Angular Universal (Server side rendering) - how use *.umd.js for node.js

When I launch my application with angular universal
i use this repo: https://github.com/evertonrobertoauler/cli-universal-demo

```
$ node dist/server.js
~/api-lib/index.js:1
(function (exports, require, module, __filename, __dirname) { import { Component, Directive, ElementRef, Injectable, NgModule, Pipe } from '@angular/core';
^^^^^^

SyntaxError: Unexpected token import

```

I see that when run build, lib is created in es2015
As in the file` tsconfig.es5.json` we have `"module": "es2015"`

But in the file `api-lib.umd.js` - this is what I need

In my application, I connect the library like this
`import {SampleModule, SampleService} from 'api-lib';`

There is a solution in my project to make webpack compile into es5
In `webpack.config.js`

```
externals: [nodeExternals({
whitelist: [
/^api-lib/
]
})],
```

But it seems to me not right,
I do not understand how I can get my application to connect
here is the `api-lib.umd.js` file when compiled
Or should it automatically do this?
