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.

Chapter 9: Customizing Your App

In this chapter, we will dive deeper beyond opening pages and saving records. We will take a closer look at adding custom business logic and rules to drive user experience and functionality. We will turn your user stories into working, navigable applications that take your development to the next level!

To help get us there, we will cover the following topics and concepts:

  • Functions and expressions – We will discuss functions that will help us work with and manipulate string attributes, integers, enumerations, and DateTime attributes. We will also explore relational expressions that are used to work with multiple data points at the same time, for example, finding the delta between two integers.
  • Sub-microflows – You may know what a microflow is, but what is a sub-microflow? In the previous chapter, we extracted a set of activities in a microflow to create a sub-microflow. But why was that necessary? In this chapter, we will...
