Electron
1、搭建
1.1、环境
安装 node 和 npm，建议 node 版本更新为最新版本，避免与 electron 版本不兼容。
# 修改源，避免下载 Electron 依赖失败。
npm config set registry https://registry.npmmirror.com在 C:\Users\username 目录下，修改 .npmrc 文件，添加以下内容
ELECTRON_MIRROR=https://npmmirror.com/mirrors/electron/

1.2、初始化工程
mkdir first-electron
cd first-electron
# 初始化工程
npm init1.3、创建文件
目录结构
first-electron
├─index.html
├─main.js
├─package.json
└preload.js
index.html
<!--index.html-->
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'">

</head>
<body>
<h1>Hello World!</h1>
We are using Node.js <span id="node-version"></span>,
Chromium <span id="chrome-version"></span>,
and Electron <span id="electron-version"></span>.
<!-- You can also require other files to run in this process -->
<script src="./renderer.js"></script>

</html>main.js
// main.js
// Modules to control application life and create native browser window
const { app, BrowserWindow } = require('electron')
const path = require('node:path')
const createWindow = () => {
// Create the browser window.
const mainWindow = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
preload: path.join(__dirname, 'preload.js')
}
})
// and load the index.html of the app.
mainWindow.loadFile('index.html')
// Open the DevTools.
// mainWindow.webContents.openDevTools()
}
// 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.whenReady().then(() => {
createWindow()
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 (BrowserWindow.getAllWindows().length === 0) createWindow()
})
})
// Quit when all windows are closed, except on macOS. There, it's common
// for applications and their menu bar to stay active until the user quits
// explicitly with Cmd + Q.
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') app.quit()
})
// 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.preload.js
// preload.js
// All the Node.js APIs are available in the preload process.
// It has the same sandbox as a Chrome extension.
window.addEventListener('DOMContentLoaded', () => {
const replaceText = (selector, text) => {
const element = document.getElementById(selector)
if (element) element.innerText = text
}
for (const dependency of ['chrome', 'node', 'electron']) {
replaceText(`${dependency}-version`, process.versions[dependency])
}
})1.4、运行
在 package.json 声明命令
{
"scripts": {
"start": "electron ."
}
}# 安装依赖
npm install --save-dev electron
# 运行
npm start
2、打包
npm install --save-dev @electron-forge/cli
npx electron-forge import
# 打包 exe 程序
npm run package 打包前，一定要声明 description 和 author
打包后，就会在工程目录下生成 out 目录，里面包含工程的 exe 程序
