<div *ngFor="let item of jsonData">
  {{ item.propertyName }}
</div>

import { Component, OnInit } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.component.html',
  styleUrls: ['./your-component.component.css']
})
export class YourComponent implements OnInit {
  jsonData: any[];

  constructor(private http: HttpClient) { }

  ngOnInit() {
    this.http.get<any[]>('your-firebase-data-url').subscribe(data => {
      this.jsonData = data;
    });
  }
}

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { HttpClientModule } from '@angular/common/http';

import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
