Updating Data in Firebase Realtime Database daily using Firebase Functions

Question

Im currently working on a project and I want to give percentage of points to every users daily based on their current points available and update the user data in my firebase database. I wanted to add points for my users on a daily basis using firebase functions.

I've looked up several guides on setting up Firebase Functions and right now I'm just not sure how can i update the data.

import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';

admin.initializeApp;

export const helloWorld = functions.https.onRequest(async(request, response) => {
    await updatePoints();
    response.send("Hello from Firebase!")
});


export async function updatePoints(){
    try{
        const db = admin.database();
        const ref = db.ref("Users/{userId}")
        await ref.update({
            "points": "3000"
        });
    }
    catch(err){
        console.log("Error occured:"+err)
    }
}

`{userId}` has no meaning where you use it now. You might want to start with a hardcoded path, like `db.ref("test")` — Frank van Puffelen, Jul 10 '19 at 16:30
in that case... is there a way for me to point to the Users points? — Philip Teng, Jul 11 '19 at 06:37
The UID is not automatically available in a HTTP-triggered function. If you need it, you will have to pass it along. Note that we're well beyond the scope of a single question here. — Frank van Puffelen, Jul 11 '19 at 12:43

The project sounds pretty clear to me. It should be a three step process like this to implement it:

If you get stuck on a specific step along the way, post a question with the minimal complete/standalone code that reproduces where you are stuck.

Hi there, I've attempt to update the points to test out the functions and apparently it does not changes anything – Philip Teng Jul 10 '19 at 09:18
