push-notification-server | Simple express server that can be | Notification library

push-notification-server is a JavaScript library typically used in Messaging, Notification applications. push-notification-server has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Simple nodejs server using express webserver that can be used as provider of push notifications for both GCM and APNs. APNs stands for Apple Push Notification Service and GCM for Google Cloud Messaging. These services enable us to send push notifications to Android and/or iOS and WatchOS apps. After you have configured and registered your app correctly a 2-way secure connection can be established between your app and the service. GCM and APNs only relay notifications, the notifications themselves have to be created (provided) by a service called the provider. A provider creates and sends a notification based on criteria that you can decide yourself. This could be for instance an incoming chat message, an updated weather forecast, a software update and so on. The provider in this project just sends generic messages. You can send push notifications directly to a specific device, or to a specific topic. In the latter case the notification is sent to all devices that have subscribed to that specific topic. In this example we will focus on notifications that are directly sent to a device. To be able to do this, we need to have a unique device id, and we obtain this as soon as the app registers itself to GCM or APNs. Both services return a token that identifies the app running on that specific device. Our provider service stores these tokens in a PostgreSQL database. Besides the token we also store which service we use to relay the notification: GCM or APNs. You might think that all Apple devices use APNs and all Android devices use GCM, but you can use GCM for Apple devices as well. GCM has a wrapper for the APNs service so you can use GCM for all devices; we will discuss how this is done later. But first we have to set up the server and the database.
