Writing Data to Cloud Firestore
Writing data to Firestore involves creating documents and collections. Each document is a set of key-value pairs, and collections are containers for documents.
1. Basic Write Operations
Setting Up Firestore in Your App
First, let’s ensure that your app is properly set up to use Firestore. Below are snippets for different platforms:
import { initializeApp } from "firebase/app";
import { getFirestore, collection, doc, setDoc } from "firebase/firestore";
// Your Firebase config object
const firebaseConfig = {
apiKey: "YOUR_API_KEY",
authDomain: "YOUR_PROJECT_ID.firebaseapp.com",
projectId: "YOUR_PROJECT_ID",
storageBucket: "YOUR_PROJECT_ID.appspot.com",
messagingSenderId: "YOUR_SENDER_ID",
appId: "YOUR_APP_ID"
};
// Initialize Firebase
const app = initializeApp(firebaseConfig);
const db = getFirestore(app);
Explanation: This code initializes a Firebase app using the provided configuration object and sets up Firestore as the database for the app. It imports the necessary Firebase modules, configures the app with specific project details, and establishes a connection to Firestore for performing database operations.
