Welcome to part 4 of our React.js & Firebase Mastery series. In this tutorial, we will be focusing on deleting data from the Firebase Realtime Database in a React.js application.

Prerequisites

Before you proceed with this tutorial, make sure you have completed the previous parts of this series where we covered the basics of Firebase Realtime Database and how to perform Create, Read, and Update operations in a React.js application.

Delete Data from Firebase Realtime Database in React.js

In order to delete data from the Firebase Realtime Database in a React.js application, we will need to follow these steps:

1. Get a reference to the database node that contains the data to be deleted.
2. Call the remove() method on the reference to delete the data.

Sample code

Here is a sample code snippet that demonstrates how to delete data from the Firebase Realtime Database in a React.js application:

        
            // Import Firebase
            import firebase from 'firebase/app';
            import 'firebase/database';
            
            // Get a reference to the database node
            const database = firebase.database();
            const dataRef = database.ref('data');

            // Call the remove() method to delete data
            dataRef.remove()
                .then(() => {
                    console.log('Data deleted successfully!');
                })
                .catch((error) => {
                    console.error('Error deleting data:', error);
                });
