Current behavior Using rollup with module importing NgxDatatableModule fails due to missing exports.

Warning: 'default' is imported from external module 'rollup' but never used
'ScrollbarHelper' is not exported by 'node_modules\@swimlane\ngx-datatable\release\services\scrollbar-helper.service.js'
'NgxDatatableModule' is not exported by 'node_modules\@swimlane\ngx-datatable\release\datatable.module.js'
'NgxDatatableModule' is not exported by 'node_modules\@swimlane\ngx-datatable\release\datatable.module.js'
'ScrollbarHelper' is not exported by 'node_modules\@swimlane\ngx-datatable\release\services\scrollbar-helper.service.js'
Error: 'NgxDatatableModule' is not exported by node_modules\@swimlane\ngx-datatable\release\index.js

Expected behavior Rollup completes as normal.

Reproduction of the problem Include NgxDatatableModule in your module which is used by rollup.

What is the motivation / use case for changing the behavior? Would like to use this in production.

Please tell us about your environment: Windows 10, NPM 4.2, Node 7.9

• Table version: 9.0.0

• Angular version: 4.0

• Browser: N/A

• Language: Typescript 2.3

In the commonjs plugin you can add the namedExports option, where you can add missing exports. https://github.com/rollup/rollup-plugin-commonjs#custom-named-exports Here my rollup-config.js:

import nodeResolve from 'rollup-plugin-node-resolve';
import commonjs    from 'rollup-plugin-commonjs';
import uglify      from 'rollup-plugin-uglify';

export default {

  entry: 'src/main.js',
  dest: '../build.js', // output a single application bundle
  sourceMap: true,
  format: 'iife',
  onwarn: function(warning) {
    // Skip certain warnings

    // should intercept ... but doesn't in some rollup versions
    if ( warning.code === 'THIS_IS_UNDEFINED' ) { return; }

    // console.warn everything else
    console.warn( warning.message );
  },
  plugins: [
      nodeResolve({jsnext: true, module: true}),
      commonjs({
        namedExports: {
          'node_modules/@swimlane/ngx-datatable/release/index.js': ['NgxDatatableModule']
        },
        include: 
        ['node_modules/rxjs/**', 
        'node_modules/@swimlane/**']
      }),
      uglify()
  ]
};
