TYPO3 Frontend Patterns

Reusable implementation patterns for TYPO3 v13 and v14.3 LTS sitepackage development. Each pattern provides a complete implementation with Fluid template, TypeScript plugin, SCSS partial, and accessibility considerations.

v14 heads-up: the core no longer concatenates or compresses frontend CSS/JS (Breaking #108055). Pair these patterns with an external build tool — see typo3-vite-skill. Fluid 5 (v14) enforces strict ViewHelper typing (#108148): all VHs in pattern templates must have typed arguments + render(): string. Camino (v14.1+, #108539) is the v14 core's default theme alternative to bootstrap-package — patterns stay theme-agnostic.

These patterns solve common frontend problems that every TYPO3 sitepackage encounters. Instead of building from scratch, use these proven implementations that handle edge cases (scroll performance, reduced-motion, keyboard navigation, ARIA live regions) correctly from the start.

Available Patterns

Pattern Description Key Features
Sticky Header Scroll-triggered fixed header IntersectionObserver, CSS transitions
Lazy Loading Deferred component initialization IntersectionObserver, placeholder content
Breadcrumb Breadcrumb navigation JSON-LD structured data, Schema.org
Language Switcher Multi-language navigation b13/menus LanguageMenu, flag icons
Animations Scroll-triggered animations prefers-reduced-motion support
Scroll to Anchor Smooth scroll with offset Header height compensation
Skeleton Loading CSS placeholder animations Content layout stability
Toast Notification Notification messages Auto-dismiss, ARIA live region
Back to Top Scroll-to-top button Visibility threshold, smooth scroll

Implementation Convention

Each pattern follows the same structure:

  1. Fluid template -- Markup with semantic HTML and ARIA attributes
  2. TypeScript plugin -- Behavior with DOMContentLoaded initialization
  3. SCSS partial -- Styling with Bootstrap integration
  4. Vite entrypoint -- Code splitting via *.entry.ts
