using webpack on server side of nodejs

Question

I\'ve been trying to use webpack with a nodejs application, and the client side is going fine - a reasonably good documentation on their website + links from google search.

Answer 1

A real example with webpack 2.x

I want to highlight the difference from client side config:

1. target: 'node'

2. externals: [nodeExternals()]

for node.js, it doesn't make much sense to bundle node_modules/

3. output.libraryTarget: 'commonjs2'

without this, you cannot require('your-library')

webpack.config.js

import nodeExternals from 'webpack-node-externals'

const config = {
  target: 'node',
  externals: [nodeExternals()],
  entry: {
    'src/index': './src/index.js',
    'test/index': './test/index.js'
  },
  output: {
    path: __dirname,
    filename: '[name].bundle.js',
    libraryTarget: 'commonjs2'
  },
  module: {
    rules: [{
      test: /\.js$/,
      use: {
        loader: 'babel-loader',
        options: {
          presets: [
            ['env', {
              'targets': {
                'node': 'current'
              }
            }]
          ]
        }
      }
    }]
  }
}

export default [config]
