If you want use firebase you must read this article first. First of all you need add firebase to your Ionic project and Installation & Setup in JavaScript initialize the realtime database JavaScript SDK.

Just do npm install firebase

In your app.module.ts create firebase config object: 

// Set the configuration for your app
// TODO: Replace with your project's config object
var config = {
  apiKey: "apiKey",
  authDomain: "projectId.firebaseapp.com",
  databaseURL: "https://databaseName.firebaseio.com",
  storageBucket: "bucket.appspot.com"
};
firebase.initializeApp(config);

// Get a reference to the database service
var database = firebase.database();

You could find all setting in your Firebase console. For more information read Firebase documentation.

After that inside you angular service you could import firebase and do request to database:

import * as firebase from 'firebase';

// Service declaration here
// code here ...

getUsersData() {
    const userId = this.firebase.auth().currentUser.uid;
    return firebase.database().ref('usersProfile')
                            .once('value')        
                            .then(snapshot => snapshot.val())    
                            .then(users => console.log(users));
}
