index.html 使用 webpack-dev-server 不重新加载

Question

When I change my app.js and main.css while webpack-dev-server is running, the bundle is updated. But when i change the index.html the content is not refreshed; if I add a line to the HTML, the webpack-dev-server does not refresh anything on the page. Here are my webpack.config.js and package.json files. I hope you can help me.

webpack.config.js :

var webpack = require('webpack');
var WebpackDevServer = require('webpack-dev-server'); 
var CleanWebpackPlugin = require('clean-webpack-plugin'); 
var chalk = require('chalk');  
var env = process.env.WEBPACK_ENV;

var host = 'localhost';
var port = '8080';

var config = {
  devtool: 'source-map',
  entry: [
    'webpack/hot/dev-server',
    'webpack-dev-server/client?http://' + host + ':' + port +'/',
    './src/app.js'
  ],
  output: {
    path: __dirname + '/dist',
    filename: 'bundle.js'
  },
  module : {
    loaders: [
      { test: /\.css$/, loader: 'style-loader!css-loader' },
      { test: /\.html$/,loader: 'file?name=[name].[ext]' }
    ]
  },
  plugins: [
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoErrorsPlugin(),
    new CleanWebpackPlugin(['dist'], {
      root: __dirname,
      verbose: true,
      dry: false
    })
  ]
};

if (env === 'dev') {
  new WebpackDevServer(webpack(config), {
    contentBase: './dist/',
    stats: {colors: true},
    hot: true,
    debug: true
  }).listen(port, host, function (err, result) {
    if (err) {
      console.log(err);
    }
  });

  console.log('-------------------------');
  console.log(chalk.bold.white('Local web server runs at ') + chalk.green('http://' + host + ':' + port));
  console.log('-------------------------\n\n');
}

module.exports = config;

package.json :

{
  "name": "webpack-skeleton",
  "version": "1.0.0",
  "description": "webpack skeleton",
  "main": "bundle.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "WEBPACK_ENV=dev ./node_modules/.bin/webpack --watch --inline"
  },
  "author": "Jose Roa",
  "license": "ISC",
  "devDependencies": {
    "chalk": "^1.1.3",
    "clean-webpack-plugin": "^0.1.9",
    "css-loader": "^0.23.1",
    "file-loader": "^0.8.5",
    "style-loader": "^0.13.1",
    "webpack": "^1.13.0",
    "webpack-dev-server": "^1.14.1"
  }
}

My directory structure:

css  
  main.css
dist
  bundle.js
  bundle.js.map
  index.html
node_modules
src
  app.js
  sum.js
package.json
index.html
node_modules
webpack.config.js

Every file inside the dist directory is generated by webpack.

Answer 1

add the HtmlWebpackPlugin link: https://www.npmjs.com/package/html-webpack-plugin add

// webpack.config.js
const HtmlWebpackPlugin =  require('html-webpack-plugin');
module.exports = {
    plugins: [
        new HtmlWebpackPlugin({
            template: './index.html'
        })
    ]
};

It can be due to your IDE -- see webpack dev server

Working with editors/IDEs supporting “safe write”... This behaviour causes file watcher to lose the track because the original file is removed. In order to prevent this issue, you have to disable “safe write” feature in your editor.

You can try this workaround for auto reloading while developing an app. Add to your entry point ('./src/app.js'):

require('../index.html'); //workround to reload page on index.html changes
