Appery’s Max Katz and Charles Cowens will be hosting a twitter chat for discussion about the #apperyio mobile app platform. We’ll be there to answer your questions, and we’ll have some questions for you, too.

• Q1: What kind of things are you doing with Appery.io that you’d like to share?
• Q2: What are the key improvements you’d like to see in the platform?
• Q3: Do you prefer getting information through videos rather than text?

Come join us:

You can make your existing SQL database RESTful via API Express in just minutes. By exposing your SQL database via REST APIs, you can quickly build a mobile app (or web app) that talks to the database. This is a very common requirement when building enterprise mobile apps. API Express is a very powerful tool, so we’ve created several guides to help you get started. You can watch the video, try the step-by-step tutorial or read more about API Express here.

Over the last two weeks, the Appery.io team has updated a number of docs related to the Database, Server Code and Push Notifications APIs. The new format is more user-friendly, making it easier to read and find information. The overview docs and API reference are now separated. This post summarizes what Appery.io Backend Services APIs are available and how to use them.

With Appery.io visual mapping editor, it’s very fast and simple to map data between the UI and REST API services:

REST API mapping

There are cases where straight mapping might not be enough. In other words, you need to take data from the page and format it before making it input to a REST API. That’s exactly why the visual mapping editors allows to write JavaScript code — this allows you to customize the mapping as needed.

The benefits are obvious for using native device features like geolocation and the camera. When you build your AngularJS (Ionic or Bootstrap) app with Appery.io, you can easily take advantage of these features. You import the services to access these features via plug-ins. Just go to CREATE NEW > From Plug-in and select the service you want to use. There are tutorials available for the plug-ins, so check them out if you’re feeling lost.

Appey.io Server Code is a powerful tool that allows you to write custom server-side business logic for your app. These are the benefits you get when you use Server Code:

• Write and implement any business logic for an app. For example, you can write a script that checks inventory (Database), then sends a push notification, and then sends an e-mail using the SendGrid API
• Quickly test the script during development
• JavaScript is the language used to write the script
• Server Code is based on the popular V8 JavaScript engine. This means you can use any APIs supported by V8
• A Server Code script is instantly exposed via a REST API. This means you can quickly build a custom API

What’s a mobile conversion?

Simply put, a mobile conversion is an instance of a user taking a desired action within your mobile app. This could be completing a sale for example, or even just filling out and submitting a form. They differ from download conversions in that they are accomplished in-app, after the initial download of the app has already occurred.

Not everyone needs to worry about mobile conversions in their applications, but if you’re building an app where conversions are key, few things are more important than increasing that rate.

Mobile traffic now accounts for over 16% of all web traffic, and in general, businesses have done well in acquiring users for their apps: by 2016, there will be 2 billion smartphones in use worldwide, with an average of 27 apps per phone.

Saving a version of your app to revert back to, if necessary, before you make significant changes is a good (anxiety-reducing) practice. Appery.io provides a convenient way to make snapshots of your app. Just use the Versions feature. You only need to type in an informative note like “Changing the authentication mechanism” and then click “New Version”.  Using this, you can painlessly revert any changes you made.

In this 5-minute video you will learn how to invoke a REST API from the server (instead of directly from the client. There are a number of benefits to invoke an API from the server:

1. JavaScript is the language used to write the script (and you already know JavaScript!)
2. Additional business logic can be added around the API. For example, in addition to sending an SMS, you can also send an email (SendGrid API)
3. The API keys and tokens are secure
4. Script is exposed via REST API (to be invoked from the app)
5. Script has API to access Appery.io Database, Push
6. A script can be saved as a library and used in other scripts
7. Script changes can be made without updating the client (app)
8. It’s tool to write code 🙂
