目录一、所需环境&打包前准备1、安装node.js2、安装electron3、web项目二、打包过程1、打包配置2、安装打包器3、执行打包命令： Electron是由GitHub开发，使用 JavaScript，HTML 和 CSS 构建跨平台的桌面应用程序，可以帮我们把web网页项目直接打包成桌面应用程序。

一、所需环境&打包前准备 1、安装node.js

electron 依赖于node.js 需要安装node.js：安装node(步骤，不是重点，略过）

2、安装electron

dos下，全局安装：

npm install -g electron

检查是否安装成功：

electron -v 3、web项目二、打包过程 1、打包配置

在需要打包的web网页项目根目录下分别新建:main.js、package.json

package.json：在package.json中加入如下内容

{ "name" : "App", // 项目名称 "version" : "0.1.0", "main" : "main.js" // 根目录下的main.js }

main.js：在main.js中加入如下代码

const {app, BrowserWindow} = require('electron') 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 win function createWindow () { // Create the browser window. win = new BrowserWindow({width: 800, height: 600}) // and load the index.html of the app. win.loadURL(url.format({ pathname: path.join(__dirname, 'index.html'), protocol: 'file:', slashes: true })) // Open the DevTools. // win.webContents.openDevTools() // Emitted when the window is closed. win.on('closed', () => { // 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. win = 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', () => { // On macOS 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', () => { // On macOS 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 (win === 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.

注意：在main.js 中的index.html 为你web项目的首页，及入口文件

2、安装打包器

打开 DOS窗口，cd 到你的项目目录下，输入下面命令，全局安装electron打包器

npm install electron-packager -g 3、执行打包命令：

在根目录下执行打包命令：

electron-packager . app --win --out App --arch=x64 --electron-version 1.4.14 --overwrite --ignore=node_modules

打包成功后在根目录下会生成打包好的工程：

打开工程中的应用程序即可运行web项目：
