Cannot deploy my reactjs webpack application on google app engine

Question

I'm trying to deploy my react app which is 100% frontend but running on a webpack server. I need to deploy it to Google app engine as a flexible environment but i got this error after making the gcloud app deploy

sh: 1: webpack: not found
npm ERR! file sh

I've followed this tutorial and all dependencies already installed. Unfortunately, i can't get it works.

Here is my current situation

server.js

 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/');
});

webpack.config.js

'use strict';

var path = require('path');
var webpack = require('webpack');
var env = process.env.NODE_ENV

module.exports = {
  devtool: 'eval',
  entry: [
    'whatwg-fetch',
    'webpack-dev-server/client?http://localhost:3000',
    'webpack/hot/dev-server',
    'babel-polyfill',
    './app/index'
  ],
  output: {
    path: path.join(__dirname, 'dist'),
    filename: 'bundle.js',
    library: 'Redux',
    libraryTarget: 'umd',
    publicPath: '/static/'
  },
  plugins: [
   new webpack.optimize.OccurrenceOrderPlugin(),
    new webpack.HotModuleReplacementPlugin()

  ],
  module: {
    loaders: [
      {  test: /\.js$/,
        loaders: ['babel-loader'], exclude: /node_modules/,
        include: path.join(__dirname, 'app')
      },

      {
            test: /\.json$/,
            loader: 'json'
        },

    {test: /\.scss$/, loader: "style-loader!raw-loader!sass-loader?includePaths[]=" + path.resolve(__dirname, "./node_modules/compass-mixins/lib") + "&includePaths[]=" + path.resolve(__dirname, "./mixins/app_mixins")},
  /*  { test: /\.scss$/, loaders: ['style', 'css', 'sass?includePaths[]=' + path.resolve(__dirname, './node_modules/compass-mixins/lib','raw']}, */
     { test: /\.css$/, loader: "style-loader!css-loader" },
     //{ test: /\.json$/, loader: 'json-loader' },
     { test: /\.(jpe?g|png|gif|svg)$/i,loader:'file'},
     {test: /\.(woff|woff2|ttf|eot)$/, loader: 'file'},
     { test: /\.(png|woff|woff2|eot|ttf|svg)(\?v=[0-9]\.[0-9]\.[0-9])?$/,loader: 'url' }



  ]
  },
  node: {
    fs: 'empty',
    net: 'empty',
    tls: 'empty'
  },

devtool: 'source-map'
};

package.json

"scripts": {
    "start": "node server.js",
    "bundle": "webpack --config webpack.config.js",
    "prestart": "npm run bundle",
    "lint": "eslint src"
  },

What i'm doing wrong.

Thanks for helping

You need to change your scripts. Installing Webpack globally in App Engine is not the best approach, use it directly from node_modules.

First, ensure webpack is in your production dependencies:

npm install --save webpack

Edit your package.json script:

"scripts": {
    "start": "node server.js",
    "bundle": "./node_modules/.bin/webpack --config webpack.config.js",
    "prestart": "npm run bundle"
},

Now a plain npm install in a clean installation will be enough for bundling your application.

Could you show your dependencies in the package.json file?

I had a similar problem running gcloud app deploy

Error: Cannot find module 'webpack-dev-server'
at Function.Module._resolveFilename (module.js:469:15)

I solved the issue moving the given dependency (wepack-dev-server) from devDependencies to dependencies in package.json.

In case somebody else has the same problem I suggest to have look at your dependencies in package.json. dependencies are required to run, devDependencies only to develop, e.g.: unit tests, Coffeescript to Javascript transpilation, minification,
