# BizMatch SSR - Schritt-für-Schritt-Anleitung
|
||||
|
||||
## Problem: SSR startet nicht auf neuem Laptop?
|
||||
|
||||
Diese Anleitung hilft Ihnen, BizMatch mit Server-Side Rendering (SSR) auf einem neuen Rechner zum Laufen zu bringen.
|
||||
|
||||
---
|
||||
|
||||
## Voraussetzungen prüfen
|
||||
|
||||
```bash
|
||||
# Node.js Version prüfen (mind. v18 erforderlich)
|
||||
node --version
|
||||
|
||||
# npm Version prüfen
|
||||
npm --version
|
||||
|
||||
# Falls Node.js fehlt oder veraltet ist:
|
||||
# https://nodejs.org/ → LTS Version herunterladen
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Schritt 1: Repository klonen (falls noch nicht geschehen)
|
||||
|
||||
```bash
|
||||
git clone https://gitea.bizmatch.net/aknuth/bizmatch-project.git
|
||||
cd bizmatch-project/bizmatch
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Schritt 2: Dependencies installieren
|
||||
|
||||
**WICHTIG:** Dieser Schritt ist essentiell und wird oft vergessen!
|
||||
|
||||
```bash
|
||||
cd ~/bizmatch-project/bizmatch
|
||||
npm install
|
||||
```
|
||||
|
||||
> **Tipp:** Bei Problemen versuchen Sie: `rm -rf node_modules package-lock.json && npm install`
|
||||
|
||||
---
|
||||
|
||||
## ⚠️ WICHTIG: Erstes Setup auf neuem Laptop
|
||||
|
||||
**Wenn Sie das Projekt zum ersten Mal auf einem neuen Rechner klonen, müssen Sie ZUERST einen Build erstellen!**
|
||||
|
||||
```bash
|
||||
cd ~/bizmatch-project/bizmatch
|
||||
|
||||
# 1. Dependencies installieren
|
||||
npm install
|
||||
|
||||
# 2. Build erstellen (erstellt dist/bizmatch/server/index.server.html)
|
||||
npm run build:ssr
|
||||
```
|
||||
|
||||
**Warum?**
|
||||
- Die `dist/` Folder werden NICHT ins Git eingecheckt (`.gitignore`)
|
||||
- Die Datei `dist/bizmatch/server/index.server.html` fehlt nach `git clone`
|
||||
- Ohne Build → `npm run serve:ssr` crasht mit "Cannot find index.server.html"
|
||||
|
||||
**Nach dem ersten Build** können Sie dann Development-Befehle nutzen.
|
||||
|
||||
---
|
||||
|
||||
## Schritt 3: Umgebung wählen
|
||||
|
||||
### Option A: Entwicklung (OHNE SSR)
|
||||
|
||||
Schnellster Weg für lokale Entwicklung:
|
||||
|
||||
```bash
|
||||
npm start
|
||||
```
|
||||
|
||||
- Öffnet automatisch: http://localhost:4200
|
||||
- Hot-Reload aktiv (Code-Änderungen werden sofort sichtbar)
|
||||
- **Kein SSR** (schneller für Entwicklung)
|
||||
|
||||
### Option B: Development mit SSR
|
||||
|
||||
Für SSR-Testing während der Entwicklung:
|
||||
|
||||
```bash
|
||||
npm run dev:ssr
|
||||
```
|
||||
|
||||
- Öffnet: http://localhost:4200
|
||||
- Hot-Reload aktiv
|
||||
- **SSR aktiv** (simuliert Production)
|
||||
- Nutzt DOM-Polyfills via `ssr-dom-preload.mjs`
|
||||
|
||||
### Option C: Production Build mit SSR
|
||||
|
||||
Für finalen Production-Test:
|
||||
|
||||
```bash
|
||||
# 1. Build erstellen
|
||||
npm run build:ssr
|
||||
|
||||
# 2. Server starten
|
||||
npm run serve:ssr
|
||||
```
|
||||
|
||||
- Server läuft auf: http://localhost:4200
|
||||
- **Vollständiges SSR** (wie in Production)
|
||||
- Kein Hot-Reload (für Änderungen erneut builden)
|
||||
|
||||
---
|
||||
|
||||
## Schritt 4: Testen
|
||||
|
||||
Öffnen Sie http://localhost:4200 im Browser.
