Package Exports

@startnext/chrome
@startnext/chrome/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@startnext/chrome) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Architecture

Jede Component ist modular in drei Dateien aufgeteilt:

src/
├── components/
│   ├── base/
│   │   ├── BaseComponent.ts    # Abstrakte Basis (Shadow DOM, Events, Theming)
│   │   ├── icons.ts            # SVG-Icon-Registry
│   │   └── styles.ts           # Shared Reset-CSS
│   ├── header/
│   │   ├── StartnextHeader.ts  # Logik (Scroll, Drawers, Lottie, Events)
│   │   ├── header.css.ts       # CSS als Template-Literal-Export
│   │   └── header.template.ts  # Render-Funktionen (HTML-Strings)
│   └── footer/
│       ├── StartnextFooter.ts  # Logik (Render, Events)
│       ├── footer.css.ts       # CSS als Template-Literal-Export
│       └── footer.template.ts  # Render-Funktion (HTML-String)
├── data/
│   └── mockData.ts             # Mock-Daten
├── types/
│   └── index.ts                # Alle TypeScript-Interfaces
└── index.ts                    # Barrel-Export

Konventionen:

CSS in *.css.ts als exportierter Template-Literal-String (kein extra Build-Plugin nötig)
Templates in *.template.ts als reine Funktionen die HTML-Strings zurückgeben
Logik in der Hauptdatei: Event-Handling, State, Lifecycle
BEM-Naming für CSS-Klassen (headbar__left, drawer__item--highlighted)
Shadow DOM (open mode), kein Virtual DOM
