I am trying to make a cloud function that sends a push notification to a given user. The user makes some changes and the data is added/updated under a node in firebase database (The node represents an user id). Here i want to trigger a function that sends a push notification to the user. I have the following structure for the users in DB. 1. Overview. In this codelab, you'll learn how to use Cloud Functions for Firebase to add functionality to a chat web app by sending notifications to users of the chat app. This codelab is meant as a sequel to the Firebase Web Codelab, in which you learn how to build a chat app using the Firebase Web SDK. If you would like to learn how to use.

You can send notification messages to drive user re-engagement and retention. When you deploy your function: The Firebase CLI creates a .zip archive of the function code, which is then uploaded to a Cloud Storage bucket (prefixed with gcf-sources) before Cloud Functions creates an Artifact Registry repository (named gcf-artifacts) in your project. Cloud Build retrieves the function code and builds the function source. While it's expected that Firebase apps will use Cloud Functions in unique ways to meet their unique requirements, typical use cases might fall into these areas: Notify users when something interesting happens.

First we're going to need a few things: expo-server-sdk - we'll use this in our cloud functions to actually send the Push Notification. expo-notifications to register our users and app for push notifications. expo-device to make sure we're running this code on a physical device. expo-linking to open Settings in case the user rejects our Push.
What can you do with Cloud Functions? Cloud Functions for Firebase
The APIs changed since the beta release years ago. Update your code to the newer signatures as shown in the documentation for Firestore triggers. Triggers now receive two arguments instead of one. exports.sendNotification = functions.firestore.document ("Buyers/ {userID}/Notifications/ {notificationId}") .onWrite ( (change, context) => { const. Let's create and deploy our cloud function! Create a new folder and run firebase init functions in cmd. Select your Firebase project and be sure to install dependencies with npm. Also, run npm install https as you will need it to make API calls. We will make use of Javascript to write our cloud functions.
Let's create a file inside the project directory called push-notification.js. Inside the file, let's create a function that initializes Firebase and passes the keys of your project. import firebase from 'firebase'; export const initializeFirebase = () => { firebase.initializeApp({ messagingSenderId: "your messagingSenderId" }); } Choose "Cloud Messaging" from the left-hand menu.
