mac版安装

1. 先安装node.js
   2.通过命令行安装
   3.安装代码

//安装测试运行工具：
npm install electron -g
//安装打包工具
npm install -g electron-packager
//模版
npm install -g electron-forge

建立一个项目

A. electron-forge模版创建

electron-forge init {你的app名字}

B.手动创建

1. 建立一个文件夹
2. 在文件夹下放三个文件或用命令行创建三个文件

touch main.js && touch package.json && touch index.html

3.在package.json中写入

{
  "name"    : "应用名称",
  "version" : "0.0.1",
  "description": "简单描述",
  "main"    : "main.js",
  "homepage": ".",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "electron ."
  },
  "author": "作者",
  "license": "ISC"
}

4.main.js中写入如下代码

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

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let win

function createWindow () {
  // Create the browser window.
  win = new BrowserWindow({width: 800, height: 600})

  // and load the index.html of the app.
  win.loadURL(url.format({
    pathname: path.join(__dirname, 'index.html'),
    protocol: 'file:',
    slashes: true
  }))

  // Open the DevTools.
  win.webContents.openDevTools()

  // Emitted when the window is closed.
  win.on('closed', () => {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    win = null
  })

  win.on('resize',() => {
      win.reload();
  })
}

// 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.on('ready', createWindow)

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

app.on('activate', () => {
  // 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 (win === null) {
    createWindow()
  }
})

// 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.

5.在当前目录下运行效果

electron .

打包

electron-packager . appName --mac --out ./输出目录 --arch=x64 --electron-version={输入你下载的对应版本号}
