Why Push notifications with FCM in React Native? - Purpose & Use Cases

The Big Idea

What if your app could whisper important news to users exactly when they need it, without them opening it?

The Scenario

Imagine you want to send a message to your app users whenever there is a new update or offer. Without a system, you would have to ask users to open the app constantly to check for news.

The Problem

This manual way is slow and annoying. Users might miss important info or get tired of checking. Also, sending messages one by one to each user is very hard and takes a lot of time.

The Solution

Push notifications with FCM (Firebase Cloud Messaging) let your app receive messages instantly, even when it is closed. FCM handles sending messages to many users easily and reliably.

Before vs After

✗ Before

Check server for updates every minute; show alert if new update found

✓ After

Use FCM to receive push notification instantly; show alert on message

What It Enables

With FCM push notifications, your app can talk to users anytime, keeping them informed and engaged without them lifting a finger.

Real Life Example

A shopping app sends a push notification about a flash sale right when it starts, so users don't miss the deal.

Key Takeaways

Manual checking for updates is slow and unreliable.

FCM sends messages instantly to many users at once.

Push notifications keep users engaged and informed effortlessly.
