electron将web应用构建跨平台桌面应用

Electron是由Github开发，用HTML，CSS和JavaScript来构建跨平台桌面应用程序的一个开源库。 Electron通过将Chromium和Node.js合并到同一个运行时环境中，并将其打包为Mac，Windows和Linux系统下的应用来实现这一目的。 本文利用vue-cli快速搭建一个项目说明怎么将一个web应用打包构建成桌面应用的过程 开始 使用npm init初始化项目，配置依赖electron，electron-builder（打包组件），这里如果安装electron或者启动时报错，可以删除node_modules中electron的使用npm i electron@+指定版本即可 { "name": "electron-quick-start", "version": "1.0.0", "description": "A minimal Electron application", "main": "main.js", "scripts": { "start": "electron .", "build_win": "electron-builder --win --x64", "build_mac": "electron-builder --mac --x64" }, "build": { "productName": "vuecli" }, "repository": "https://github.com/electron/electron-quick-start", "keywords": [ "Electron", "quick", "start", "tutorial", "demo" ], "author": "GitHub", "license": "CC0-1.0", "devDependencies": { "electron": "^3.1.0", "electron-builder": "^21.2.0" } } package.json需要注意的参数： ：项目入口文件，文件用于配置启动所需参数 scripts：启动命令 start：开发启动命令 build_win：构建win桌面应用 build_mac：构建macos桌面应用 build：构建应用参数，所有参数参考electron-build productName：应用名称 output：产出目录 main.js 官方例子 // Modules to control application life and create native browser window const {app, BrowserWindow} = require('electron') const path = require('path') // 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, webPreferences: { webSecurity: false } }) // and load the index.html of the app. mainWindow.loadFile('index.html') // 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 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', function () { // 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 (mainWindow === null) createWindow() }) BrowserWindow浏览器代理，设置窗口信息等，mainWindow.loadFile('index.html')引入主页文件，webSecurity设置false可忽略浏览器跨域等，该设置可禁止浏览器同源策略，只能在测试环境使用，如需上线正式环境需另外配置网络代理。 静态文件准备 http请求 在测试环境下，如在main.js中设置了webSecurity为false，接口请求地址可设置为绝对路径（此设置忽略跨域），生产环境需另配网络转发。 路由 需修改的相关静态文件地址为相对路径，vue.config.js配置如下： module.exports = { assetsDir: 'static', publicPath: './' }; 启动npm run build开始打包，打包后的文件在dist中，dist文件夹下的文件全部拷贝到electron的初始化项目的根目录下，运行npm start即可正常访问，npm run build_mac开发打包，完成后在根目录的dist下生成vuecli-1.0.0.dmg的桌面应用安装包 原文地址
