Electron结合React开发桌面应用
环境搭建
前提是安装好npm和nodejs,安装以下开发环境,若安装失败则尝试翻墙或者使用淘宝镜像cnmp
electron环境安装
npm install -g electron-prebuilt npm install -g electron-packager
create-react-app安装
npm install -g create-react-app npm install -g react-scripts ## 创建demo
在要创建工程的目录下使用命令create-react-app projectName创建工程:
create-react-app desktop-demo
安装electron以及增加启动命令:
使用命令npm install -save electron安装electron 在脚本里添加启动命令"electron-start": "electron ."
创建Electron的启动文件main.js
在React项目的根目录创建main.js文件,可以直接拷贝[electron-quick-start](https://github.com/electron/electron-quick-start)仓库里的main.js
package.json文件修改
在React项目中的package.json文件中增加main字段,值为"main.js",几homepage字段 "homepage":"."
修改main.js
修改main.js中的win.loadURL,改为 ```java mainWindow.loadURL(url.format({ pathname: path.join(__dirname, './build/index.html'), protocol: 'file:', slashes: true })) ``` 修改src目录下的APP.js则修改页面内容
运行
在根目录下运行npm run build + npm run electron-start即可看到界面, 报错:npm ERR! desktop-demo@0.1.0 build: `react-scripts build` 运行npm install解决 ## 使用热调试 在main.js文件中将启动页修改为 http://localhost:3000/: mainWindow.loadURL('http://localhost:3000/') 开发时,需要启动两个终端,一个终端启动npm start, 另一个终端启动npm run electron-start,这样在electron中就可以热调试了。 不过编译发布时需要改回从build/index.html,可以在package.json中定义个DEV字段,设置为true/false,然后修改main.js,代码如下: ```java if(pkg.DEV) { win.loadURL("http://localhost:3000/") } else { win.loadURL(url.format({ pathname:path.join(__dirname, './build/index.html'), protocol:'file:', slashes:true })) } ``` 运行npm run electron-start之前,根据需要修改DEV为true/false就行了 ## 代码 最终代码如下
package.json
```java { "name": "desktop-demo", "version": "0.1.0", "private": true, "DEV":false, "main": "main.js", "homepage": ".", "dependencies": { "electron": "^1.7.9", "npm": "^5.4.2", "react": "^16.0.0", "react-dom": "^16.0.0", "react-scripts": "1.0.14" }, "scripts": { "start": "react-scripts start", "build": "react-scripts build", "test": "react-scripts test --env=jsdom", "eject": "react-scripts eject", "electron-start": "electron ." } } ```
main.js:
```java 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') const pkg = require('./package.json') // 引用package.json // 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. if(pkg.DEV) { mainWindow.loadURL("http://localhost:3000/") } else { mainWindow.loadURL(url.format({ pathname:path.join(__dirname, './build/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. ```
