How can I eliminate specific text from a string following a designated character in Angular 8 with the help of *ngFor?

Hello everyone, I am new to working with Angular and could use some assistance. I have retrieved data in my application through an API response, which is in the format of an array of objects. I have successfully used *ngFor to iterate over this data. Within the data, there is a field called email. I want to display only the name portion of the email address without including "@gmail.com" or "@yahoo.com". In other words, I only want to display the text up to the '@' symbol. I attempted to achieve this using the split method but was unsure how to implement it within *ngFor. Could someone please provide guidance on how to accomplish this? Below is the HTML code snippet:

<div *ngFor="let content of listContent.content">
  <p>{{content.email}}</p>
  <p>{{content.name}}</p>
</div>
The TypeScript code snippet is as follows:
fetchContents() {
  this.MessagesService.findAll(id).subscribe(data => {
    this.listContent = data;
  });
}
I need to manipulate the email text before displaying it in the HTML output.

Answer №1

To achieve this, you will need to utilize special pipes.

Start by creating a custom pipe that will handle the task of removing the domain section from an email address.

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

@Pipe({ name: 'removeDomainFromEmail' })
export class RemoveDomainFromEmailPipe implements PipeTransform {
  transform(value: string): string {
     // Implement logic to strip off the domain part from the value
     return value;
  }
}

Once you have defined your custom pipe, you can use it throughout your application. By importing it correctly into your component, you can incorporate it in your HTML code like so:

<div *ngFor="let content of listContent.content">
  <p>{{content.email | removeDomainFromEmail }}</p>
  <p>{{content.name}}</p>
</div>

Employing pipes offers benefits such as improved scalability and readability for your code.
