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

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

Can you show me a code example of that?

Sure! Here's a simple example:

import { Injectable } from '@angular/core';
import { CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot, Router } from '@angular/router';

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

  canActivate(
    next: ActivatedRouteSnapshot,
    state: RouterStateSnapshot
  ): boolean {
    try {
      const isAuthenticated = // your authentication logic;
      if (!isAuthenticated) {
        this.router.navigate(['/login']);
        return false;
      }
      return true;
    } catch (error) {
      console.error('Error in route guard:', error);
      this.router.navigate(['/error']);
      return false;
    }
  }
}

What should I do if I want to log the error instead of redirecting?

You can simply replace the redirection logic in the catch block with a logging function. For example:

console.error('Error in route guard:', error);
// Log the error to an external service or console
