一、安裝以及使用webpack-dev-server工具javascript
1.1安裝webpack-dev-serverhtml
npm i webpack-dev-server html-webpack-plugin --save-dev
1.2修改webpack-dev-config這個配置文件java
const path = require('path') const htmlWebpackPlugin = require('html-webpack-plugin') module.exports = { entry:"./src/index.js", output:{ path:__dirname, filename:"./release/bundle.js" }, plugins:[ new htmlWebpackPlugin({ template:'./index.html' /選擇插入模板的html文件 }) ], devServer:{ contentBase: path.join(__dirname,'./release'), open: true, //自動打開瀏覽器 port: 8000 //打開的端口 } }
1.三、在package.json中修改運行腳本webpack
"scripts": { "test": "echo \"Error: no test specified\" && exit 1", "pack": "webpack-dev-server --config webpack-dev-config.js --mode development" }
當再運行npm run pack 時,就能夠自動打開默認瀏覽器,開啓端口爲loaclhost:8000的端口,而且會將web
<script src=""./release/bundle.js><script>
插入到頁面中npm
