Perform Business Logic in One API Call

In a previous article (How to Save an Object with All the Children in a Single Call to Server), we examined how to simply save an object model. However, Backendless custom services give us much more flexibility when it comes to saving objects. In this article, we are going to cover how to perform complex business logic actions such as saving an object with calculated information in one API call using custom services. As we’ll demonstrate in this example, you can actually encapsulate entire portions of your business logic on the server side.

For this example, we will build a custom service that will emulate the order process for an automotive technician service station.

Backendless Chat App with Images

In this series of articles, we are going to show you how to make a beautiful chat app that supports sending, editing, and deleting messages with both text and images.

You can download the prepared template from the author’s GitHub repo here and switch to the basicTemplate  branch. Go to the root of the downloaded project and run the `pod install`  / `pod update`  command to install all necessary dependencies. After the dependencies are installed, open the created .xcworkspace file. The basic project contains a description of ViewControllers , table cells, resources (pictures used in this app) and the keyboard appearance logic.

Using Asynchronous Callbacks with Java/Android

From time to time, we see some developers struggle with understanding the principles of asynchronous work with Backendless. In this post we’ll try to shed more light on this aspect: describe what async calls are, why you need them and how to properly perform such calls and process the results. This post will be specific to Java and Android, but most of the principles apply to any language and environment.

In this edition of Backendless Spotlight, we travel to Scandinavia to take a look at an online shopping app from Norwegian footwear company Nordås Sko. Nordås Sko wanted to make it as easy as possible for shoppers seeking professional or work shoes to find what they’re looking for, so they made an app for just that niche. The app is available only in local regions on both the Apple iTunes Store and Google Play Store.

Create Table Schema in One Query

Today, we are going to look at a useful and interesting, but hidden, feature of Backendless. Some features like these are not covered in the documentation, so they are not recommended for use in production because they are not supported and there is no guarantee that their implementation will not change. Still, these features can be very helpful during initial development. Using these features is not for the faint of heart!

Expire Objects in Data Storage

This post will show you how to implement a kind of “expiration” for your data objects. The strategy is sufficiently abstract, so it’s applicable to any resource you need to expire, including files, logs, and so on.

Since the database does not have any built-in expiration mechanism, we’ll have to implement it on our own. Fortunately, the task is pretty easy because we have access to Backendless Business Logic. The idea is to create a Timer, which is going to run with some fixed time period and delete the resources based on your criteria.

In this edition of Backendless Spotlight, we cross the Atlantic to take a closer look at TopAnimals, an educational sticker-collecting app out of Italy. With TopAnimals, users can collect animal stickers of varying rarities that offer descriptions, curiosities, and habitat information. TopAnimals is brand new to the market, launching on iTunes just last week.

In this edition of Backendless Spotlight, we travel down under to take a look at EatClub, an Australian app designed to make dining out more convenient – and less expensive. EatClub encourages you to “eat out, more often” by providing a platform for restaurants to offer last-minute deals on unfilled reservations. Unlike our previous entries which utilize Backendless Cloud, EatClub runs their backend on Backendless Pro, discusses further below. EatClub is available on iOS and Android. You can learn more about them at the EatClub website.
