How to WRITE, READ, UPDATE and DELETE data with Firebase database using JavaScript 

You deserve so much more love from the YT algorithm... Thank you. Lifesaver.

3 years old and still saving lives like mine right now 😅. Excellent video man, congrats

sir, i had done exactly same coding but everytime its showing 'saved' notification, instead of update or delete & delete function isn't working it just updates that particular user for ex:'test' leaving other columns empty except 'username' column.

sir can you make an admin panel which list all our user, we can add new user, edit user, delete, and update too...

i copied all your process but the data and alert is not reflecting

What's the name of song in background?

you deserve a million subscribers for how simple you made this. Got it down in 9 mins that i couldn't with hours reading Google's documentation. For some reason the onclick kept saying it wasn't defined so i used event listener on the element as a workaround. document.querySelector('#submit').addEventListener('click', () => { let name = document.getElementById('name').value; let email = document.getElementById('email').value; let username = document.getElementById('username').value; firebase.database().ref('user-info/' + username).set({ name: name, username: username, email: email }) })

Heyy melvin, I started watching your videos and they're great. I wanna ask tho, I have this website that has a form and the form uses firebase. Is there to build a page that views all those to fill the form

why is my sdk snippet not appearing.

it doesn't save the data in the database (but it saying saved) can you help me please

I'm so cofused the form doesn't submit anything, I have firebase installed and everything ready, there's even no alert

Nice way to pass time at 0:50 😂
