electron入门教程

electron 使用 JavaScript, HTML 和 CSS 构建跨平台的桌面应用

先说下结构如下：

1、首先安装node 下载地址：https://nodejs.org/zh-cn/

2、新建文件夹demo1

3、使用终端进入文件夹 win下在开始--cmd

4、初始化项目

npm init -f // -f它会使用默认只，而不是提示您输入的任何选项。

项目文件夹下会多出package.json文件

5、打开package.json

main：'index.js'修改为 main：'main.js'

6、install electron

npm install electron --save //也可用 cnpm install electron --save

package.json 会加入electron

7、项目根目录下新建main.js

const electron = require('electron')
const path = require("path")
const url = require('url')

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

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.

8、项目根目录下创建index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>
</head>
<body>
    <h1>hello world</h1>
</body>
</html>

9、修改package.json

{
  "name": "demo1",
  "version": "1.0.0",
  "description": "",
  "main": "main.js",
  "scripts": {
    "start": "electron ."
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "electron": "^1.7.10"
  }
}

10、在项目跟目录下终端执行 npm start

如果下面页面打开说明成功

11、打包

打开项目路径

1使用命令 npm install --save-dev electron-packager将electron-package安装到项目的路径下面

注:完成以上两步骤会在 package.json 生成文件

"devDependencies": {
　　"electron-packager": "^8.5.1"
}

3在项目根目录下面的 package.json 里添加类似于如下代码

"scripts": {

os系统:"packageDarwin": "electron-packager . 'Hosts' --platform=darwin --arch=x64 --icon=hosts.icns --out=./dist --asar --app-version=2.0.1",

windows系统:"packageWin": "electron-packager . 'Hosts' --platform=win32 --arch=x64 --icon=hosts.ico --out=./dist --asar --app-version=2.0.1",

linux系统:"packageLinux": "electron-packager . 'Hosts' --platform=linux --arch=x64 --out=./dist --asar --app-version=2.0.1"

}

命令说明：
* location of project：项目所在路径
* name of project：打包的项目名字
* platform：确定了你要构建哪个平台的应用（Windows、Mac 还是 Linux）
* architecture：决定了使用 x86 还是 x64 还是两个架构都用
* electron version：electron-prebuilt 的版本
* optional options：可选选项

PS：这里要注意，字段里的项目名字，version，icon路径要改成自己的；例如:"packager": "electron-packager ~/Desktop/myFirstElectronApp(项目位置) Hello(项目名称) --linux --out ./OutApp(项目导出位置) --version 1.4.13 --overwrite"

4然后，使用命令 npm run-script package---即可打包

注：如果你是mac可以参考我的

{
  "name": "demo1",
  "version": "1.0.0",
  "description": "",
  "main": "main.js",
  "scripts": {
    "start": "electron .",
    "packageDarwin": "electron-packager . 'Hosts' --platform=darwin --arch=x64  --out=./dist --asar --app-version=2.0.1 --ignore=\"(dist|src|docs|.gitignore|LICENSE|README.md|webpack.config*|node_modules)\""
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "electron": "^1.7.10",
　　"electron-packager": "^10.1.0"
  }
}
