1、安装nodejs
2、用npm全局安装electron(可以不全局安装,后面在项目中安装)
3、创建一个目录my_app,下面创建3个文件:package.json、main.js、index.html
4、编缉index.html内容:
Hello World! Hello World!
We are using node , Chrome , and Electron .
5、编缉main.js内容:
const {app, BrowserWindow,globalShortcut,ipcMain} = 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 winfunction createWindow () { // Create the browser window. win = new BrowserWindow({width: 800, height: 600,resizable:false}) //hide menubar win.setAutoHideMenuBar(true) // and load the index.html of the app. win.loadURL('file://'+__dirname+'/index.html') // 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.
6、编缉package.json内容:
{ "name": "demo_app", "version": "0.1.0", "main": "main.js",}
7、运行
在demo_app目录下,执行electron .
如果没有全局安装electron,可以在目录下执行npm install --save-dev electron. 然后在执行在demo_app/node_modules/.bin/目录下执行electron ../../
--save-dev会在package.json中加入一行:
"devDependencies": {
"electron": "^1.4.15" }8、打包
使用electron-package进行打包,生成目录demo_app_release。
electron-packager ./demo_app --platform=win32 --out ../demo_app_release --version 1.4.13 --overwrite --icon=./images/app.ico
9、脚本与依赖
修改package.json:
{ "name": "demo_app", "version": "0.1.0", "main": "main.js", "scripts": { "start": "electron .", "package": "electron-packager ./ demo_app --platform=win32 --out ../demo_app_release --version 1.4.13 --overwrite --icon=./images/app.ico" }, "author": "gelare", "devDependencies": { "electron": "^1.4.15" }, "dependencies": { "log4js": "^1.1.0" }}
在demo_app目录下
执行npm install会安装依赖,包括electron与log4js。
执行npm start会运行程序。
执行npm run-script package进行打包。
10、快捷键
添加ctrl+q,退出程序,在createWindow函数最后加上:
globalShortcut.unregisterAll(); globalShortcut.register('ctrl+q',function(){ app.quit(); });
注册快捷键向主页面发送事件:
globalShortcut.register('alt+c',()=>{ win.webContents.send('global-shortcut','change'); });
接收与处理事件:
修改index.html,引入脚本:
Hello World! Hello World!
We are using node , Chrome , and Electron .
增加index.js:
const { ipcRenderer, desktopCapturer,} = require('electron');ipcRenderer.on('global-shortcut',(event,arg) => { switch(arg) { case 'change': var body = document.querySelector('body'); body.style.backgroundColor = "lightblue"; break; }})
11、菜单
