Summary

Now you should have some idea about the differences between a plugin, a module and a component. We discussed what Joomla! version you should support in your development (which is definitely Joomla! 3, and possibly Joomla! 2.5 while it remains the current long term release). We touched on some of the new features of Joomla! 3 such as Bootstrap and jQuery. We talked about why you should use the GNU GPL for your license, and the associated benefit of a JED listing. We discussed some of the common business models used by Joomla! extension developers and then talked about the tools that you will need to use to develop Joomla! extensions. We briefly looked at the coding standards, and then talked about MVC and why we should use the Legacy classes. We talked about upgrading existing Joomla! 2.5 extensions to Joomla! 3, and we also talked about forking. Now get ready for the next chapter where we will start to get our hands dirty with some coding that you can follow along with to create your first Joomla! extension.
