+# Deployment-Anleitung: Socket.IO mit SSL
+
+Socket.IO läuft jetzt direkt auf HTTPS-Port 3051 (nicht über Apache-Proxy).
+
+## Schritte nach dem Deployment
+
+### 1. Firewall-Port öffnen
+
+```bash
+# UFW (Ubuntu Firewall)
+sudo ufw allow 3051/tcp
+```
+
+### 2. Apache-Konfiguration aktualisieren
+
+```bash
+sudo cp /var/www/tt-tagebuch.de/apache.conf.example /etc/apache2/sites-available/tt-tagebuch.de-le-ssl.conf
+sudo systemctl restart apache2
+```
+
+### 3. systemd-Service konfigurieren (als www-data)
+
+**WICHTIG:** Der Service sollte als `www-data` laufen, nicht als `nobody`!
+
+```bash
+# Service-Datei installieren
+sudo cp /var/www/tt-tagebuch.de/tt-tagebuch.service /etc/systemd/system/
+sudo systemctl daemon-reload
+```
+
+Die Service-Datei konfiguriert:
+- User: `www-data` (Standard-Webserver-Benutzer)
+- Group: `www-data`
+- Port: 3050 (HTTP) und 3051 (HTTPS)
+
+### 4. SSL-Zertifikat-Berechtigungen setzen
+
+**WICHTIG:** Der Node.js-Prozess muss Zugriff auf die SSL-Zertifikate haben!
+
+```bash
+cd /var/www/tt-tagebuch.de/backend
+chmod +x scripts/fixCertPermissions.sh
+sudo ./scripts/fixCertPermissions.sh
+```
+
+Dieses Skript:
+- Erstellt die Gruppe `ssl-cert` (falls nicht vorhanden)
+- Fügt den Service-Benutzer (`www-data`) zur Gruppe hinzu
+- Setzt die Berechtigungen für die Zertifikate
+
+### 5. Backend neu starten
+
+**WICHTIG:** Der Backend-Server muss neu gestartet werden, damit der HTTPS-Server auf Port 3051 läuft!
+
+```bash
+# Falls als systemd-Service:
+sudo systemctl restart tt-tagebuch
+
+# Oder falls als PM2-Prozess:
+pm2 restart tt-tagebuch-backend
+```
+
+### 6. Prüfen, ob HTTPS-Server läuft
+
+```bash
+# Prüfe, ob Port 3051 geöffnet ist
+sudo netstat -tlnp | grep 3051
+# Oder:
+sudo ss -tlnp | grep 3051
+
+# Prüfe Backend-Logs
+sudo journalctl -u tt-tagebuch -f
+# Oder bei PM2:
+pm2 logs tt-tagebuch-backend
+```
+
+Du solltest folgende Meldung sehen:
+```
+🚀 HTTPS-Server für Socket.IO läuft auf Port 3051
+```
+
+### 7. Diagnose-Skript ausführen
+
+```bash
+cd /var/www/tt-tagebuch.de/backend
+node scripts/checkSocketIOServer.js
+```
+
+Dieses Skript prüft:
+- Ob SSL-Zertifikate existieren
+- Ob Port 3051 geöffnet ist
+- Ob der Server erreichbar ist
+
+### 8. Testen
+
+Im Browser sollte Socket.IO jetzt direkt zu `wss://tt-tagebuch.de:3051` verbinden.
+
+## Troubleshooting
+
+### Port 3051 ist nicht erreichbar
+
+1. **Prüfe Firewall:**
+   ```bash
+   sudo ufw status
+   sudo ufw allow 3051/tcp
+   ```
+
+2. **Prüfe, ob der Server läuft:**
+   ```bash
+   sudo netstat -tlnp | grep 3051
+   sudo ss -tlnp | grep 3051
+   ```
+
+3. **Prüfe Backend-Logs auf Fehler:**
+   ```bash
+   sudo journalctl -u tt-tagebuch -n 50
+   # Oder:
+   pm2 logs tt-tagebuch-backend --lines 50
+   ```
+
+4. **Prüfe, ob HTTPS-Server gestartet wurde:**
+   - Suche in den Logs nach: `🚀 HTTPS-Server für Socket.IO läuft auf Port 3051`
+   - Falls nicht vorhanden, prüfe auf Fehler: `⚠️  HTTPS-Server konnte nicht gestartet werden`
+
+### SSL-Zertifikat-Fehler / Berechtigungsfehler
+
+**Fehler:** `EACCES: permission denied, open '/etc/letsencrypt/live/tt-tagebuch.de/privkey.pem'`
+
+**Lösung:**
+```bash
+cd /var/www/tt-tagebuch.de/backend
+chmod +x scripts/fixCertPermissions.sh
+sudo ./scripts/fixCertPermissions.sh
+sudo systemctl restart tt-tagebuch
+```
+
+Stelle sicher, dass die Zertifikate existieren:
+```bash
+ls -la /etc/letsencrypt/live/tt-tagebuch.de/
+```
+
+Falls die Zertifikate nicht existieren:
+```bash
+sudo certbot certonly --standalone -d tt-tagebuch.de
+```
+
+### Service läuft als "nobody"
+
+**Problem:** Der Service läuft als `nobody`, was zu eingeschränkt ist.