|
||||
|
||||
### SSR funktioniert, wenn:
|
||||
|
||||
1. **Seitenquelltext ansehen** (Rechtsklick → "Seitenquelltext anzeigen"):
|
||||
- HTML-Inhalt ist bereits vorhanden (nicht nur `<app-root></app-root>`)
|
||||
- Meta-Tags sind sichtbar
|
||||
|
||||
2. **JavaScript deaktivieren** (Chrome DevTools → Settings → Disable JavaScript):
|
||||
- Seite zeigt Inhalt an (wenn auch nicht interaktiv)
|
||||
|
||||
3. **Network-Tab** (Chrome DevTools → Network → Doc):
|
||||
- HTML-Response enthält bereits gerenderten Content
|
||||
|
||||

|
||||
|
||||
## Häufige Probleme und Lösungen
|
||||
|
||||
### Problem 1: `npm: command not found`
|
||||
|
||||
**Lösung:** Node.js installieren
|
||||
|
||||
```bash
|
||||
# Ubuntu/Debian
|
||||
curl -fsSL https://deb.nodesource.com/setup_lts.x | sudo -E bash -
|
||||
sudo apt-get install -y nodejs
|
||||
|
||||
# macOS
|
||||
brew install node
|
||||
|
||||
# Windows
|
||||
# https://nodejs.org/ → Installer herunterladen
|
||||
```
|
||||
|
||||
### Problem 2: `Cannot find module '@angular/ssr'`
|
||||
|
||||
**Lösung:** Dependencies neu installieren
|
||||
|
||||
```bash
|
||||
rm -rf node_modules package-lock.json
|
||||
npm install
|
||||
```
|
||||
|
||||
### Problem 3: `Error: EADDRINUSE: address already in use :::4200`
|
||||
|
||||
**Lösung:** Port ist bereits belegt
|
||||
|
||||
```bash
|
||||
# Prozess finden und beenden
|
||||
lsof -i :4200
|
||||
kill -9 <PID>
|
||||
|
||||
# Oder anderen Port nutzen
|
||||
PORT=4300 npm run serve:ssr
|
||||
```
|
||||
|
||||
### Problem 4: `Error loading @angular/platform-server` oder "Cannot find index.server.html"
|
||||
|
||||
**Lösung:** Build fehlt oder ist veraltet
|
||||
|
||||
```bash
|
||||
# dist-Ordner löschen und neu builden
|
||||
rm -rf dist
|
||||
npm run build:ssr
|
||||
|
||||
# Dann starten
|
||||
npm run serve:ssr
|
||||
```
|
||||
|
||||
**Häufiger Fehler auf neuem Laptop:**
|
||||
- Nach `git pull` fehlt der `dist/` Ordner komplett
|
||||
- `index.server.html` wird beim Build erstellt, nicht ins Git eingecheckt
|
||||
- **Lösung:** Immer erst `npm run build:ssr` ausführen!
|
||||
|
||||
### Problem 5: "Seite lädt nicht" oder "White Screen"
|
||||
|
||||
**Lösung:**
|
||||
|
||||
1. Browser-Cache leeren (Strg+Shift+R / Cmd+Shift+R)
|
||||
2. DevTools öffnen → Console-Tab → Fehler prüfen
|
||||
3. Sicherstellen, dass Backend läuft (falls API-Calls)
|
||||
|
||||
### Problem 6: "Module not found: Error: Can't resolve 'window'"
|
||||
|
||||
**Lösung:** Browser-spezifischer Code wird im SSR-Build verwendet
|
||||
|
||||
- Prüfen Sie `ssr-dom-polyfill.ts` - DOM-Mocks sollten vorhanden sein
|
||||
- Code mit `isPlatformBrowser()` schützen:
|
||||
|
||||
```typescript
|
||||
import { isPlatformBrowser } from '@angular/common';
|
||||
import { PLATFORM_ID } from '@angular/core';
|
||||
|
||||
constructor(@Inject(PLATFORM_ID) private platformId: Object) {}
|
||||
|
||||
ngOnInit() {
|
||||
if (isPlatformBrowser(this.platformId)) {
|
||||
// Nur im Browser ausführen
|
||||
window.scrollTo(0, 0);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Production Deployment mit PM2
|
||||
|
||||
Für dauerhaften Betrieb (Server-Umgebung):
|
||||
|
||||
```bash
|
||||
# PM2 global installieren
|
||||
npm install -g pm2
|
||||
|
||||
# Production Build
|
||||
npm run build:ssr
|
||||
|
||||
# Server mit PM2 starten
|
||||
pm2 start dist/bizmatch/server/server.mjs --name "bizmatch"
|
||||
|
||||
# Auto-Start bei Server-Neustart
|
||||
pm2 startup
|
||||
pm2 save
|
||||
|
||||
# Logs anzeigen
|
||||
pm2 logs bizmatch
|
||||
|
||||
# Server neustarten nach Updates
|
||||
npm run build:ssr && pm2 restart bizmatch
