In this article, we’re going to review a fun feature – an ROI (return on investment) calculator. That may sound like a boring subject, but we sure tried to make it fun. Indeed, if you are a developer and are tasked with figuring out how a product or a service can save money, it may…

In another post, we described a feature where you can import data to Backendless using CSV files. In that post, we used CSV files that already had the data type defined for each column.

Now that you know how to register and login users for your application, you might be wondering what degree of control over user accounts you have with Backendless. As a developer of a Backendless-powered app, the Console is the ultimate tool where you can control all aspects of your app, including user management.

If a data table in your application has a column of the DATETIME type, the values for that column will be rendered by Backendless Console in mm/dd/yyyy hh:mm:ss format. For many applications, and specifically in some industries like telecommunications or finance, it is important to see the date objects in a “neutral” format and often…

A previous article in this series (registering app users using Backendless API) talks about how to create user accounts. If your application uses the user registration API, odds are you will need to use the Login API as well. The API is rather simple – it requires just two parameters: a value that uniquely identifies…

In another post, we wrote about Backendless File Browser – an online management system for your files and directories. One of the features built into File Browser is the ZIP Directory feature. The feature does exactly what it sounds like it would do – creating a zip file for a directory and its contents.

In another post, we described how to restrict access to all data for “guest” users. The Backendless security model lets you control access to data tables, or more generally “asset containers”, at the role and operation levels. That means an application developer can set up security restrictions for API operations on a specific data table…

There are several ways to upload file content to the server: The traditional approach where a physical file from the client environment is uploaded using the API. Creating a remote file with content generated on the client-side. In this article, we will review the first option – uploading a file with the API.

In another article, we demonstrated sample code that shows how to search for Backendless geopoints in a radius. Now we will review the API for searching for geopoints in a rectangular area. The API is very similar to the one for search in radius, except the app must define the “view port” or the rectangular…
