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.

You will start to be able to build validations and business rules/logic and really customize the user's experience. You can essentially think of functions and expressions as ways to compare a given piece of data to another input or even itself, or perhaps manipulate it in some way.

There are a lot of functions and expressions that Mendix offers that may look similar to the ones you have seen in more traditional languages or perhaps in an application such as Microsoft Excel. Regardless, it's important to understand their intended use and syntax from within Studio Pro and how to interact with them while building out needed validation or rules in a microflow.

This section isn't intended to cover every function or expression Mendix has to offer. Rather, this is a look at...
