Site Packages in TYPO3 v13: A Practical Guide to PAGEVIEW, Site Sets & Custom Content Elements

Creating a site package is one of the first steps in any TYPO3 project — and with TYPO3 v13, it’s easier and more structured than ever.

In this practical, beginner-friendly session, we’ll walk through building a site package using the official Sitepackage Tutorial and Sitepackage Builder. As the main author of the revised Sitepackage Tutorial for TYPO3 v13, I’ll share insights into why certain changes were made, and how you can benefit from the new structure and tools.

We’ll explore new v13 features like the PAGEVIEW TypoScript object and the improved Site Configuration (site sets), and how they simplify project setup and templating.

We’ll also look at ways to add custom content elements — either using the TYPO3 Core alone or with tools like Mask — both of which have become more accessible in TYPO3 v13.

Topics covered:

• Composer-based setup and project structure
• Registering templates, assets, and backend configuration
• Working with PAGEVIEW and site sets
• Adding custom content elements (Core and Mask)

Whether you're new to TYPO3 or just catching up with v13, this session will help you build a clean, modern site package — and understand the “why” behind each step.