+
+**Lösung:**
+1. Installiere die Service-Datei (siehe Schritt 3)
+2. Führe das Berechtigungs-Skript aus (siehe Schritt 4)
+3. Starte den Service neu
+
+```bash
+# Prüfe aktuellen Service-User
+sudo systemctl show -p User tt-tagebuch.service
+
+# Installiere Service-Datei
+sudo cp /var/www/tt-tagebuch.de/tt-tagebuch.service /etc/systemd/system/
+sudo systemctl daemon-reload
+sudo systemctl restart tt-tagebuch
+
+# Prüfe, ob jetzt als www-data läuft
+sudo systemctl show -p User tt-tagebuch.service
+```
+
+### Frontend verbindet nicht
+
+1. **Prüfe Browser-Konsole auf Fehler**
+2. **Prüfe, ob `import.meta.env.PROD` korrekt gesetzt ist:**
+   - In Produktion sollte die Socket.IO-URL `https://tt-tagebuch.de:3051` sein
+   - In Entwicklung sollte sie `http://localhost:3005` sein
+
+3. **Prüfe, ob die Socket.IO-URL korrekt ist:**
+   - Öffne Browser-Entwicklertools → Network
+   - Suche nach WebSocket-Verbindungen
+   - Die URL sollte `wss://tt-tagebuch.de:3051/socket.io/...` sein
+
+### Server lauscht nur auf localhost
+
+Der Server sollte auf `0.0.0.0` lauschen (nicht nur auf `localhost`). 
+Dies ist bereits in der Konfiguration eingestellt:
+```javascript
+httpsServer.listen(httpsPort, '0.0.0.0', () => {
+  console.log(`🚀 HTTPS-Server für Socket.IO läuft auf Port ${httpsPort}`);
+});
+```
+
+Falls der Server trotzdem nicht erreichbar ist, prüfe die Backend-Logs.

+# Server Node.js Upgrade-Anleitung
+
+## Problem
+
+Der Server verwendet Node.js 20.17.0, aber Vite 7.2.4 benötigt Node.js 20.19+ oder 22.12+.
+
+## Lösung 1: Node.js auf dem Server upgraden (Empfohlen)
+
+### Option A: Node.js 20.19+ installieren
+
+```bash
+# Auf dem Server:
+# Mit nvm (falls installiert):
+nvm install 20.19.0
+nvm use 20.19.0
+nvm alias default 20.19.0
+
+# Oder mit NodeSource Repository:
+curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
+sudo apt-get install -y nodejs=20.19.0-1nodesource1
+
+# Prüfe Version:
+node --version  # Sollte 20.19.0 oder höher sein
+```
+
+### Option B: Node.js 22.12+ installieren (LTS)
+
+```bash
+# Auf dem Server:
+# Mit nvm:
+nvm install 22.12.0
+nvm use 22.12.0
+nvm alias default 22.12.0
+
+# Oder mit NodeSource Repository:
+curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
+sudo apt-get install -y nodejs
+
+# Prüfe Version:
+node --version  # Sollte 22.12.0 oder höher sein
+```
+
+### Nach dem Upgrade
+
+```bash
+cd /var/www/tt-tagebuch.de/backend
+npm install  # Erstellt automatisch den Frontend-Build
+sudo systemctl restart tt-tagebuch
+```
+
+## Lösung 2: Vite auf Version 6 downgraden (Temporär)
+
+Falls Node.js nicht upgradet werden kann, wurde Vite bereits auf Version 6.0.0 downgraded.
