Electron开发入门1

暑期准备校史知识竞赛，选择的方案 Electron + react.js

Electron概述，组成，及开发体验

React.js介绍

Linux系统下开发环境配置

Step1 安装Node.JS

1	sudo apt-get install node

Linux下Nodejs安装

Step2 安装Electron

~~错误示范~~

1	npm install electron -g

正确示范

//首先安装cnpm
npm install -g cnpm --registry=https://registry.npm.taobao.org

//使用cnpm进行安装，使用方法和npm相同
cnpm install -g electron

通过查阅相关资料，了解到，可能是由于国外镜像不能访问的原因，所以使用国内镜像进行安装。

Electron快速入门

创建一个简单的桌面应用

一个Electron应用的目录结构

your-app/
|—— package.json
|—— main.js
|—— index.html

package.json

{
"name"     :"your-app-name",
"version"  :"0.1.0",
"main"     :"main.js"
}

main.js

const electron = require('electron')
// Module to control application life.
const app = electron.app
// Module to create native browser window.
const BrowserWindow = electron.BrowserWindow

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 mainWindow

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

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

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

  // Emitted when the window is closed.
  mainWindow.on('closed', function () {
    // 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.
    mainWindow = null
  })
}

// 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', function () {
  // On OS X 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', function () {
  // On OS X 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 (mainWindow === 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.

index.html

<!DOCTYPE html>
<html>
 <head>
  <meta charset="UTF-8">
  <title>HELLO WORLD</title>
 </head>
 <body>
  <h1>HELLO WORLD!</h1>
  We are using node <script>document.write(process.versions.chrome)</script>
  and electron <script>document.write(process.versions.electron)</script> 
</body>
</html>

Linux命令

touch hello-world
cd hello-world
touch package.json && touch main.js && touch index.html
//往对应的文件中写入上述代码
electron .

Electron官方文档

main.js中的代码，参照注释也好是不太能理解，毕竟Js没有系统的学习过，有错误的地方欢迎指出
