Firebase Cloud Function onWrite child value

Question

I am using Firebase Cloud Function to send FCM upon Real-Time Database Triggered event. How can I get the value of a child ('uid') inside of {followerUid}?

exports.sendFollowerNotification = functions.database.ref('/followers/{followedUid}/{followerUid}').onWrite(event => {
  const followerUid = event.params.followerUid;
  const followedUid = event.params.followedUid;

Answer 1

I know exactly what you are looking for...

var uid = event.data.val();
var uid1 = String(uid);

add this uid1 to title or body

const payload = {
      notification: {
        title: paypes
        body:  uid1
      }
    };

I'm not sure I understand what you're trying to do but will take a stab.

If you are looking to access the data of uid inside the node that triggered the function:

var uid = event.data.child("uid").val;

Have a look at the documentation on handling event data.
