Firebase V9 Firestore ADD DATA Using setDoc()

There are two methods that we can use to add document data to the Firebase Version 9 Cloud Firestore.

• addDoc()
• setDoc() → you’re here

Note: Before going further, you’ll need to do three things:

1. Create A Firebase Project from Firebase Console
2. Register an app for Web (JavaScript)
3. Add Firebase SDK to JavaScript Web app

Using the setDoc() method, you can add a document to the Firestore database by creating:

• Auto-generated ID or
• Custom ID

Add Data Using setDoc() With Auto-ID

In order to use the setDoc() method, we need to import three methods from the Firebase Firestore Import Statement.

import { getFirestore, collection, setDoc } from "firebase/firestore";

1. getDatabase() → Firestore database where we want to add data as a document.
2. collection() → Where we want to add collection name and database references.
3. setDoc() → Where we actually pass our data along with the collection name and db references.
