electron打包整理

最近在折騰把項目打包成桌面應用程序，發現一個工具electron，能夠講項目打包成一個跨平臺的應用程序，很方便，來學習一下。


一、先安裝electron、electron-packager，安裝方法能夠使用package.json文件配置，而後npm install
也能夠使用cnpm安裝，速度會快點，具體以下：
npm install -g cnpm --registry=https://registry.npm.taobao.org
cnpm i

package.json以下：

{
"name": "electron_demo",
"version": "1.0.0",
"main": "main.js",
"scripts": {
"start": "electron .",
"packager": "electron-packager ./ stockschool --platform=win32 --arch=x64 --icon=./pazq.ico --out=./ElectronApp"
},
"devDependencies": {
"electron": "~1.7.8",
"electron-packager": "^10.1.2"
},
"dependencies": {}
}

二、安裝完成後，準備好要打包的項目，並增長一個main.js,用來聲明一個相似webview的東西，來加載頁面。

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: 1366,
        height: 727,
        minWidth: 1366, // Integer (可選) - 窗口的最小寬度, 默認值爲 .
        minHeight: 727, // Integer (可選) - 窗口的最小高度. 默認值爲 .
        maxWidth: 1366, // Integer (可選) - 窗口的最大寬度, 默認無限制.
        maxHeight: 727, // Integer (可選) - 窗口的最大高度, 默認無限制.
        minimizable: true, // Boolean (可選) - 窗口是否能夠最小化. 在 Linux 中無效. 默認值爲 true.
        maximizable: false, // Boolean (可選) - 窗口是否能夠最大化動. 在 Linux 中無效. 默認值爲 true.
        useContentSize: false, // width 和 height 將使用 web 頁面的尺寸
        center: true,  // Boolean (可選) - 窗口在屏幕居中.
    })
    mainWindow.setMenu(null)

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

    // Open the DevTools. // 打開開發工具 mainWindow.openDevTools();
    // 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.

三、啓動項目：
npm start

四、打包，根據平臺打包成一個.exe文件。（導出目錄見 package.json中的out配置項）
打包方法：cnpm run packager
package.json中的打包配置
electron-packager <應用目錄> <應用名稱> <打包平臺> --out <輸出目錄> <架構> <應用版本>

electron-packager . HelloWorld --platform=win32 --arch=x64 --icon=./pazq.ico --out=./ElectronApp --version=0.0.1
