Building Low-Code Applications with Mendix

By: Bryan Kenneweg, Imran Kasam, Micah McMullen

Overview of this book

Low-code is a visual approach to application development. It enables developers of varying experience levels to create web and mobile apps using drag-and-drop components and model-driven logic through a graphic user interface. Mendix is among the fastest-growing platforms that enable low-code enthusiasts to put their software ideas into practice without having to write much code, and Building Low-Code Applications with Mendix will help you get up and running with the process using examples and practice projects. The book starts with an introduction to Mendix, along with the reasons for using this platform and its tools for creating your first app. As you progress, you’ll explore Mendix Studio Pro, the visual environment that will help you learn Mendix app creation. Once you have your working app ready, you’ll understand how to enhance it with custom business logic and rules. Next, you’ll find out how to defend your app against bad data, troubleshoot and debug it, and finally, connect it with real-world business platforms. You’ll build practical skills as the book is filled with examples, real-world scenarios, and explanations of the tools needed to help you build low-code apps successfully. By the end of this book, you’ll have understood the concept of low-code development, learned how to use Mendix effectively, and developed a working app.

Stepping through it – the Debugger

The Debugger is an essential tool in any Mendix developer's tool box. This will become your best friend when you are in development mode and inevitably tracking down those elusive bugs that will no doubt find their way into your application.

If your Debugger window is not already visible among the other windows in Studio Pro, be sure to add it! To do so, click View | Debug Windows | Debugger, as shown in the following screenshot:

The debugger is incredibly helpful during the development phase if you are trying to determine if a new piece of functionality works as intended. To begin using the Debugger, simply add a breakpoint anywhere in the microflow you wish to take a closer look at.

Right-click on any action and select Add breakpoint. You will know a breakpoint has been added to the microflow because you will see a red circle in the bottom-right corner of...
