初识Electron

Electron——使用 JavaScript，HTML 和 CSS 构建跨平台的桌面应用程序

1.安装nodejs

2.创建package.json

npm init

eg:　

{
  "name": "abc",
  "version": "1.0.0",
  "description": "",
  "main": "main.js",
  "scripts": {
    "start": "electron ."
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "electron": "^8.1.1"
  }
}

3.安装Electron

npm install --save-dev electron

注：

　　可以换成淘宝镜像

4.创建第一个Electron应用

main.js

const { app, BrowserWindow } = require('electron')

function createWindow () {   
  // 创建浏览器窗口
  const win = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      nodeIntegration: true
    }
  })
  // 加载应用的 index.html
  win.loadFile('index.html')
  // 打开开发工具
  win.webContents.openDevTools()
}

app.whenReady().then(createWindow)

app.on('window-all-closed', () => {
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

app.on('activate', () => {
  if (BrowserWindow.getAllWindows().length === 0) {
    createWindow()
  }
})

index.html

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <title>Hello World!</title>
    <meta http-equiv="Content-Security-Policy" content="script-src 'self' 'unsafe-inline';" />
  </head>
  <body>
    <h1>Hello World!</h1>
    We are using node <script>document.write(process.versions.node)</script>,
    Chrome <script>document.write(process.versions.chrome)</script>,
    and Electron <script>document.write(process.versions.electron)</script>.
  </body>
</html>
