How can I log errors in Angular CLI?

You can log errors in Angular CLI by using the built-in logging service. You can import it and use methods like log, error, and warn.

Can you show me an example of how to implement this?

Sure! First, import the Logger service from @angular/core. Then, you can use it in your component like this:

import { Component } from '@angular/core';
import { Logger } from '@angular/core';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
})
export class MyComponent {
  constructor(private logger: Logger) {}

  someMethod() {
    try {
      // some code that may throw an error
    } catch (error) {
      this.logger.error('An error occurred:', error);
    }
  }
}

What if I want to log errors to an external service?

You can create a custom logging service that sends logs to an external service like Sentry or Loggly. You would inject this service into your components and use it to log errors.
