electron入门教程 - 张书达 - 博客园

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 

复制代码; "复制代码")

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

复制代码; "复制代码")

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

复制代码; "复制代码")

复制代码

"scripts": {

os系统:"packageDarwin": "electron-packager . 'Hosts' --platform=darwin --arch=x64 --icon=hosts.icns --out=./dist --asar --app-version=2.0.1 --ignore=\"(dist|src|docs|.gitignore|LICENSE|README.md|webpack.config*|node_modules)\"",

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 --ignore=\"(dist|src|docs|.gitignore|LICENSE|README.md|webpack.config.js|node_modules)\"",

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 --ignore=\"(dist|src|docs|.gitignore|LICENSE|README.md|webpack.config.js|node_modules)\""

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

}

复制代码

复制代码; "复制代码")

_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
