How do I handle errors with routing guards in Angular CLI?

You can handle errors in routing guards by implementing the CanActivate interface and using a try-catch block.

Can you give me an example of a routing guard with error handling?

Sure! Here's a simple example:

import { Injectable } from '@angular/core';
import { CanActivate, Router } from '@angular/router';
import { AuthService } from './auth.service';

@Injectable({ providedIn: 'root' })
export class AuthGuard implements CanActivate {
  constructor(private authService: AuthService, private router: Router) {}

  canActivate(): boolean {
    try {
      if (this.authService.isLoggedIn()) {
        return true;
      } else {
        this.router.navigate(['/login']);
        return false;
      }
    } catch (error) {
      console.error('Error in AuthGuard:', error);
      this.router.navigate(['/error']);
      return false;
    }
  }
}

What should I do if I want to log the errors instead of navigating to an error page?

You can replace the navigation to the error page with a logging service call. For example:

console.error('Error in AuthGuard:', error);
this.loggingService.logError(error);