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Unterschiede der Befehle
|
||||
|
||||
| Befehl | SSR | Hot-Reload | Verwendung |
|
||||
|--------|-----|-----------|------------|
|
||||
| `npm start` | ❌ | ✅ | Entwicklung (schnell) |
|
||||
| `npm run dev:ssr` | ✅ | ✅ | Entwicklung mit SSR |
|
||||
| `npm run build:ssr` | ✅ Build | ❌ | Production Build erstellen |
|
||||
| `npm run serve:ssr` | ✅ | ❌ | Production Server starten |
|
||||
|
||||
---
|
||||
|
||||
## Nächste Schritte
|
||||
|
||||
1. Für normale Entwicklung: **`npm start`** verwenden
|
||||
2. Vor Production-Deployment: **`npm run build:ssr`** testen
|
||||
3. SSR-Funktionalität prüfen (siehe "Schritt 4: Testen")
|
||||
4. Bei Problemen: Logs prüfen und obige Lösungen durchgehen
|
||||
|
||||
---
|
||||
|
||||
## Support
|
||||
|
||||
Bei weiteren Problemen:
|
||||
|
||||
1. **Logs prüfen:** `npm run serve:ssr` zeigt Fehler in der Konsole
|
||||
2. **Browser DevTools:** Console + Network Tab
|
||||
3. **Build-Output:** `npm run build:ssr` zeigt Build-Fehler
|
||||
4. **Node-Version:** `node --version` (sollte ≥ v18 sein)

# BizMatch SSR - Technische Dokumentation
|
||||
|
||||
## Was ist Server-Side Rendering (SSR)?
|
||||
|
||||
Server-Side Rendering bedeutet, dass die Angular-Anwendung nicht nur im Browser, sondern auch auf dem Server läuft und HTML vorab generiert.
|
||||
|
||||
---
|
||||
|
||||
## Unterschied: SPA vs. SSR vs. Prerendering
|
||||
|
||||
### 1. Single Page Application (SPA) - OHNE SSR
|
||||
|
||||
**Ablauf:**
|
||||
```
|
||||
Browser → lädt index.html
|
||||
→ index.html enthält nur <app-root></app-root>
|
||||
→ lädt JavaScript-Bundles
|
||||
→ JavaScript rendert die Seite
|
||||
```
|
||||
|
||||
**HTML-Response:**
|
||||
```html
|
||||
<!doctype html>
|
||||
<html>
|
||||
<head><title>BizMatch</title></head>
|
||||
<body>
|
||||
<app-root></app-root> <!-- LEER! -->
|
||||
<script src="main.js"></script>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
**Nachteile:**
|
||||
- ❌ Suchmaschinen sehen leeren Content
|
||||
- ❌ Langsamer "First Contentful Paint"
|
||||
- ❌ Schlechtes SEO
|
||||
- ❌ Kein Social-Media-Preview (Open Graph)
|
||||
|
||||
---
|
||||
|
||||
### 2. Server-Side Rendering (SSR)
|
||||
|
||||
**Ablauf:**
|
||||
```
|
||||
Browser → fragt Server nach /business/123
|
||||
→ Server rendert Angular-App mit Daten
|
||||
→ Server sendet vollständiges HTML
|
||||
→ Browser zeigt sofort Inhalt
|
||||
→ JavaScript lädt im Hintergrund
|
||||
→ Anwendung wird "hydrated" (interaktiv)
|
||||
```
|
||||
|
||||
**HTML-Response:**
|
||||
```html
|
||||
<!doctype html>
|
||||
<html>
|
||||
<head>
|
||||
<title>Restaurant "Zum Löwen" | BizMatch</title>
|
||||
<meta name="description" content="Restaurant in München...">
|
||||
</head>
|
||||
<body>
|
||||
<app-root>
|
||||
<div class="listing-page">
|
||||
<h1>Restaurant "Zum Löwen"</h1>
|
||||
<p>Traditionelles deutsches Restaurant...</p>
|
||||
<!-- Kompletter gerendeter Content! -->
|
||||
</div>
|
||||
</app-root>
|
||||
<script src="main.js"></script>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
**Vorteile:**
|
||||
- ✅ Suchmaschinen sehen vollständigen Inhalt
|
||||
- ✅ Schneller First Contentful Paint
|
||||
- ✅ Besseres SEO
|
||||
- ✅ Social-Media-Previews funktionieren
|
||||
|
||||
**Nachteile:**
|
||||
- ⚠️ Komplexere Konfiguration
|
||||
- ⚠️ Server-Ressourcen erforderlich
|
||||
- ⚠️ Code muss browser- und server-kompatibel sein

### 3. Prerendering (Static Site Generation)
|
||||
|
||||
**Ablauf:**
|
||||
```
|
||||
Build-Zeit → Rendert ALLE Seiten zu statischen HTML-Dateien
|
||||
→ /business/123.html, /business/456.html, etc.
