rollup split lib and app

readme.md

intentionally not using .babelrc

app.js

import * as Lib from 'lib';

console.log('APP');
console.log(Lib);

lib.js

// used as entry point to build the common lib
console.log('LIB ENTRY POINT');

import { a, b } from 'lib';

export default { a, b };

rollup.app.js

import { rollup } from 'rollup';
import npm from 'rollup-plugin-npm';
import commonjs from 'rollup-plugin-commonjs';
import babel from 'rollup-plugin-babel';

rollup({
  'entry': 'app.js',
  'external': ['lib'],
  'plugins': [
    npm({ 'jsnext': true, 'main': true/*, skip: ['lib']*/}),
    commonjs(),

.then( bundle => bundle.write({
  'banner': '/* APP */',

  'format': 'iife',
  'globals': {
    'lib': 'Lib'
  },
  'sourceMap': true
}) )
.catch( error => console.log(error) );

rollup.lib.js

import { rollup } from 'rollup';
import npm from 'rollup-plugin-npm';
import commonjs from 'rollup-plugin-commonjs';
import babel from 'rollup-plugin-babel';
// import uglify from 'rollup-plugin-uglify';

rollup({
  'entry': 'lib.js',
  'plugins': [
    babel({ 'babelrc': false, 'presets': ['es2015-rollup'] }),
    npm({ 'jsnext': true, 'main': true}),
    commonjs()
    // uglify()
  ]
})
.then( bundle => bundle.write({
  'dest': 'build/lib.js',
  // 'exports': 'named',
  'format': 'iife',
  'moduleName': 'Lib',
  'banner': '/* Lib */',
  'sourceMap': true
}) )
.catch( error => console.log(error) );

Is it necessary to run rollup.app.js and rollup.lib.js inside babel-node?
