无法在角度8中使用写入良好的npm模块

Question

I am using Angular 8.2.4. I download the npm module write-good. When I try to use in my test component i am getting error ERROR ReferenceError: match is not defined. Here is the component code.

import { Component, OnInit } from '@angular/core';
import * as  writeGood from 'write-good';

@Component({
  selector: 'app-textnpm',
  templateUrl: './textnpm.component.html',
  styleUrls: ['./textnpm.component.css']
})
export class TextnpmComponent implements OnInit {
  testString: string;
  constructor() { }

  ngOnInit() {
    this.hello();
  }

  public hello() {
    this.testString = writeGood('so so the cat was stolen.');
  }
}

Below is the error details,

Answer 1

To achieve expected result , use below option of using default method of writeGood

public hello() {
    this.testString = writeGood.default('so so the cat was stolen.');
    console.log(this.testString);
  }

Option 2: Use below line for importing write-good

import writeGood = require('write-good');