|
||||
→ HTML-Dateien werden auf CDN deployed
|
||||
```
|
||||
|
||||
**Unterschied zu SSR:**
|
||||
- Prerendering: HTML wird **zur Build-Zeit** generiert
|
||||
- SSR: HTML wird **zur Request-Zeit** generiert
|
||||
|
||||
**BizMatch nutzt SSR, NICHT Prerendering**, weil:
|
||||
- Listings dynamisch sind (neue Einträge täglich)
|
||||
- Benutzerdaten personalisiert sind
|
||||
- Suche und Filter zur Laufzeit erfolgen
|
||||
|

|

|
||||
## Wichtige Dateien und ihre Rolle
|
||||
|
||||
### 1. `server.ts` - Express Server
|
||||
|
||||
```typescript
|
||||
const angularApp = new AngularNodeAppEngine();
|
||||
|
||||
server.get('*', (req, res, next) => {
|
||||
angularApp.handle(req) // ← Rendert Angular serverseitig
|
||||
.then((response) => {
|
||||
if (response) {
|
||||
writeResponseToNodeResponse(response, res);
|
||||
}
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
**Rolle:**
|
||||
- HTTP-Server (Express)
|
||||
- Nimmt Requests entgegen
|
||||
- Delegiert an Angular SSR Engine
|
||||
- Sendet gerenderte HTML-Responses zurück
|
||||
|
||||
---
|
||||
|
||||
### 2. `src/main.server.ts` - Server Entry Point
|
||||
|
||||
```typescript
|
||||
import './ssr-dom-polyfill'; // ← WICHTIG: DOM-Mocks laden
|
||||
|
||||
import { bootstrapApplication } from '@angular/platform-browser';
|
||||
import { AppComponent } from './app/app.component';
|
||||
import { config } from './app/app.config.server';
|
||||
|
||||
const bootstrap = () => bootstrapApplication(AppComponent, config);
|
||||
|
||||
export default bootstrap;
