React JSX Question

Can't find bundle.js

I know this question has been asked before, but I honestly can't find the answer anywhere-- it appears as if I'm doing everything I should however bundle is not created. So I have this

webpack.config.js
file that's supposed to handle HMR + React, and typescript (with tsx syntax), but it's not creating the bundle. Throws no errors on compilation, and seems to be doing alright, but the bundle returns a 404 when I try to fetch it. Here's my file structure:

someApp/
src/
index.tsx
components/
Hello.tsx
dist/
webpack.config.js
...


And here's my webpack config:

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

module.exports = {
entry: [
'webpack-dev-server/client?http://localhost:3000',
'webpack/hot/only-dev-server',
'./src/index.tsx'
],
output: {
path: path.join(__dirname, '/dist'),
filename: 'bundle.js',
publicPath: '/public/'
},

plugins: [
new webpack.HotModuleReplacementPlugin()
],

devtool: 'eval',

resolve: {
extensions: ['', '.webpack.js', '.web.js', '.ts', '.tsx', '.js']
},

module: {
loaders: [
{
test: /\.tsx?$/,
loaders: [
'react-hot-loader',
'ts-loader'
],
include: path.join(__dirname, '/src')
}
],

preLoaders: [
{ test: /\.js$/, loader: 'source-map-loader' }
]
},
externals: {
'react': 'React',
'react-dom': 'ReactDOM'
},
};


Another strange thing is that I think it might have something to do with executing this through node, since when I just run
webpack
by itself it compiles the bundle. Here's my code for starting up the server:

var webpack = require('webpack');
var WebpackDevServer = require('webpack-dev-server');
var config = require('./webpack.config');

new WebpackDevServer(webpack(config), {
publicPath: config.output.publicPath,
hot: true,
historyApiFallback: true
}).listen(3000, 'localhost', function (err, result) {
if (err) {
return console.log(err)
}

console.log('Listening at http://localhost:3000/')

})


Maybe I'm missing something, but I'm pretty new to webpack so any help would be amazing!

Answer

Thats because webpack-dev-server is serving bundle.js from memory. This is done to make serving bundle.js fast. You can add another webpack config for production that spits out bundle.js to disk

module.exports = {
    entry: './src/index.tsx',
    output: {
        path: path.join(__dirname, 'dist'),
        filename: 'bundle.js',
        publicPath: '/public/'
    },
.
.
.

and all your other modules, just don't include your dev-server

if you want to fetch bundle.js like localhost:3000//..../bundle.js

try this

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

module.exports = {
    entry:'./src/index.tsx',
    output: {
        path: path.join(__dirname, 'dist'),
        filename: 'bundle.js',
        publicPath: '/public/'
    },

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

    devtool: 'eval',

    resolve: {
        extensions: ['', '.webpack.js', '.web.js', '.ts', '.tsx', '.js']
    },

    module: {
        loaders: [
            {
                test: /\.tsx?$/,
                loaders: [
          'react-hot-loader',
          'ts-loader'
        ],
        include: path.join(__dirname, 'src')
            }
        ],

        preLoaders: [
            { test: /\.js$/, loader: 'source-map-loader' }
        ]
    },
    externals: {
        'react': 'React',
        'react-dom': 'ReactDOM'
    },
};

EDIT: If you want to fetch bundle.js

you have to use what is defined in the publicPath: '/public/'. so for you the url you can fetch bundle.js from is this localhost:3000/public/bundle.js
