下面,我们就来进行构建一个hello World项目
一个最基本的 Electron application 需要这些文件:
- `package.json` - 处理应用的以来和说明性信息.
- `main.js` - 入口页面和渲染html页面. 这个文件是应用的 **main process**.--主进程
- `index.html` - 要渲染的页面,这个页面是应用的 **renderer process**--渲染进程.
现在我们进行项目的创建,创建我们所需要的项目,命名为helloworld_electron,然后在项目中创建如下图所示的目录结构
[结构目录](/home/jkwu/图片/Screenshot from 2017-03-26 15-10-53.png)
在文件中的内容分别如下所示:
index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Hello World!</title>
</head>
<body>
<h1>Hello World!</h1>
We are using Node.js <script>document.write(process.versions.node)</script>,
Chromium <script>document.write(process.versions.chrome)</script>,
and Electron <script>document.write(process.versions.electron)</script>.
</body>
</html>
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, './src/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.
package.json
{
"name": "helloworld_electron",
"version": "1.0.0",
"description": "'A test for electron, a desktop tool'",
"main": "main.js",
"scripts": {
"start": "electron ."
},
"author": "jkwu",
"license": "ISC",
"keywords": [
"Electron",
"start",
"demo"
],
"devDependencies": {
"electron": "~1.6.2"
}
}
在实现上面过程之后,我们就能够进行调试,首先我们需要运行命令
npm install
进行安装依赖,也就是安装下面内容:
"devDependencies": {
"electron": "~1.6.2"
}
安装之后,我们就能够通过命令
npm start
来进行启动,如下图所示L:是我的启动结果
通过上面的流程,我们能够实现一个最基本的打包,但是,这还不能够跨平台像一个应用软件一样,那么,我们如何 进行打包成这样?? 具体步骤如下所示: 安装打包依赖:
npm install electron-packager --save-dev
将会安装"electron-packager": "^8.6.0"到依赖库中,这是package.json将会自动变化为下面代码
还有为了方便,我在scripts中直接添加了packager项,主要是运行打包命令
{
"name": "helloworld_electron",
"version": "1.0.0",
"description": "'A test for electron, a desktop tool'",
"main": "main.js",
"scripts": {
"start": "electron .",
"packager": "electron-packager ./ helloworld_electron --linux "
},
"author": "jkwu",
"license": "ISC",
"keywords": [
"Electron",
"start",
"demo"
],
"devDependencies": {
"electron": "~1.6.2",
"electron-packager": "^8.6.0"
}
}
```
最后,我们执行命令
```
npm run packager
```
即可完成打包,打包结果如下图所示,进入文件夹,双击程序就能够正常运行
