Electron使用純 JavaScript 語法來調用豐富的原生(操作系統) APIs，從而創建桌面應用。所以，很多 JavaScript 的成熟工具和框架都可以在Electron中配置 。
這次來介紹下UI上面的框架配置，我之前的項目用Bootstrap比較多，所以這裏以Bootstrap爲例。
安裝Bootstrap
npm install bootstrap --save
安裝完成後，package.json如下：
{
"name": "demo",
"version": "1.0.0",
"description": "a Electron Demo Application",
"main": "main.js",
"scripts": {
"start": "electron .",
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "Woods",
"license": "ISC",
"devDependencies": {
"electron": "^9.1.0",
"electron-reloader": "^1.0.1"
},
"dependencies": {
"bootstrap": "^4.5.0",
"jquery": "^3.5.1"
}
}
使用Bootstrap
在index.html中，引入bootstrap的css文件，我們就可以順利的使用Bootstrap的組件了。
<link href="./node_modules/bootstrap/dist/css/bootstrap.min.css" rel="stylesheet">
例如，將官方的Dashboard的示例代碼引入到Electron後的代碼如下：
<meta charset="UTF-8">
<title>Hello World!</title>
<meta http-equiv="Content-Security-Policy" content="script-src 'self' 'unsafe-inline';">
<link href="./node_modules/bootstrap/dist/css/bootstrap.min.css" rel="stylesheet">

我們通過 npm run start 運行我們的Electron項目，就可以看到一個帶有樹形菜單的UI界面了。
