|
||||
|
||||
### Integration mit Common-UI
|
||||
|
||||
Die Web-App nutzt die geteilte MVVM-Architektur von common-ui:
|
||||
|
||||
```kotlin
|
||||
fun main() {
|
||||
onWasmReady {
|
||||
try {
|
||||
renderComposable(rootElementId = "root") {
|
||||
// Erweiterte Fehlerbehandlung und ordnungsgemäße Entsorgung
|
||||
DisposableEffect(Unit) {
|
||||
onDispose {
|
||||
console.log("Disposing web app components")
|
||||
}
|
||||
}
|
||||
|
||||
// Verwendet geteilte MVVM App-Komponente
|
||||
MeldestelleWebApp()
|
||||
}
|
||||
} catch (e: Exception) {
|
||||
showFallbackErrorUI("Application failed to start: ${e.message}")
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Build-Konfiguration
|
||||
|
||||
### Erweiterte Webpack-Einrichtung
|
||||
|
||||
Die web-app verwendet optimierte Webpack-Konfiguration für moderne Web-Entwicklung:
|
||||
|
||||
#### JavaScript Ziel-Konfiguration
|
||||
```kotlin
|
||||
js(IR) {
|
||||
binaries.executable()
|
||||
browser {
|
||||
commonWebpackConfig {
|
||||
cssSupport {
|
||||
enabled.set(true)
|
||||
}
|
||||
// Source Maps für Debugging aktivieren
|
||||
devtool = "source-map"
|
||||
}
|
||||
// Webpack für Produktionsoptimierung konfigurieren
|
||||
webpackTask {
|
||||
mainOutputFileName = "web-app.js"
|
||||
}
|
||||
// Entwicklungsserver konfigurieren
|
||||
runTask {
|
||||
mainOutputFileName = "web-app.js"
|
||||
sourceMaps = true
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Abhängigkeiten
|
||||
```kotlin
|
||||
val jsMain by getting {
|
||||
dependencies {
|
||||
implementation(project(":client:common-ui"))
|
||||
implementation(compose.html.core)
|
||||
implementation(compose.runtime)
|
||||
implementation(libs.ktor.client.js)
|
||||
implementation(libs.kotlinx.coroutines.core)
|
||||
// Erweiterte Web-spezifische Abhängigkeiten
|
||||
implementation(libs.ktor.client.contentNegotiation)
|
||||
implementation(libs.ktor.client.serialization.kotlinx.json)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Test-Konfiguration
|
||||
```kotlin
|
||||
val jsTest by getting {
|
||||
dependencies {
|
||||
implementation(libs.kotlin.test)
|
||||
implementation(libs.kotlinx.coroutines.test)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Webpack-Optimierungen
|
||||
```kotlin
|
||||
// Web-spezifische Optimierungen
|
||||
tasks.named("jsBrowserDevelopmentWebpack") {
|
||||
outputs.upToDateWhen { false }
|
||||
}
|
||||
|
||||
tasks.named("jsBrowserProductionWebpack") {
|
||||
outputs.upToDateWhen { false }
|
||||
}
|
||||
```
|
||||

|
||||
|
||||
## Progressive Web App Features
|
||||
|
||||
### PWA-Manifest
|
||||
|
||||
Die Web-App beinhaltet ein umfassendes PWA-Manifest (`manifest.json`):
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "Meldestelle Web Application",
|
||||
"short_name": "Meldestelle",
|
||||
"description": "Professional web application for the Meldestelle system",
|
||||
"start_url": "/",
|
||||
"display": "standalone",
|
||||
"background_color": "#ffffff",
|
||||
"theme_color": "#1976d2",
|
||||
"lang": "de",
|
||||
"scope": "/",
|
||||
"categories": ["business", "productivity"],
|
||||
"icons": [
|
||||
{
|
||||
"src": "/icons/icon-192x192.png",
|
||||
"sizes": "192x192",
|
||||
"type": "image/png",
|
||||
"purpose": "any maskable"
|
||||
},
|
||||
{
|
||||
"src": "/icons/icon-512x512.png",
|
||||
"sizes": "512x512",
|
||||
"type": "image/png",
