How to bundle react app with rollup

Question

I am looking for help with rollup config to build simplest react app.

Currently my bundled js file doesn't really bundle any dependency and looks pretty bare bone.

Repo to repro

rollup config file

bundled JS file

My rollup config:

import babel from 'rollup-plugin-babel';
import filesize from 'rollup-plugin-filesize';
import nodeResolve from 'rollup-plugin-node-resolve';
import progress from 'rollup-plugin-progress';
import visualizer from 'rollup-plugin-visualizer';
import commonjs from 'rollup-plugin-commonjs';
import json from 'rollup-plugin-json';

export default {
  input: 'src/index.js',
  output: [
    {
      file: 'dist/index.js',
      format: 'umd',
      globals: {
        react: 'React',
        'react-dom': 'ReactDOM',
        'styletron-react-core': 'StyletronReactCore',
      },
      sourcemap: 'inline',
    },
  ],
  external: ['react', 'react-dom', 'styletron-react-core'],
  plugins: [
    progress(),
    nodeResolve({
      browser: true,
    }),
    json(),
    babel({
      babelrc: false,
      presets: [['es2015', { modules: false }], 'stage-1', 'react'],
      plugins: ['external-helpers'],
    }),
    visualizer(),
    filesize(),
    commonjs({
      include: 'node_modules/**',
    }),
  ],
};

In case someone will run into this: Here is my working rollup configs.

I updated the demo repo as well.

import babel from 'rollup-plugin-babel';
import filesize from 'rollup-plugin-filesize';
import nodeResolve from 'rollup-plugin-node-resolve';
import progress from 'rollup-plugin-progress';
import visualizer from 'rollup-plugin-visualizer';
import commonjs from 'rollup-plugin-commonjs';
import json from 'rollup-plugin-json';
import replace from 'rollup-plugin-replace';

export default {
  input: 'src/index.js',
  output: [
    {
      file: 'dist/index.js',
      format: 'umd',
      sourcemap: 'inline',
    },
  ],
  plugins: [
    progress(),
    nodeResolve({
      browser: true,
    }),
    json(),
    commonjs({
      include: [
        'node_modules/**',
      ],
      exclude: [
        'node_modules/process-es6/**',
      ],
      namedExports: {
        'node_modules/react/index.js': ['Children', 'Component', 'PropTypes', 'createElement'],
        'node_modules/react-dom/index.js': ['render'],
      },
    }),
    babel({
      babelrc: false,
      presets: [['es2015', { modules: false }], 'stage-1', 'react'],
      plugins: ['external-helpers'],
    }),
    visualizer(),
    filesize(),
    replace({
      'process.env.NODE_ENV': JSON.stringify('production'),
    }),
  ],
};

My original problem was assuming React dependency was external. This is correct for the component libraries but not for standalone app. I also had to fix some minor problems and named imports mapping.

Hope this will save somebody some time.
