1. Introduction

In today's digital age, real-time push notifications are a key element in maximizing user experience. This article explores how to build a real-time push notification system using Deno, Supabase, and Firebase Cloud Messaging (FCM). This article is intended for developers interested in Deno and cloud services.

2. Server Setup using Deno and Supabase

Deno is a modern JavaScript and TypeScript runtime created to overcome the limitations of Node.js. Supabase is an open-source backend service based on PostgreSQL that provides real-time database capabilities. Combining these two technologies allows us to build a robust and flexible backend system.

Code Example: Setting up the Supabase Client

This code demonstrates how to initialize the Supabase client. Here, we utilize Deno's environment variable functionality for secure management of Supabase connection information.

3. Detecting Real-time Database Changes

By leveraging Supabase's Webhook feature, we can instantly detect and react to changes in the database. This allows us to quickly deliver the latest information to users.

Code Example: Defining the Webhook Payload

These interfaces are defined to handle data change events that occur in Supabase. The Post interface defines the structure of post data, and the WebhookPayload defines the structure of the data received from the webhook.

4. Sending Push Notifications using Firebase Cloud Messaging

FCM is a powerful service that allows you to send push notifications across various platforms. By sending notifications from the Deno server through FCM, users can receive immediate updates on new posts or important updates.

Code Example: Sending Push Notifications through FCM

This code illustrates the process of the Deno server using FCM to send push notifications. Here, we obtain the access token required for FCM using a Google service account.

5. Conclusion

Building a real-time push notification system using Deno, Supabase, and FCM is very useful in modern web development. With this system, developers can provide users with immediate information delivery and enhanced interaction. Through the technologies and code examples introduced in this article, developers can gain the knowledge and tools necessary to build their own real-time notification system.
