javascript - React, Webpack: bundle.js is not generated - Stack Overflow

Edit: The reason was that I was running webpack-dev-server, when running just webpack it worked.

I am using React and Webpack. The bundle.js is not generated. I found this question on SO that brought up the same issue, but I seem to have the required dependencies installed. Here is my webpack.config.js:

var webpack = require('webpack');    
module.exports = {
    entry: [
        'webpack-dev-server/client?http://localhost:8080',
        'webpack/hot/only-dev-server',
        './src/index.js'
    ],
    module: {
        loaders: [{
            test: /\.js?$/,
            exclude: /node_modules/,
            loader: 'react-hot!babel'
        }]
    },
    resolve: {
        extensions: ['', '.js']
    },
    output: {
        path: 'dist',
        publicPath: '/',
        filename: 'bundle.js'
    },
    devServer: {
        contentBase: './dist',
        hot: true
    },
    plugins: [
        new webpack.HotModuleReplacementPlugin()
    ]
};

Here is my package.json:

{
  "name": "plump",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },

    "react": "^15.0.1",
    "react-dom": "^15.0.1",
    "react-router": "^2.4.0"
  }
}

Any idea?

Theres probably something wrong with the output path .. can you try replacing the output path to ./dist

It is due to missing of some key-value pairs in scripts of package.json. Replace your scripts object with the following:

"scripts": {
    "start": "npm run build",
    "build": "webpack -p && webpack-dev-server"
  },

"-p" means specially for production evnvironment of webpack.config.js. Then run this cmd: $ npm start

$ npm start will invoke npm run build cmd which in turn will invoke "webpack -p && webpack-dev-server"
