// app.component.ts
import { Component, OnInit } from '@angular/core';
import { AngularFireAuth } from '@angular/fire/auth';
import { AngularFirestore } from '@angular/fire/firestore';

@Component({
  selector: 'app-root',
  template: `
    <div>
      <h1>Welcome to Angular Firebase!</h1>
      <ul>
        <li><a [routerLink]="['/users']">Users</a></li>
      </ul>
    </div>
  `
