javascript - webpack-dev-server does not refresh in real time, why

Question

When npm start, open http://localhost:8080/ and modify the js file. Why is it not refreshed in real time?
The port is still the same, there is no real-time refresh, and there is no change after manual refresh

Directory Structure

webpack.config.js

const path = require('path');
const webpack = require("webpack");

module.exports = {
    entry: './src/index.js',
    output: {
        path: path.resolve(__dirname, 'dist'),
        filename: 'foo.bundle.js',
        publicPath: './dist'
    },
    module: {
        rules: [
            {
                test: /\.js$/,
                loader: 'babel-loader',
                exclude: /node_modules/
            }
        ]
    },
    devServer: {
        contentBase: "./",
        historyApiFallback: true,
        hot:true,
        inline: true // 实时刷新
    },
    plugins: [
        new webpack.HotModuleReplacementPlugin()
    ]
};

  "name": "test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",

solved

//修改
//publicPath: './dist' =>  publicPath: '/dist'

Answer 1

publicPath path problem, remove the dot/dist，或使用绝对路径publicPath: 'http://127.0.0.1:8080/examples/build

Answer 2

No refresh or no real-time refresh? Have you enabled nginx reverse proxy?
