Overview

The project delivers a production-ready weather widget with automated data ingestion, structured caching, and flexible frontend rendering via TYPO3 Content Blocks.

It is implemented as a standalone TYPO3 extension (not a site package), designed for long-term maintainability and real-world API conditions.

Backend Architecture & Data Processing

Designed and implemented a scheduler-based data ingestion pipeline using TYPO3 Scheduler and CLI commands.
Integrated official MeteoSwiss NOWCAST and FORECAST APIs, supporting hourly, multi-hour, and daily datasets.
Built robust parsing and normalization logic to handle inconsistent timestamps, partial data, and historical overlaps.
Implemented a file-based caching strategy optimized for frontend performance and stability.

TYPO3 Extension & Content Block Design

Implemented as a clean TYPO3 extension, fully compatible with TYPO3 13 LTS.
Frontend integration is based on TYPO3 Content Blocks, enabling editors to configure weather stations and display modes without code changes.
Strict separation of concerns between data processing, configuration, and presentation layers.

Frontend Integration

Fluid-based frontend rendering using pre-generated JSON files.
No direct API calls from the browser, ensuring predictable performance and cache-friendly behavior.
Responsive layouts, dynamic weather symbols, and clean asset handling.

Reliability & Performance

Scheduler tasks are idempotent and safe for repeated execution.
Partial failures do not corrupt existing data or frontend output.
Time-series data is stored on the filesystem to avoid database bloat.

Technology Stack

CMS: TYPO3 13.4 (LTS)
Backend: PHP 8.2+, TYPO3 Scheduler, CLI
Frontend: Fluid Templates, Vanilla JS, CSS
Data: MeteoSwiss official APIs, JSON processing
Architecture: Extension + Content Blocks

Why This Project Matters

This project demonstrates the ability to design robust data pipelines, work with real-world API inconsistencies, and build maintainable TYPO3 solutions with a clear separation between backend logic and frontend rendering.
