Webpack-dev-server serves a directory list instead of the app page

问题

I can only see the actual app under /public.

The configs in webpack.config.js are below:

var path    = require('path');
var webpack = require('webpack');

module.exports = {

  entry: [
    'webpack-dev-server/client?http://localhost:8080',
    'webpack/hot/only-dev-server',
    './app/js/App.js'
],

  output: {
    path: path.join(__dirname, 'public'),
    filename: 'bundle.js',
    publicPath: 'http://localhost:8080'
  },

  module: {
    loaders: [
      {
        test: /\.js$/,
        loaders: ['react-hot', 'babel-loader'],
        exclude: /node_modules/
      }
     ]
   },

  plugins: [
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoErrorsPlugin()
  ]

};

The project hierarchy is:

• app

  • js

• node_modules

• public

  • css

  • img

  bundle.js

  index.html

• package.json

• webpack.config.js

How can I modify to make sure the http://localhost:8080/ entry is for the application per se?

回答1:

If you're using webpack's dev server you can pass in options to use /public as a base directory.

devServer: {
    publicPath: "/",
    contentBase: "./public",
    hot: true
},

See the webpack configuration docs, and specifically the webpack dev server docs for more options and general information.

You can also add the --content-base flag to your start-up script, e.g.

    "scripts": {
        "start:dev": "webpack-dev-server --inline --content-base ./public"
    }

In my case, I misspelled 'index.html' when I set up the HTMLWebpackPlugin. Double check your filenames if you're using this plugin.

var HTMLWebpackPlugin = require('html-webpack-plugin');
var HTMLWebpackPluginConfig = new HTMLWebpackPlugin({
  template: __dirname + '/app/index.html',
  filename: 'index.html',
  inject: 'body'
});

I had accidently removed index.html and then I got only the directory list.
