How can I integrate notification channels into my app?

You can integrate notification channels by using APIs provided by services like Twilio or Firebase. What platform are you using?

I'm using a web application with Node.js.

Great! For Node.js, you can use libraries like 'node-notifier' for desktop notifications or integrate with Firebase for push notifications.

Can you show me a code example for Firebase?

Sure! Here's a simple example:

const admin = require('firebase-admin');

admin.initializeApp();

const message = {
  notification: {
    title: 'Hello!',
    body: 'This is a notification.'
  },
  token: '<USER_DEVICE_TOKEN>'
};

admin.messaging().send(message)
  .then((response) => {
    console.log('Successfully sent message:', response);
  })
  .catch((error) => {
    console.log('Error sending message:', error);
  });
