大化 全屏 载入网页,browser-window-focus browser-window-blur 事件中屏蔽快捷键。

载入网页的地址使用配置文件,可以在打包后进行更改,不需要写死在代码中,或者使用 "electron-serve": "^1.1.0", 进行代理前端静态文件,dist 文件夹放入 src 中,这种方式就需要每次进行打包。

// Modules to control application life and create native browser window
const { app, BrowserWindow, globalShortcut } = require('electron')
const path = require('path')
const fs = require('fs')
const serve = require('electron-serve');
const loadURL = serve({ directory: 'src/dist' });

function createWindow() {
  // Create the browser window.
  const mainWindow = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js')
    }
  })

  // 窗口最大化
  mainWindow.maximize();
  // 窗口全屏
  mainWindow.setFullScreen(true)
  // 载入网页
  // mainWindow.loadURL("http://localhost")



  // const envpath = '/root/.DEVICEFRONTENDHOST'
  // if (fs.existsSync(envpath)) {
  //   fs.readFile(envpath, 'utf8', (err, data) => {
  //     if (err) {
  //       console.error(err);
  //       return;
  //     }
  //     mainWindow.loadURL(data.replace("\n", ''))
  //   });
  // } else {
  //   mainWindow.loadFile('src/index.html')
  // }

  if (fs.existsSync('src/dist')) {
    // 代理spa electron-serve
    mainWindow.loadURL('app://-');
    // loadURL(mainWindow);
  } else {
    mainWindow.loadFile('src/index.html')
  }

  // Open the DevTools.
  // mainWindow.webContents.openDevTools()
}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.whenReady().then(() => {
  createWindow()

  app.on('activate', function () {
    // On macOS it's common to re-create a window in the app when the
    // dock icon is clicked and there are no other windows open.
    if (BrowserWindow.getAllWindows().length === 0) createWindow()
  })
})

// Quit when all windows are closed, except on macOS. There, it's common
// for applications and their menu bar to stay active until the user quits
// explicitly with Cmd + Q.
app.on('window-all-closed', function () {
  if (process.platform !== 'darwin') app.quit()
})

// 屏蔽网页刷新快捷键
app.on('browser-window-focus', function () {
  globalShortcut.register("CommandOrControl+R", () => {
    console.log("CommandOrControl+R is pressed: Shortcut Disabled");
  });
  globalShortcut.register("F5", () => {
    console.log("F5 is pressed: Shortcut Disabled");
  });
  globalShortcut.register("F11", () => {
    console.log("F11 is pressed: Shortcut Disabled");
  });
});
app.on('browser-window-blur', function () {
  globalShortcut.unregister('CommandOrControl+R');
  globalShortcut.unregister('F5');
  globalShortcut.unregister('F11');
});

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.

使用 https://www.electronforge.io/ 进行打包,导入现有项目,package.json 中务必配置 author 字段,会自动写入打包配置,但也需要修改。

npm install --save-dev @electron-forge/cli
npm exec --package=@electron-forge/cli -c "electron-forge import"

config forge packageConfig 中会配置名称 图标,每次打包是否覆盖,makers 中会配置不同平台,这里需要删掉 rpm 平台,因为如果不删除,在 jetson arm64 上也会识别成也是linux 会同时打包 deb rpm,就会报错。

"config": {
    "forge": {
      "packagerConfig": {
        "name": "electron_quick_start",
        "icon": "./src/icon/icon.png",
        "overwrite": true
      },
      "makers": [
        {
          "name": "@electron-forge/maker-squirrel",
          "platforms": [
            "windows"
          ],
          "config": {
            "name": "electron_quick_start",
            "icon": "./src/icon/icon.png",
            "overwrite": true
          }
        },
        {
          "name": "@electron-forge/maker-zip",
          "platforms": [
            "darwin"
          ],
          "config": {
            "name": "electron_quick_start",
            "icon": "./src/icon/logo.png",
            "overwrite": true
          }
        },
        {
          "name": "@electron-forge/maker-deb",
          "config": {
            "name": "electron_quick_start",
            "icon": "./src/icon/icon.png",
            "overwrite": true
          }
        }
      ]
    }
  }

最后直接运行 npm run package npm run make 将会自动识别当前机器的平台架构,即可在 out/make 中看到不同平台不同架构的打包成品。
