Creating a new Extension¶
This chapter is not a tutorial about how to create an Extension. It only aims to be a list of steps to perform and key information to remember.
First you have to register an extension key. This is the unique identifier for your extension.
Kickstarting the Extension¶
Although it is possible to write every single line of an extension from scratch, there is a tool which makes it easier to start. It is called "Extension builder" (key: "extension_builder") and can be installed from TER.
The extension builder in TER is usually not up to date. If you can't find a version supporting the latest TYPO3 version in TER, you can take a look into the official github repository.
The Extension Builder comes with its own BE module:
Note that this tool is not a complete editor. It helps you creating the scaffolding of your extension, generating the necessary files. It's then up to you to fill these with the relevant code.
The Extension Builder has some possibility to preserve code, but it should still be used with care.
After the extension is written to your computer's disk you will be able to install it locally and start using it.
Please refer to the Extension Builder's manual for more information.