|
||||
"purpose": "any maskable"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Moderne HTML-Vorlage
|
||||
|
||||
Erweiterte `index.html` mit modernen Web-Standards:
|
||||
|
||||
- **Sicherheits-Header**: CSP, XSS-Schutz, Frame-Optionen
|
||||
- **SEO-Optimierung**: Meta-Tags, Schlüsselwörter, Beschreibungen
|
||||
- **Leistung**: Preconnect, DNS-Prefetch, Ressourcen-Hints
|
||||
- **PWA-Unterstützung**: Manifest-Link, Theme-Farben, Viewport-Einstellungen
|
||||

|
||||
|
||||
## Entwicklung
|
||||
|
||||
### Voraussetzungen
|
||||
|
||||
| Tool | Version | Zweck |
|
||||
|------|---------|-------|
|
||||
| JDK | 21 (Temurin) | Kotlin/JS-Kompilierung und Gradle-Build |
|
||||
| Node.js | ≥ 20 | JavaScript-Laufzeit und Package-Management |
|
||||
| Gradle | 8.x (wrapper) | Build-Automatisierung |
|
||||
|
||||
### Die Anwendung erstellen
|
||||
|
||||
```bash
|
||||
# Die Web-Anwendung kompilieren
|
||||
./gradlew :client:web-app:compileKotlinJs
|
||||
|
||||
# Entwicklungsserver mit Hot Reload starten
|
||||
./gradlew :client:web-app:jsBrowserDevelopmentRun
|
||||
|
||||
# Produktions-Bundle erstellen
|
||||
./gradlew :client:web-app:jsBrowserProductionWebpack
|
||||
```
|
||||
|
||||
### Entwicklungsserver
|
||||
|
||||
Der Entwicklungsserver bietet:
|
||||
- **Hot Reload**: Automatisches Neuladen bei Code-Änderungen
|
||||
- **Source Maps**: Vollständige Debugging-Unterstützung
|
||||
- **CORS-Unterstützung**: Ordnungsgemäße API-Integration
|
||||
- **Lokale Entwicklung**: Läuft typischerweise auf `http://localhost:8080`
|
||||
|
||||
### Tests ausführen
|
||||
|
||||
```bash
|
||||
# Alle JavaScript-Tests ausführen
|
||||
./gradlew :client:web-app:jsTest
|
||||
|
||||
# Spezifischen Test ausführen
|
||||
./gradlew :client:web-app:jsTest --tests "MainTest"
|
||||
|
||||
# Ausführliche Test-Ausgabe
|
||||
./gradlew :client:web-app:jsTest --info
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Tests
|
||||
|
||||
### Testabdeckung
|
||||
|
||||
| Komponente | Test-Datei | Tests | Abdeckung |
|
||||
|-----------|-----------|-------|----------|
|
||||
| Hauptanwendung | MainTest.kt | 4 | Bootstrap, Struktur, Styling |
|
||||
|
||||
### JavaScript-kompatible Tests
|
||||
|
||||
```kotlin
|
||||
class MainTest {
|
||||
@Test
|
||||
fun `main function should be accessible`()
|
||||
|
||||
@Test
|
||||
fun `package structure should be correct`()
|
||||
|
||||
@Test
|
||||
fun `AppStylesheet should be accessible`()
|
||||
|
||||
@Test
|
||||
fun `web app structure should be well organized`()
|
||||
}
|
||||
```
|
||||
|
||||
### Test-Überlegungen für Kotlin/JS
|
||||
|
||||
- **Keine Reflection**: Tests vermeiden Java Reflection APIs
|
||||
- **Browser-Umgebung**: Tests laufen in JavaScript-Umgebung
|
||||
- **Begrenzte APIs**: Einige JVM-spezifische Test-Utilities nicht verfügbar
|
||||

|
||||
|
||||
```kotlin
|
||||
object AppStylesheet : StyleSheet() {
|
||||
val container by style {
|
||||
// Container-Styles
|
||||
}
|
||||
|
||||
val header by style {
|
||||
// Header-Styles
|
||||
}
|
||||
|
||||
val main by style {
|
||||
// Hauptinhalt-Styles
|
||||
}
|
||||
|
||||
val footer by style {
|
||||
// Footer-Styles
|
||||
}
|
||||
|
||||
val card by style {
|
||||
// Card-Komponenten-Styles
|
||||
}
|
||||
|
||||
val button by style {
|
||||
// Button-Styles
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
