TypeError: pna.nextTick is not a function using simple-peer in angular 7

Question

I am using simple-peer in angular 7

async ngOnInit() {
    try {
      if (location.hash === '#init') {
        this.peer = new SimplePeer({
          initiator: location.hash === '#init'
        })
      }
      else {
        this.peer = new SimplePeer()
      }

      this.peer.on('signal', function (data) {
        console.log(JSON.stringify(data));
      })

      this.peer.on('data', (data) => {
        console.log('Received Data: ' + data)
      })
    } catch (error) {
      console.log(error)
    }
  }

When angular compiler comes on this event

this.peer.on('data', (data) => {
     console.log('Received Data: ' + data)
})

then it throws error

When I omit this event this error is gone

Note: Package versions are as

simple-peer v9.1.2
NPM v6.5.0
Node v10.14.2

it seems the problem is with node version, which node version? — Fateme Fazli, Dec 16 '18 at 10:10
so try ```$ n lts``` then ```$ npm install -g npm``` then ```$ n stable``` — Fateme Fazli, Dec 16 '18 at 10:13
don't type ```$``` just ```n lts``` then ```npm install -g npm``` then ```n stable``` — Fateme Fazli, Dec 16 '18 at 10:15
@FatemeFazli by the way, `Node v10.14.2` is `LTS` right now. https://nodejs.org/en/ — WasiF, Dec 16 '18 at 10:21
i mean try to change your node version 10.13 or 10.14.0 and test it. — Fateme Fazli, Dec 16 '18 at 10:25
I have tested with `node` versions i.e. `10.14.2`, `10.13.0`, `10.12.0`, `10.11.0`, `9.11.2`, `8.14.0` and `8.11.4` but all in vain. — WasiF, Dec 16 '18 at 12:26

exact same issue solved:

npm i -S process, then add this to polyfill.ts:
import * as process from 'process';
window['process'] = process;

may also install:

npm i -S process-nextick-args
