Dyjit’s vision is to make life better by introducing digital experiences where they do not yet exist. Dyjit’s first product, knowye (know what you eat), is a hospitality platform that transforms the traditional paper menu into a digital marketing channel and enables restaurants to cater and market to shifting consumer needs.

  • Filter the menu to items that meet your preferences. For example, if you are a vegan or looking for a gluten-free dish, your personal menu with additional ingredient related details will be shown.
  • Select items for your order.
  • Estimate your bill, calculate the tip, split with your group.
  • Add items to your wishlist or favorites.
  • Keep your menu and selection history.

The Dyjit team selected the Appery.io lowcode platform to build and launch their first mobile app.

The Appery.io visual App Builder allows building the app UI 3-4 times faster than using traditional tools.

The Appery.io platform also provides out-of-the-box, integrated backend services such as a cloud database, Server Code for app logic and Push Notifications. This means you don’t need to look for any other backend services and can build and test the entire app quickly and with less resources. The platform enables building a complete mobile app fast, without needing to have a traditional development team.

The app UI was quickly built using the Appery.io App Builder for jQuery Mobile. On the backend, the app leverages the Appery.io Database and Server Code for custom app logic. Running the app on the Appery.io platform will enable the Dyjit team to easily scale the app to any number of backend API calls without lifting a finger. And that’s precisely the reason why the Dyjit team selected the Appery.io platform – it enables them to spend time building their product without worrying about app infrastructure and tooling.

Knowye is available in the Apple and Android app stores and piloting at Heartland Brewery in New York’s Port Authority. Follow knowye’s progress on their Facebook page.

Bon appetite!

Exposing a SQL Database via REST APIs: a How-To Video Guide for Developers

Posted: February 21st, 2017Author:



Many organizations that are building mobile apps need to connect to and reuse existing (internal) systems. One of the most common system is a relational (SQL) database.

We have prepared two short videos that will show you how to do that using Appery.io API Express.

API Express connects to a relational database and exposes the database tables via REST APIs. Once the APIs are created, the mobile app can easily consume the APIs.

There are two approaches exposing a database:

The first approach automatically generates CRUD-like APIs to work with a database table. In many apps, this is close to 80% of what an app might need. This automatic approach also comes with very sophisticated offline support. In other words, you app can work offline and sync data with a remote database when a connection is reestablished.

With the second approach, you get full control as you write the actual SQL query (or Stored Procedure) that will be executed. With this approach, you can use a visual service editor to orchestrate the REST API. In addition to the SQL component (connector), you can use connectors such as Web Service (WSDL), REST  and others.

It is safe to assume that you have experience this before. You go into a conference room to have an important phone call or meeting and someone is already sitting there. Someone is sitting there because your organization doesn’t have a conference room reservation software or even it it does have one, it’s so cumbersome to use, no one uses it.

At Exadel, the parent company behind Appery.io, with over 800 employees and 7 worldwide offices – this was happening on daily basis. When you come to a conference room to have an important meeting and can’t use it, it causes confusion (if someone is already inside the room) you waste time and other resources.

To solve this mandate problem, Exadel decided to build a mobile conference management app using the Appery.io platform and deploy it throughout its office worldwide.

Appery.io, Conference Room Booking App, SOAP, RESTful API,  Appery.io App Builder, Google Calendar

The app is called Conference Room Booking App.

The app communicates with your Google Calendar via SOAP services and retrieves details about ongoing and upcoming events. In order to connect to an external SOAP service and expose it via RESTful APIs, the app uses Appery.io API Express.

The app uses the Appery.io cloud database to store meeting information and conference room information and bookings.

The app UI was built using Appery.io App Builder for Ionic.

The complete app was designed, developed and tested in about 16 hours.

Scalability and Resilience: Learn How Appery.io Ensures API Express and Server Code On-demand Deployment

Posted: February 7th, 2017Author:

Appery.io had a strong 2016 and inches closer and closer to 400,000 developers. At the same time, the constant platform updates we roll out add more benefits, services, features, and options. Even without the constant updates, supporting a platform with so many developers would not be a simple task. Our platform has to be ready for continuous updates, increased load, and new user requests and requirements.

We want to provide high SLA level services and avoid unexpected slowdowns and downtimes for customers’ apps even during peak hours. To provide the required scalability and resilience, we rely on industry leader Amazon Web Services and its various features such as Auto Scaling, Launch Configurations, and CloudWatch.

