开启一个electron项目
1. npm init -y 创建一个前端工程
- 修改 main 选项为
main.js
{
"name": "electron_demo",
"version": "1.0.0",
"description": "electron_demo",
"main": "main.js",
"author": "lsq",
"license": "ISC"
}
2.安装 electron包
npm install --save-dev electron
- 修改启动脚本
"scripts": {
"start": "electron ."
},
3.新建一个html，作为页面入口
// index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<!-- https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'">
<meta http-equiv="X-Content-Security-Policy" content="default-src 'self'; script-src 'self'">
<title>Hello World!</title>
</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>.
<script src="./renderer.js"></script>
</body>
</html>
4.新建一个main.js,作为整个应用入口
// main.js
const { app, BrowserWindow } = require('electron')
const path = require('path')
function createWindow() {
const win = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
preload: path.join(__dirname, 'preload.js')
}
})
win.loadFile('index.html')
}
app.whenReady().then(() => {
createWindow()
app.on('activate', function () {
if (BrowserWindow.getAllWindows().length === 0) createWindow()
})
})
app.on('window-all-closed', function () {
if (process.platform !== 'darwin') app.quit()
})
5.编写页面预加载脚本
// preload.js
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])
}
})
6.编写页面js
// renderer.js
console.log('hello')
