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.

A log message is a simple way of thinking about a piece or collection of pieces of information that indicate what is happening in your application, either through direct user interaction or system processes running behind the scenes. This contextual information is written to the application log as a "message" that is stored and can be accessed at any time either in real time or historically by downloading archived log files.

Log messages are helpful in so many different areas of your application. They are especially helpful when you're working with error handling, as we discussed in the previous section. If your application experiences an error, it's very important to write a message to the log describing what happened...