+
+```bash
+cd /var/www/tt-tagebuch.de/backend
+npm install  # Erstellt automatisch den Frontend-Build
+sudo systemctl restart tt-tagebuch
+```
+
+**Hinweis:** Vite 6 funktioniert mit Node.js 20.17.0, aber Vite 7 bietet bessere Performance und Features.
+
+## Empfehlung
+
+**Node.js upgraden** ist die bessere Lösung, da:
+- Vite 7 bessere Performance bietet
+- Zukünftige Updates einfacher sind
+- Node.js 20.19+ oder 22.12+ LTS-Versionen sind
+

+
+1. **robots.txt**: Die Sitemap ist bereits in der `robots.txt` referenziert:
+   ```
+   Sitemap: https://tt-tagebuch.de/sitemap.xml
+   ```
+
+2. **lastmod-Datum**: Wird automatisch beim Ausführen von `update-sitemap.sh` aktualisiert
+
+3. **Nur öffentliche Seiten**: Die Sitemap enthält nur öffentlich zugängliche Seiten. Geschützte Seiten (die eine Anmeldung erfordern) sind nicht enthalten.
+
+4. **Prioritäten**: 
+   - Homepage: 1.0 (höchste Priorität)
+   - Registrierung/Login: 0.7-0.8 (wichtig für neue Nutzer)
+   - Rechtliche Seiten: 0.3 (niedrige Priorität, ändern sich selten)
+
+## Troubleshooting
+
+### Sitemap wird nicht gefunden
+- Prüfe, ob die Sitemap unter `https://tt-tagebuch.de/sitemap.xml` erreichbar ist
+- Stelle sicher, dass das Frontend gebaut wurde: `cd frontend && npm run build`
+- Prüfe die Apache-Konfiguration (sollte statische Dateien aus `/var/www/tt-tagebuch.de` servieren)
+
+### Sitemap wird nicht indexiert
+- Warte einige Stunden/Tage - Google braucht Zeit zum Crawlen
+- Prüfe in der Search Console, ob es Fehler gibt
+- Stelle sicher, dass die URLs in der Sitemap erreichbar sind
+- Prüfe, ob die `robots.txt` die Seiten nicht blockiert
+
+### Sitemap enthält Fehler
+- Validiere die XML-Struktur mit einem XML-Validator
+- Prüfe, ob alle URLs korrekt sind (keine 404-Fehler)
+- Stelle sicher, dass alle URLs HTTPS verwenden (nicht HTTP)

+# Socket.IO mit SSL direkt betreiben (Alternative zu Apache-Proxy)
+
+Falls die Apache-WebSocket-Proxy-Konfiguration nicht funktioniert, kann Socket.IO direkt mit SSL betrieben werden.
+
+## Voraussetzungen
+
+1. SSL-Zertifikat (z.B. von Let's Encrypt)
+2. Port in der Firewall öffnen (z.B. 3051)
+3. Socket.IO-Server auf HTTPS konfigurieren
+
+## Backend-Konfiguration
+
+### 1. Socket.IO auf HTTPS umstellen
+
+Ändere `backend/server.js`:
+
+```javascript
+import https from 'https';
+import fs from 'fs';
+
+// SSL-Zertifikat laden
+const httpsOptions = {
+  key: fs.readFileSync('/etc/letsencrypt/live/tt-tagebuch.de/privkey.pem'),
+  cert: fs.readFileSync('/etc/letsencrypt/live/tt-tagebuch.de/fullchain.pem')
+};
+
+// HTTPS-Server erstellen
+const httpsServer = https.createServer(httpsOptions, app);
+
+// Socket.IO initialisieren
+initializeSocketIO(httpsServer);
+
+// HTTPS-Server starten
+const httpsPort = process.env.HTTPS_PORT || 3051;
+httpsServer.listen(httpsPort, () => {
+  console.log(`🚀 HTTPS-Server läuft auf Port ${httpsPort}`);
+});
+
+// HTTP-Server für API (optional, falls API weiterhin über HTTP laufen soll)
+const httpServer = createServer(app);
+const httpPort = process.env.PORT || 3005;
+httpServer.listen(httpPort, () => {
+  console.log(`🚀 HTTP-Server läuft auf Port ${httpPort}`);
+});
+```
+
+### 2. Frontend-Konfiguration
+
+Ändere `frontend/src/services/socketService.js`:
+
+```javascript
+import { io } from 'socket.io-client';
+import { backendBaseUrl } from '../apiClient.js';
+
+let socket = null;
+
+export const connectSocket = (clubId) => {
+  // Verwende HTTPS-URL für Socket.IO
