Converting line breaks into a visible string format within Angular

Question

Converting line breaks into a visible string format within Angular

After thorough research, all I've come across are solutions that demonstrate how to display the newline character as a new line.

I specifically aim to exhibit the "\n" as a string within an Angular view. It appears that Angular disregards it by default.

Sample Text:

this.myText = "This is my \n example \n string: \n"

Result of

<div>{{ myText }}</div>

:

"This is my example string:"

Intended Output:

"This is my \n example \n string: \n"

Access Stackblitz for demonstration: HERE

In other words, using

style="white-space: pre-line"

or <pre></pre> or [innerText]="myText" is not the solution I am seeking, as I do not want the \n to be interpreted as a new line.

Your assistance is greatly appreciated!

A different approach that aligns more with Angular practices would involve creating a custom pipe:

.ts:

import { Pipe, PipeTransform } from '@angular/core';

/*
 * Converts newline characters to "\n"
 *
 */
@Pipe({ name: 'newlineAsString' })
export class NewlineAsStringPipe implements PipeTransform {
  
  constructor() {}

 transform(text: string) {
    return text.split('\n').join('\\n');
  }
}

.html:

<div>{{ myText | newlineAsString }}</div>
