1. 快速启动应用程序

# Clone this repository
git clone https://github.com/electron/electron-quick-start
# Go into the repository
cd electron-quick-start
# Install dependencies
npm install
# Run the app
npm start

2. electron安装

mkdir my-electron-app && cd my-electron-app
npm init
npm install --save-dev electron

package.json

{
  "main": "main.js",//入口文件
  "scripts": {
    "start": "electron ."//启动脚本
  },
}

main.js

// Modules to control application life and create native browser window
const { app, BrowserWindow } = require('electron')
const path = require('node:path')

function createWindow () {
  // 1. 创建一个窗口
  // 2. 让窗口加载了一个界面，这个界面就是用web技术实现
  const mainWindow = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js')
    }
  })

  // and load the index.html of the app.
  mainWindow.loadFile('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()
})

// 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.
