1. Sending to a Single Device

FCM uses device tokens to target specific instances of your app.

import { Messaging } from '@quatrain/messaging'

async function sendDirectPush(token: string) {
    const fcm = Messaging.getAdapter('push')
    
    await fcm.send({
        token: token,
        notification: {
            title: 'New Message',
            body: 'You have a new message from Alice'
        }
    })
}

2. Sending to a Topic

You can also broadcast messages to any user subscribed to a specific FCM topic.

import { Messaging } from '@quatrain/messaging'

async function broadcastUpdate() {
    const fcm = Messaging.getAdapter('push')
    
    await fcm.send({
        topic: 'news_updates',
        notification: {
            title: 'Breaking News',
            body: 'Check out the latest features in v2.0!'
        }
    })
}
