Theprogrammersfirst: How to import and use Tensorflow's DANFO.js library inside an Angular web app?

I am trying to use Tensorflow's DANFO.js library inside an Angular web app (with Ionic component's but that is irelevant).

I simply ran the command: npm install danfojs --save and npm install @tensorflow/tfjs-node --save
I tried all kinds of imports inside an Angular Service like: import 'danfojs';, import { DataFrame } from 'danfojs'; or even according to only related question to this topic I could find:import { DataFrame } from 'danfojs/dist/core/frame';
All of the above examples don't work
I even tried importing the DANFO.js in app.module without any change

And I always get this error message (rest of the error is in edit):

How can I use DANFO.js inside an Angular app (specifically inside an service)?

Edit:

The whole error code gets so long it doesn't fit VS Code terminal (there are just hundreds of errors):
