What is an extension? (XDG)
<< Back to Extension manuals page
An extension is basicly a piece of software that adds or alters the functionality of TYPO3. The concept of extensions makes TYPO3 to one of the most flexible CMS-Frameworks around for you can achive virtually every function you need TYPO3 to take care of.
A wide variety of extensions can be downloaded from the TYPO3 extension repository, but being interested in a "Extension Developers Guide" I assume that you already have been there and downloaded some of the extensions to play around with.
Make shure you installed the following extensions for they are great helpers when developing your own code:
- extdeveval Extension Development Evaluator
- sg_showdoku Show Typo3 Info
- kickstarter
Also the following Tutorials and Videos are a great help for first steps:
- Backend Programming
- Basic Extension Tutorial: Creating a basic extension
I encourage you to follow the tutorial "Backend Programming" step by step, even if you will later create all the basic files with the Kickstarter. The reason is, that you get a feeling for what the different files and entries are for, escpecially when making mistakes that lead to misbehavior of TYPO3. It's good to start from scratch once, although you'll be happy that most of the things can be achieved by using the kickstarter later on.
This should keep you busy for a while.
