Firebase cloud functions: Update user profile

Question

In my e-commerce project, I want to use google maps api to insert user's shop location.

I used google cloud functions to insert the latitude, the longitude, and the address.

Now I could insert the data in the collection called locations. But I want to attach those information to the user profile collection.

So how can I insert latitude, longitude, and user address into the user profile collection?

This is my index.js

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();

const Firestore = admin.firestore;
const db = Firestore();

const axios = require("axios");
const cors = require("cors")({
    origin: true
});

const googleMapsApiKey = "AIzaSyAnp23T2tbYj9Ho8uYmcE6W4KnbvZKlEjc";

exports.geocodeAddressAndSave = functions.https.onRequest(async (request, response) => {
    try {
        let address = encodeURI(request.body.address);
        let { data } = await axios.get(
            `https://maps.googleapis.com/maps/api/geocode/json?address=${address}&key=${googleMapsApiKey}`
        );

        if (data.status !== "OK") {
            //no results
            return cors(request, response, () => {
                response.status(200).send("No Results");
            });
        }

        const geocodedLocation = data.results[0];
        const objGeolocation = {
            address: geocodedLocation.formatted_address,
            geoPoint: new admin.firestore.GeoPoint(geocodedLocation.geometry.location.lat, geocodedLocation.geometry.location.lng)
        }

        //firebase

        await 

        db.collection('locations').add(objGeolocation);

        return cors(request, response, () => {
            response.status(200).send(objGeolocation);
        });
    } catch (error) {
        return cors(request, response, () => {
            console.log(error);
            response.status(500).send();
        });
    }
});

Vue.js

I want to insert the data into this collection called Profile.

Answer 1

I changed my vue code.

var user = firebase.auth().currentUser;

      db.collection('Profile').doc(user.uid).update({ 
            address: data.address,
            latitude: data.geoPoint._latitude,
            longitude: data.geoPoint._longitude,
        });

Answer 2

You'll need to know the UID of the user, and then update the user profile with that. If this is a secure operation (it likely is), you'll need to pass the UID in a secure way. See: Getting user info from request to Cloud Function in Firebase

Once you have the UID, you can update the profile document with something like:

db.collection('profiles').doc(uid).update({ ... });
