This document discusses using Pusher for push notifications. Pusher allows sending push notifications from a backend server to user interfaces like mobile and desktop apps. It avoids problems with polling by using websockets for real-time notifications. The document explains how to set up Pusher by creating an account and app, and integrating it into server-side code using various languages like Ruby, and client-side code using JavaScript or React Native.

Editor's Notes
- A common method of doing such notifications is to poll a script on the server (using AJAX) on a given interval (perhaps every few seconds), to check if something has happened. However, this can be pretty network intensive, and you often make pointless requests, because nothing has happened.
- Push notifications provide convenience and value to app users. For example, users can receive: Sports scores and news right on their lock screen Utility messages like traffic, weather and ski snow reports Flight check in, change, and connection information For app publishers, push notifications are a way to speak directly to a user. They don't get caught in spam filters, or forgotten in an inbox — click-through rates can be twice as high as email. They can also remind users to use an app, whether the app is open or not. They can also be used to drive actions, such as: Promoting products or offers to increase sales Improving customer experience Converting unknown app users to known customers Sending transactional receipts right away Driving users to other marketing channels, such as social networks
