How can I implement logging in Angular Auth Guards?

You can implement logging in Angular Auth Guards by injecting a logging service into your guard and using it to log authentication attempts.

Can you show me a code example?

Sure! Here's a simple example:

import { Injectable } from '@angular/core';
import { CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot } from '@angular/router';
import { LoggingService } from './logging.service';

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

  canActivate(
    next: ActivatedRouteSnapshot,
    state: RouterStateSnapshot
  ): boolean {
    const isAuthenticated = // your authentication logic;
    this.loggingService.log(`AuthGuard: ${isAuthenticated ? 'Access granted' : 'Access denied'}`);
    return isAuthenticated;
  }
}

What if I want to log additional information?

You can enhance the logging by including more details, such as the user's role or the requested URL. Just modify the log message accordingly.

Thanks! This is really helpful.
