Appery.io Server Code allows to quickly write any custom app logic using JavaScript and expose is via a REST API. Here is an example invoking Uber API, and example accessing the cloud database and scheduling the script to run periodically.

The Server Code script JavaScript API also enables you to send a push notification in just one line of code (well, 3 lines of code). After you configure push notifications, this is how to send a message to all users who installed the app:

[code language=”JavaScript” title=”Sending push notification from Server Code:”]
PN.send("07a6350d-d563-3902-9aba-589ca6ab7876", {
"message": "Hi, there!")
});
[/code]

Once you configure push, you will have a Push API key which you set above and then just the push message. This code will send a message to all the users who installed the app. There is also an option to send a targeted push message, only to some users.

Any script is automatically exposed via a REST API so you can quickly invoke it from an app. If you need to customize your app and build custom APIs – Server Code script is what you need.
