TYPO3 Rector Upgrade Patterns
Compatibility: TYPO3 v14.x This skill covers patterns for writing code that works on TYPO3 v14.
TYPO3 API First: Always use TYPO3's built-in APIs, core features, and established conventions before creating custom implementations. Do not reinvent what TYPO3 already provides. Always verify that the APIs and methods you use exist and are not deprecated in TYPO3 v14 by checking the official TYPO3 documentation.
1. Introduction to TYPO3 Rector
Rector is an automated refactoring tool that helps migrate TYPO3 PHP code between major versions. It applies predefined rules to update deprecated code patterns. For non-PHP migrations (FlexForms, TypoScript, Fluid, YAML), use Fractor -- see the typo3-fractor skill.
