vue脚手架基础demo1
目录
bootstrap CSS样式引入
npm i jquery bootstrap@4.6 popper.js -S
在main.js中引入
import 'bootstrap/dist/js/bootstrap.js'
import 'bootstrap/dist/css/bootstrap.css'
在根目录创建【vue.config.js】文件
const webpack = require("webpack")
module.exports = {
// 配置插件参数
configureWebpack: {
plugins: [
// 配置 jQuery 插件的参数
new webpack.ProvidePlugin({
// 引入jquery
$: 'jquery',
jQuery: 'jquery',
'window.jQuery': 'jquery',
// 引入popper.js
Popper: ['popper.js', 'default']
})
]
}