+  const socketUrl = backendBaseUrl.replace('http://', 'https://').replace(':3005', ':3051');
+  
+  if (socket && socket.connected) {
+    // Wenn bereits verbunden, verlasse den alten Club-Raum und trete dem neuen bei
+    if (socket.currentClubId) {
+      socket.emit('leave-club', socket.currentClubId);
+    }
+  } else {
+    // Neue Verbindung erstellen
+    socket = io(socketUrl, {
+      path: '/socket.io/',
+      transports: ['websocket', 'polling'],
+      reconnection: true,
+      reconnectionDelay: 1000,
+      reconnectionAttempts: 5,
+      timeout: 20000,
+      upgrade: true,
+      forceNew: false,
+      secure: true // Wichtig für HTTPS
+    });
+
+    socket.on('connect', () => {
+      console.log('Socket.IO verbunden');
+      if (socket.currentClubId) {
+        socket.emit('join-club', socket.currentClubId);
+      }
+    });
+
+    socket.on('disconnect', () => {
+      console.log('Socket.IO getrennt');
+    });
+
+    socket.on('connect_error', (error) => {
+      console.error('Socket.IO Verbindungsfehler:', error);
+    });
+  }
+
+  // Club-Raum beitreten
+  if (clubId) {
+    socket.emit('join-club', clubId);
+    socket.currentClubId = clubId;
+  }
+
+  return socket;
+};
+
+export const disconnectSocket = () => {
+  if (socket) {
+    socket.disconnect();
+    socket = null;
+  }
+};
+
+export const getSocket = () => socket;
+```
+
+### 3. Firewall-Port öffnen
+
+```bash
+# UFW (Ubuntu Firewall)
+sudo ufw allow 3051/tcp
+
+# Oder iptables
+sudo iptables -A INPUT -p tcp --dport 3051 -j ACCEPT
+```
+
+### 4. Apache-Konfiguration anpassen
+
+Entferne die Socket.IO-Proxy-Konfiguration aus Apache, da Socket.IO jetzt direkt erreichbar ist.
+
+## Vorteile
+
+- Einfacher zu konfigurieren
+- Keine Apache-Proxy-Probleme
+- Direkte WebSocket-Verbindung
+
+## Nachteile
+
+- Separater Port muss geöffnet sein
+- Zwei Ports (HTTP für API, HTTPS für Socket.IO)
+- CORS-Konfiguration muss angepasst werden
+

+# Fehlercode-System - Verwendungsanleitung
+
+## Übersicht
+
+Das Fehlercode-System ersetzt hardcodierte deutsche Fehlermeldungen durch strukturierte Fehlercodes, die im Frontend übersetzt werden.
+
+## Backend-Verwendung
+
+### 1. Fehlercode verwenden
+
+```javascript
+import HttpError from '../exceptions/HttpError.js';
+import { ERROR_CODES, createError } from '../constants/errorCodes.js';
+
+// Einfacher Fehlercode ohne Parameter
+throw new HttpError(createError(ERROR_CODES.USER_NOT_FOUND), 404);
+
+// Fehlercode mit Parametern
+throw new HttpError(
+  createError(ERROR_CODES.MEMBER_NOT_FOUND, { memberId: 123 }), 
+  404
+);
+
+// Oder direkt:
+throw new HttpError(
+  { code: ERROR_CODES.MEMBER_NOT_FOUND, params: { memberId: 123 } }, 
+  404
+);
+```
+
+### 2. Legacy-Format (wird weiterhin unterstützt)
+
+```javascript
+// Alte Variante funktioniert noch:
+throw new HttpError('Benutzer nicht gefunden', 404);
+```
+
+## Frontend-Verwendung
+
+### 1. Fehlermeldungen automatisch übersetzen
+
+Die `getSafeErrorMessage`-Funktion erkennt automatisch Fehlercodes:
+
+```javascript
+import { getSafeErrorMessage } from '../utils/errorMessages.js';
+
+// In einer Vue-Komponente (Options API)
+try {
+  await apiClient.post('/api/endpoint', data);
+} catch (error) {
+  const message = getSafeErrorMessage(error, this.$t('errors.ERROR_UNKNOWN_ERROR'), this.$t);
+  await this.showInfo(this.$t('messages.error'), message, '', 'error');
+}
+
+// In einer Vue-Komponente (Composition API)
+import { useI18n } from 'vue-i18n';