In this blog post you will learn how exactly we ensure scalability and resilience for Appery.io API Express and Server Code services.

Ringing in 2017 With a Big Platform Update: iOS 10, Cordova Update, Automatic APIs Sync and More

Posted: January 29th, 2017Author:

We are happy to share that we starting 2017 with a big platform update. Read this blog post to learn what’s new.

iOS 10 Support

This update brings full iOS 10 support. This means when you build a binary app for iOS, it should run on an iOS device running version 10 without any problems.


This support is possible with Apache Cordova library update.

Apache Cordova Upgrade

In order to provide full iOS 10 support, we have upgraded the Apache Cordova library. The latest Cordova library for iOS is version 4.3.0 and for Android is 5.2.2. This update brings many bug fixes, improvements to Cordova. Your hybrid app will be just a little bit better and that’s good. Please read the technical release notes about this update.

The Appery.io Tester app will also be updated with the new Cordova library. Read more about it here.

Automatically Sync Backend Services Changes with the App Builder

Integration between the App Builder and Backend Services is one of the core values in the Appery.io platform. Importing API services into an app is very simple:


Now, if you made any changes to the backend APIs, you had to either manually update the service in the App Builder or delete the service and then import it again. These approaches are not very good so with this update we are introducing an automatic sync feature between the App Builder and Backend Services. When you update a backend API service, simply click the Check for update button to update the service in the App Builder.


This is very nice as you no longer need to make manual changes or even delete the services. Right now this feature is available only in an Ionic app but we are planning to add this support to a jQuery Mobile app as well.

Appery.io Platform Now Supports the IPv6 Network Protocol

Posted: January 25th, 2017Author:



We are happy to share that the Appery.io platform now has support for the IPv6 protocol. In case you don’t know what IPv6 is, you can read more about it here. IPv6 is is the most recent version of the Internet Protocol (IP) and Apple requires all apps to support this network protocol. This means that an app published to the App Store has to use IPv6 network protocol to communicate with the app backend. That’s why this support is important. Our goal has always been to support all the latest and modern features, technologies and requirements on the Appery.io platform.

Now you get all the benefits of using IPv6 network with Appery.io Backend Services:

  • API Express
  • Server Code
  • Database
  • Auto-update

The above services now all support IPv6, you can still use the old IPv4 version as well.


IPv6 support information

You can also check out IPv6 validation for api.appery.io.

IPv6 support is important as it allows to submit apps to the Apple App Store. This is just the first phase where IPv6 is supported for communication between app and backend services. The second phase will include IPv6 support to external services from Appery.io Backend Services such as API Express or Server Code.

How to Search the Database by Date From Server-side JavaScript

Posted: January 19th, 2017Author:


Searching or querying a database is one of the most common actions in a mobile app. Appery.io platform provides a cloud database to store any app data and Server Code that allows to write any server-side app logic using JavaScript. Server Code has an API to query the database that makes it easy to perform search queries based on a date. In this blog post you will learn how to write a script to query a database collection using dates.

To start, we need to create a sample database collection. Our collection looks like this:

Database collection

Database collection

The collection has two built-in date columns:

  • _createdAt – the time when a record was created
  • _updatedAt – the time when a record was updated (default value is set to _createdAt)

and two custom columns, both are of Date type:

  • startTime
  • endTime

You can of course include any other data.

Now let’s get to the code.

The first code examples shows how to query by using the built-in fields (_createdAt or _updatedAt).

This search query will return all objects where the _updatedAt date is less then ($lt) the current time (when the script runs).

When using one of the built-in data types in a query (_createdAt, _updatedAt), the date value must be formatted in ISO format. When using a custom column with Date type, using ISO format is not required.

The next code examples uses a custom endDate column (type Date). Note that the syntax to use the built-in date column (above) and a custom column is slightly different:

This query returns all records where the endTime is less than December 31, 2016. Based on data in the collection, only the record that contains tablets will be returned. This is how the response looks:

Let’s now look at another code example where we will use the startTime and endTime together.

In the following code snippet we query for all objects where the startTime is greater than December 31, 2016 and the endTime is less then February 1, 2017.

Querying the database by dates or any other columns is best suited for server-side logic as you can test the script and ensure it works before using in an app. Moving this logic to the client would only complicate the app and make it more error prone.

Once the Server Code script is tested and read you can import the service API for it inside the App Builder. This short video shows how to import a backend service. To learn more about Server Code, watch the Server Code YouTube playlist videos.
