A journey through the blog example


About the code of the blog example:

In this chapter you make a journey through a simple TYPO3 extension. While traveling on this round trip, you will get to know more about extension development with Extbase and Fluid and learn the most important stations and coordinates of extension development with the help of an example extension. You will first familiarize yourself with the geography and the typical characteristics of an extension and determine which processes are running in the background.

If you are looking for a manual specifically on creating an extension, Creating the store inventory extension will show you the right set of tools. The chapter for this journey explains the fundamentals. It could also have the title “Europe in five days.” If you discover nice places, you should revisit them later without the travel group.

You will find it beneficial to look at the source code while reading this text, so you will have an easier time getting your bearings in your own extension later.


If you use a debugger, it can be interesting to follow a full cycle in single step mode. For that, you have to set a breakpoint in the file Dispatcher.php. You will find this class in the folder for Extbase typo3/sysext/extbase/Classes/.

At the end of this chapter, you will find a short comparison of the traditional way to code an extension and an approach with Extbase and Fluid.
