Firebase Flashcards For Beginners

Cloud Firestore is a NoSQL cloud database that offers more advanced querying and data modeling capabilities, as well as better scalability and performance for larger datasets.

Firebase offers a range of services, including real-time databases, authentication, cloud storage, hosting, cloud functions, and more.

Firebase Cloud Storage is a service that allows you to store and serve user-generated content, such as images and videos, in the cloud

The Realtime Database is a NoSQL cloud database that allows you to store and sync data in real time

Firebase is a Backend-as-a-Service (BaaS) platform that provides developers with a set of tools and services to build and scale mobile and web applications quickly and easily.

Firebase Authentication is a service that provides easy-to-use authentication APIs and ready-made UI libraries to authenticate users with their email and password, Google, Facebook, Twitter, and more.

Firebase Performance Monitoring is a service that provides real-time insights into your app's performance, such as network latency, app startup time, and more.

1. Offline testing: Firebase emulators allow you to test your app's functionality even when you don't have an internet connection, which is useful for testing in environments where internet access is unreliable.
2. Faster testing: With Firebase emulators, you can run your tests much faster than you would with live Firebase servers. This is because the emulators are running locally on your machine, which eliminates network latency and other factors that can slow down your tests.
3. Cost-effective: Using Firebase emulators can help you save money by reducing your reliance on live Firebase servers, which can be expensive, especially for larger projects.
4. Customization: Firebase emulators allow you to customize the testing environment to suit your specific needs, such as using a different data set or tweaking configuration settings.
5. Security: Testing with Firebase emulators is a safer option as it eliminates the risk of accidentally exposing sensitive data or making changes to live data.

Firebase Analytics is a service that provides insight into your app's usage and user behavior, such as user demographics, user engagement, and more.

The Firebase SDK is a set of libraries that allows you to integrate Firebase services into your web application.

Firebase emulators are local, lightweight versions of Firebase services that allow you to test your app's integration with Firebase without accessing the live Firebase servers.

Firebase Crashlytics is a service that provides real-time crash reporting and analysis for your app.

Firebase Hosting is a fast and secure way to host your web app, static and dynamic content, and deploy it globally with a single command.

You can initialize Firebase by calling the firebase.initializeApp() function and passing in your Firebase configuration object.

The Firebase configuration object contains the configuration settings for your Firebase project, such as your project ID and API key.

A Firebase App is a specific instance of your application that is associated with a unique identifier or App ID. An App ID is a unique identifier used to identify your application in Firebase. A Firebase App can be created for each platform (iOS, Android, and web) that your application supports.

A Firebase Project is a container for all Firebase resources and services. A Firebase Project can have multiple Firebase Apps associated with it. You can create a Firebase Project by visiting the Firebase console and creating a new project. Each Firebase Project has a unique Project ID that identifies the project.

Firebase Security Rules allow you to control access to your data and protect it from unauthorized access.

Step One: 

Create Firebase project and register app. 

To integrate Firebase into your JavaScript app, you must first create a Firebase project and then register your app with that project. During the registration process, Firebase provides you with a configuration object that you will need to connect your app with your Firebase project resources. This configuration object contains all the necessary information to establish a secure connection between your app and Firebase services.

Step Two:

Install the SDK and initialize Firebase.

Install via NPM:

npm install firebase

Initialize Firebase in your app:

import { initializeApp } from 'firebase/app';

// TODO: Replace the following with your app's Firebase project configuration
const firebaseConfig = {
  //...
};

const app = initializeApp(firebaseConfig);

Step Three:

Access Firebase in your app:

import { initializeApp } from 'firebase/app';
import { getFirestore, collection, getDocs } from 'firebase/firestore/lite';
// Follow this pattern to import other Firebase services
// import { } from 'firebase/<service>';

// TODO: Replace the following with your app's Firebase project configuration
const firebaseConfig = {
  //...
};

const app = initializeApp(firebaseConfig);
const db = getFirestore(app);

// Get a list of cities from your database
async function getCities(db) {
  const citiesCol = collection(db, 'cities');
  const citySnapshot = await getDocs(citiesCol);
  const cityList = citySnapshot.docs.map(doc => doc.data());
  return cityList;
}

Firebase Cloud Functions are serverless functions that allow you to run backend code without managing servers.

The Firebase console is a web-based interface that allows you to manage your Firebase project, including authentication, databases, storage, hosting, functions, and more.

Firebase Test Lab is a service that allows you to run automated tests on real devices to ensure your app works correctly on different configurations and devices.