|
||||
```
|
||||
|
||||
**Rolle:**
|
||||
- Entry Point für SSR
|
||||
- Lädt DOM-Polyfills **VOR** allen anderen Imports
|
||||
- Bootstrapped Angular im Server-Kontext
|
||||
|
||||
---
|
||||
|
||||
### 3. `dist/bizmatch/server/index.server.html` - Server Template
|
||||
|
||||
**WICHTIG:** Diese Datei wird **beim Build erstellt**, nicht manuell geschrieben!
|
||||
|
||||
```bash
|
||||
# Build-Prozess erstellt automatisch:
|
||||
npm run build:ssr
|
||||
→ dist/bizmatch/server/index.server.html ✅
|
||||
→ dist/bizmatch/server/server.mjs ✅
|
||||
→ dist/bizmatch/browser/index.csr.html ✅
|
||||
```
|
||||
|
||||
**Quelle:**
|
||||
- Angular nimmt `src/index.html` als Vorlage
|
||||
- Fügt SSR-spezifische Meta-Tags hinzu
|
||||
- Generiert `index.server.html` für serverseitiges Rendering
|
||||
- Generiert `index.csr.html` für clientseitiges Rendering (Fallback)
|
||||
|
||||
**Warum nicht im Git?**
|
||||
- Build-Artefakte werden nicht eingecheckt (`.gitignore`)
|
||||
- Jeder Build erstellt sie neu
|
||||
- Verhindert Merge-Konflikte bei generierten Dateien
|
||||
|
||||
**Fehlerquelle bei neuem Laptop:**
|
||||
```
|
||||
git clone → dist/ Ordner fehlt
|
||||
→ index.server.html fehlt
|
||||
→ npm run serve:ssr crasht ❌
|
||||
|
||||
Lösung: → npm run build:ssr
|
||||
→ index.server.html wird erstellt ✅
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 4. `src/ssr-dom-polyfill.ts` - DOM-Mocks
|
||||
|
||||
```typescript
|
||||
const windowMock = {
|
||||
document: { createElement: () => ({ ... }) },
|
||||
localStorage: { getItem: () => null },
|
||||
navigator: { userAgent: 'node' },
|
||||
// ... etc
|
||||
};
|
||||
|
||||
if (typeof window === 'undefined') {
|
||||
(global as any).window = windowMock;
|
||||
}
|
||||
```
|
||||
|
||||
**Rolle:**
|
||||
- Simuliert Browser-APIs in Node.js
|
||||
- Verhindert `ReferenceError: window is not defined`
|
||||
- Ermöglicht die Ausführung von Browser-Code im Server
|
||||
- Kritisch für Libraries wie Leaflet, die `window` erwarten
|
||||
|
||||
**Warum notwendig?**
|
||||
- Angular-Code nutzt `window`, `document`, `localStorage`, etc.
|
||||
- Node.js hat diese APIs nicht
|
||||
- Ohne Polyfills: Crash beim Server-Start
|
||||
|
||||
---
|
||||
|
||||
### 4. `ssr-dom-preload.mjs` - Node.js Preload Script
|
||||
|
||||
```javascript
|
||||
import { isMainThread } from 'node:worker_threads';
|
||||
|
||||
if (!isMainThread) {
|
||||
// Skip polyfills in worker threads (sass, esbuild)
|
||||
} else {
|
||||
globalThis.window = windowMock;
|
||||
globalThis.document = documentMock;
|
||||
}
|
||||
```
|
||||
|
||||
**Rolle:**
|
||||
- Wird beim `dev:ssr` verwendet
|
||||
- Lädt DOM-Mocks **VOR** allen anderen Modulen
|
||||
- Nutzt Node.js `--import` Flag
|
||||
- Vermeidet Probleme mit early imports
|
||||
|
||||
**Verwendung:**
|
||||
```bash
|
||||
NODE_OPTIONS='--import ./ssr-dom-preload.mjs' ng serve
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 5. `app.config.server.ts` - Server-spezifische Config
|
||||
|
||||
Enthält Provider, die nur im Server-Kontext geladen werden:
|
||||
- `provideServerRendering()`
|
||||
- Server-spezifische HTTP-Interceptors
|
||||
- TransferState für API-Daten
|
||||
|
||||
---
|
||||
|
||||
## Rendering-Ablauf im Detail
|
||||
|
||||
### Phase 1: Server-Side Rendering
|
||||
|
||||
```
|
||||
1. Request kommt an: GET /business/restaurant-123
|
||||
|
||||
2. Express Router:
|
||||
→ server.get('*', ...)
|
||||
|
||||
3. AngularNodeAppEngine:
|
||||
→ bootstrapApplication(AppComponent, serverConfig)
|
||||
→ Angular läuft in Node.js
|
||||
|
||||
4. Angular Router:
|
||||
→ Route /business/:slug matched
|
||||
→ ListingDetailComponent wird aktiviert
|
||||
|
||||
5. Component Lifecycle:
|
||||
→ ngOnInit() wird ausgeführt
|
||||
→ API-Call: fetch('/api/listings/restaurant-123')
|
||||
→ Daten werden geladen
|
||||
→ Template wird mit Daten gerendert
|
||||
|
||||
6. TransferState:
|
||||
→ API-Response wird in HTML injiziert
|
||||
→ <script>window.__NG_STATE__ = {...}</script>
|
||||
|
||||
7. Meta-Tags:
|
||||
→ Title-Service setzt <title>
|
||||
→ Meta-Service setzt <meta name="description">
|
||||
|
||||
8. HTML-Output:
|
||||
→ Komplettes HTML mit Daten
|
||||
→ Wird an Browser gesendet
|
||||
```
|
||||
|
||||
**Server-Output:**
|
||||
```html
|
||||
<!doctype html>
|
||||
<html>
|
||||
<head>
|
||||
<title>Restaurant "Zum Löwen" | BizMatch</title>
|
||||
<meta name="description" content="Traditionelles Restaurant...">
|
||||
</head>
|
||||
<body>
|
||||
<app-root>
|
||||
<!-- Vollständig gerenderte Component -->
|
||||
<div class="listing-detail">
|
||||
<h1>Restaurant "Zum Löwen"</h1>
|
||||
<p>Adresse: Hauptstraße 1, München</p>
|
||||
<!-- etc. -->
|
||||
</div>
|
||||
</app-root>
|
||||
|
||||
<!-- TransferState: verhindert doppelte API-Calls -->
|
||||
<script id="ng-state" type="application/json">
|
||||
{"listings":{"restaurant-123":{...}}}
|
||||
</script>
|
||||
|
||||
<script src="main.js" defer></script>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Phase 2: Client-Side Hydration
|
||||
|
||||
```
|
||||
1. Browser empfängt HTML:
|
||||
→ Zeigt sofort gerenderten Content an ✅
|
||||
→ User sieht Inhalt ohne Verzögerung
|
||||
|
||||
2. JavaScript lädt:
|
||||
→ main.js wird heruntergeladen
|
||||
→ Angular-Runtime startet
|
||||
|
||||
3. Hydration beginnt:
|
||||
→ Angular scannt DOM
|
||||
→ Vergleicht Server-HTML mit Client-Template
|
||||
→ Attachiert Event Listener
|
||||
→ Aktiviert Interaktivität
|
||||
|
||||
4. TransferState wiederverwenden:
|
||||
→ Liest window.__NG_STATE__
|
||||
→ Überspringt erneute API-Calls ✅
|
||||
→ Daten sind bereits vorhanden
|
||||
|
||||
5. App ist interaktiv:
|
||||
→ Buttons funktionieren
|
||||
→ Routing funktioniert
|
||||
→ SPA-Verhalten aktiviert
|
||||
```
|
||||
|
||||
**Wichtig:**
|
||||
- **Kein Flickern** (Server-HTML = Client-HTML)
|
||||
- **Keine doppelten API-Calls** (TransferState)
|
||||
- **Schneller First Contentful Paint** (HTML sofort sichtbar)
|
||||
|
||||
---
|
||||
|
||||
## SSR vs. Non-SSR: Was wird wann gerendert?
|
||||
|
||||
### Ohne SSR (`npm start`)
|
||||
|
||||
| Zeitpunkt | Server | Browser |
|
||||
|-----------|--------|---------|
|
||||
| T0: Request | Sendet leere `index.html` | - |
|
||||
| T1: HTML empfangen | - | Leeres `<app-root></app-root>` |
|
||||
| T2: JS geladen | - | Angular startet |
|
||||
| T3: API-Call | - | Lädt Daten |
|
||||
| T4: Rendering | - | **Erst jetzt sichtbar** ❌ |
|
||||
|
||||
**Time to First Contentful Paint:** ~2-3 Sekunden
|
||||
|
||||
---
|
||||
|
||||
### Mit SSR (`npm run serve:ssr`)
|
||||
|
||||
| Zeitpunkt | Server | Browser |
|
||||
|-----------|--------|---------|
|
||||
| T0: Request | Angular rendert + API-Call | - |
|
||||
| T1: HTML empfangen | - | **Inhalt sofort sichtbar** ✅ |
|
||||
| T2: JS geladen | - | Hydration beginnt |
|
||||
| T3: Interaktiv | - | Event Listener attached |
|
||||
|
||||
**Time to First Contentful Paint:** ~200-500ms
|
||||
|
||||
---
|
||||
|
||||
## Prerendering vs. SSR: Wann wird gerendert?
|
||||
|
||||
### Prerendering (Static Site Generation)
|
||||
|
||||
```
|
||||
Build-Zeit (npm run build):
|
||||
→ ng build
|
||||
→ Rendert /business/1.html
|
||||
→ Rendert /business/2.html
|
||||
→ Rendert /business/3.html
|
||||
→ ...
|
||||
→ Alle HTML-Dateien auf Server deployed
|
||||
|
||||
Request-Zeit:
|
||||
→ Nginx sendet vorgefertigte HTML-Datei
|
||||
→ KEIN Server-Side Rendering
|
||||
```
|
||||
|
||||
**Vorteile:**
|
||||
- Extrem schnell (statisches HTML)
|
||||
- Kein Node.js-Server erforderlich
|
||||
- Günstig (CDN-Hosting)
|
||||
|
||||
**Nachteile:**
|
||||
- Nicht für dynamische Daten geeignet
|
||||
- Re-Build bei jeder Änderung nötig
|
||||
- Tausende Seiten = lange Build-Zeit
|
||||
|
||||
---
|
||||
|
||||
### SSR (Server-Side Rendering)
|
||||
|
||||
```
|
||||
Build-Zeit (npm run build:ssr):
|
||||
→ ng build (Client-Bundles)
|
||||
→ ng build (Server-Bundles)
|
||||
→ KEINE HTML-Dateien generiert
|
||||
|
||||
Request-Zeit:
|
||||
→ Node.js Server empfängt Request
|
||||
→ Angular rendert HTML on-the-fly
|
||||
→ Frische Daten aus DB
|
||||
→ Sendet HTML zurück
|
||||
```
|
||||
|
||||
**Vorteile:**
|
||||
- Immer aktuelle Daten
|
||||
- Personalisierte Inhalte
|
||||
- Keine lange Build-Zeit
|
||||
|
||||
**Nachteile:**
|
||||
- Server-Ressourcen erforderlich
|
||||
- Langsamer als Prerendering (Rendering kostet Zeit)
|
||||
- Komplexere Infrastruktur
|
||||
|
||||
---
|
||||
|
||||
### BizMatch: Warum SSR statt Prerendering?
|
||||
|
||||
**Gründe:**
|
||||
|
||||
1. **Dynamische Listings:**
|
||||
- Neue Businesses werden täglich hinzugefügt
|
||||
- Prerendering würde tägliche Re-Builds erfordern
|
||||
|
||||
2. **Personalisierte Daten:**
|
||||
- Benutzer sehen unterschiedliche Inhalte (Favoriten, etc.)
|
||||
- Prerendering kann nicht personalisieren
|
||||
|
||||
3. **Suche und Filter:**
|
||||
- Unendliche Kombinationen von Filtern
|
||||
- Unmöglich, alle Varianten vorzurendern
|
||||
|
||||
4. **Skalierung:**
|
||||
- 10.000+ Listings → Prerendering = 10.000+ HTML-Dateien
|
||||
- SSR = 1 Server, rendert on-demand
|
||||
|
||||

|
||||
|
||||
## Client-Side Hydration im Detail
|
||||
|
||||
### Was ist Hydration?
|
||||
|
||||
**Hydration** = Angular "erweckt" das Server-HTML zum Leben.
|
||||
|
||||
**Ohne Hydration:**
|
||||
- HTML ist statisch
|
||||
- Buttons funktionieren nicht
|
||||
- Routing funktioniert nicht
|
||||
- Kein JavaScript-Event-Handling
|
||||
|
||||
**Nach Hydration:**
|
||||
- Angular übernimmt Kontrolle
|
||||
- Event Listener werden attached
|
||||
- SPA-Routing funktioniert
|
||||
- Interaktivität aktiviert
|
||||
|
||||
---
|
||||
|
||||
### Hydration-Ablauf
|
||||
|
||||
```typescript
|
||||
// 1. Server rendert HTML
|
||||
<button (click)="openModal()">Details</button>
|
||||
|
||||
// 2. Browser empfängt HTML
|
||||
// → Button ist sichtbar, aber (click) funktioniert NICHT
|
||||
|
||||
// 3. Angular-JavaScript lädt
|
||||
// → main.js wird ausgeführt
|
||||
|
||||
// 4. Hydration scannt DOM
|
||||
angular.hydrate({
|
||||
serverHTML: '<button>Details</button>',
|
||||
clientTemplate: '<button (click)="openModal()">Details</button>',
|
||||
|
||||
// Vergleich: HTML matches Template? ✅
|
||||
// → Reuse DOM node
|
||||
// → Attach Event Listener
|
||||
});
|
||||
|
||||
// 5. Button ist jetzt interaktiv
|
||||
// → (click) funktioniert ✅
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Probleme bei Hydration
|
||||
|
||||
#### Problem 1: Mismatch zwischen Server und Client
|
||||
|
||||
**Ursache:**
|
||||
```typescript
|
||||
// Server rendert:
|
||||
<div>Server Time: {{ serverTime }}</div>
|
||||
|
||||
// Client rendert:
|
||||
<div>Server Time: {{ clientTime }}</div> // ← Unterschiedlich!
