While it's entirely possible to rely only on internal software for Push Notifications, it does simplify development by utilizing a third-party Push Notification gateway service. We've chosen Boxcar for our demo app not only because it's fast and scalable, but also because it offers an HTTP API that allows us to generate pushes from anything capable of generating an HTTP request (which includes JavaScript, Node.js, and our Oracle database server). Boxcar also provides a PhoneGap SDK that is easy to embed without having to worry about a lot of platform-specific code. Finally, Boxcar also provides a free service tier of up to 200 pushes per minute and a device limit of 100 Android devices and iOS devices. After these limits are reached, the price for the service is based solely on the number of pushes sent per minute. The following steps show how to sign up and begin with your project:
