安装webpack-dev-server html-webpack-plugin

webpack-dev-server html-webpack-plugin

  安装成功后在根目录下创建index.html文件

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>前端设计模式</title>
</head>
<body>
    <p>前端设计模式</p>
</body>
</html>

  修改webpack.dev.config.js文件

添加

const path = require('path')
const HtmlWebpackPlugin = require('html-webpack-plugin')

  效果如下

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'
        })
    ],
    devServer:{
        contentBase:path.join(__dirname,'./release'),
        open:true,
        port:9000
    }
}

  修改package.json文件

将scripts中的dev修改为

"dev": "webpack-dev-server --config ./webpack.dev.config.js --mode development"

  效果如下:

{
  "name": "jsdesgin",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "dev": "webpack-dev-server --config ./webpack.dev.config.js --mode development"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "html-webpack-plugin": "^3.2.0",
    "webpack": "^4.20.2",
    "webpack-cli": "^3.1.1",
    "webpack-dev-server": "^3.1.9"
  }
}

  做完上述步骤后

在cmd中运行cnpm run dev