+const { t } = useI18n();
+
+try {
+  await apiClient.post('/api/endpoint', data);
+} catch (error) {
+  const message = getSafeErrorMessage(error, t('errors.ERROR_UNKNOWN_ERROR'), t);
+  await showInfo(t('messages.error'), message, '', 'error');
+}
+```
+
+### 2. Dialog-Utils mit Übersetzung
+
+```javascript
+import { buildInfoConfig, safeErrorMessage } from '../utils/dialogUtils.js';
+
+// Mit Übersetzungsfunktion
+this.infoDialog = buildInfoConfig({
+  title: this.$t('messages.error'),
+  message: safeErrorMessage(error, this.$t('errors.ERROR_UNKNOWN_ERROR'), this.$t),
+  type: 'error'
+}, this.$t);
+```
+
+## API-Response-Format
+
+### Neues Format (mit Fehlercode):
+```json
+{
+  "success": false,
+  "code": "ERROR_MEMBER_NOT_FOUND",
+  "params": {
+    "memberId": 123
+  },
+  "error": "ERROR_MEMBER_NOT_FOUND"  // Für Rückwärtskompatibilität
+}
+```
+
+### Legacy-Format (wird weiterhin unterstützt):
+```json
+{
+  "success": false,
+  "message": "Mitglied nicht gefunden",
+  "error": "Mitglied nicht gefunden"
+}
+```
+
+## Übersetzungen hinzufügen
+
+1. **Backend**: Fehlercode in `backend/constants/errorCodes.js` definieren
+2. **Frontend**: Übersetzung in `frontend/src/i18n/locales/de.json` unter `errors` hinzufügen
+
+Beispiel:
+```json
+{
+  "errors": {
+    "ERROR_MEMBER_NOT_FOUND": "Mitglied nicht gefunden.",
+    "ERROR_MEMBER_NOT_FOUND_WITH_ID": "Mitglied mit ID {memberId} nicht gefunden."
+  }
+}
+```
+
+## Migration bestehender Fehler
+
+1. Hardcodierte Fehlermeldung identifizieren
+2. Passenden Fehlercode in `errorCodes.js` finden oder erstellen
+3. Backend-Code anpassen: `throw new HttpError(createError(ERROR_CODES.XXX), status)`
+4. Übersetzung in `de.json` hinzufügen
+5. Frontend-Code muss nicht geändert werden (automatische Erkennung)

-## 0.6.39
-
- - Support for node v9
- - Support for versioning on `{libc}` to allow binaries to work on non-glic linux systems like alpine linux
-
-
-## 0.6.38
-
- - Maintaining compatibility (for v0.6.x series) with node v0.10.x
-
-## 0.6.37
-
- - Solved one part of #276: now now deduce the node ABI from the major version for node >= 2 even when not stored in the abi_crosswalk.json
- - Fixed docs to avoid mentioning the deprecated and dangerous `prepublish` in package.json (#291)
- - Add new node versions to crosswalk
- - Ported tests to use tape instead of mocha
- - Got appveyor tests passing by downgrading npm and node-gyp
-
-## 0.6.36
-
- - Removed the running of `testbinary` during install. Because this was regressed for so long, it is too dangerous to re-enable by default. Developers needing validation can call `node-pre-gyp testbinary` directory.
- - Fixed regression in v0.6.35 for electron installs (now skipping binary validation which is not yet supported for electron)
-
-## 0.6.35
-
- - No longer recommending `npm ls` in `prepublish` (#291)
- - Fixed testbinary command (#283) @szdavid92

-## 0.6.29
-
- - Add known node versions for v0.10.45, v0.12.14, v4.4.4, v5.11.1, and v6.1.0
-
-## 0.6.28
-
- - Now more verbose when remote binaries are not available. This is needed since npm is increasingly more quiet by default
-   and users need to know why builds are falling back to source compiles that might then error out.
-
-## 0.6.27
-
- - Add known node version for node v6
- - Stopped bundling dependencies
- - Documented method for module authors to avoid bundling node-pre-gyp
-   - See https://github.com/mapbox/node-pre-gyp/tree/master#configuring for details