|
||||
```
|
||||
|
||||
**Folge:**
|
||||
- Angular erkennt Mismatch
|
||||
- Wirft Warnung in Console
|
||||
- Re-rendert Component (Performance-Verlust)
|
||||
|
||||
**Lösung:**
|
||||
- TransferState nutzen für gemeinsame Daten
|
||||
- `isPlatformServer()` für unterschiedliche Logik
|
||||
|
||||
---
|
||||
|
||||
#### Problem 2: Browser-only Code wird im Server ausgeführt
|
||||
|
||||
**Ursache:**
|
||||
```typescript
|
||||
ngOnInit() {
|
||||
window.scrollTo(0, 0); // ← CRASH: window ist undefined im Server
|
||||
}
|
||||
```
|
||||
|
||||
**Lösung:**
|
||||
```typescript
|
||||
import { isPlatformBrowser } from '@angular/common';
|
||||
import { PLATFORM_ID } from '@angular/core';
|
||||
|
||||
constructor(@Inject(PLATFORM_ID) private platformId: Object) {}
|
||||
|
||||
ngOnInit() {
|
||||
if (isPlatformBrowser(this.platformId)) {
|
||||
window.scrollTo(0, 0); // ← Nur im Browser
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## TransferState: Verhindert doppelte API-Calls
|
||||
|
||||
### Problem ohne TransferState
|
||||
|
||||
```
|
||||
Server:
|
||||
→ GET /api/listings/123 ← API-Call 1
|
||||
→ Rendert HTML mit Daten
|
||||
|
||||
Browser (nach JS-Load):
|
||||
→ GET /api/listings/123 ← API-Call 2 (doppelt!)
|
||||
→ Re-rendert Component
|
||||
```
|
||||
|
||||
**Problem:**
|
||||
- Doppelter Netzwerk-Traffic
|
||||
- Langsamere Hydration
|
||||
- Flickern beim Re-Render
|
||||
|
||||
---
|
||||
|
||||
### Lösung: TransferState
|
||||
|
||||
**Server-Side:**
|
||||
```typescript
|
||||
import { TransferState, makeStateKey } from '@angular/platform-browser';
|
||||
|
||||
const LISTING_KEY = makeStateKey<Listing>('listing-123');
|
||||
|
||||
ngOnInit() {
|
||||
this.http.get('/api/listings/123').subscribe(data => {
|
||||
this.transferState.set(LISTING_KEY, data); // ← Speichern
|
||||
this.listing = data;
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**HTML-Output:**
|
||||
```html
|
||||
<script id="ng-state" type="application/json">
|
||||
{"listing-123": {"name": "Restaurant", "address": "..."}}
|
||||
</script>
|
||||
```
|
||||
|
||||
**Client-Side:**
|
||||
```typescript
|
||||
ngOnInit() {
|
||||
const cachedData = this.transferState.get(LISTING_KEY, null);
|
||||
|
||||
if (cachedData) {
|
||||
this.listing = cachedData; // ← Wiederverwenden ✅
|
||||
} else {
|
||||
this.http.get('/api/listings/123').subscribe(...); // ← Nur wenn nicht cached
|
||||
}
|
||||
|
||||
this.transferState.remove(LISTING_KEY); // ← Cleanup
|
||||
}
|
||||
```
|
||||
|
||||
**Ergebnis:**
|
||||
- ✅ Nur 1 API-Call (serverseitig)
|
||||
- ✅ Kein Flickern
|
||||
- ✅ Schnellere Hydration

## Performance-Vergleich
|
||||
|
||||
### Metriken
|
||||
|
||||
| Metrik | Ohne SSR | Mit SSR | Verbesserung |
|
||||
|--------|----------|---------|--------------|
|
||||
| **Time to First Byte (TTFB)** | 50ms | 200ms | -150ms ❌ |
|
||||
| **First Contentful Paint (FCP)** | 2.5s | 0.5s | **-2s ✅** |
|
||||
| **Largest Contentful Paint (LCP)** | 3.2s | 0.8s | **-2.4s ✅** |
|
||||
| **Time to Interactive (TTI)** | 3.5s | 2.8s | -0.7s ✅ |
|
||||
| **SEO Score (Lighthouse)** | 60 | 95 | +35 ✅ |
|
||||
|
||||
**Wichtig:**
|
||||
- TTFB ist langsamer (Server muss rendern)
|
||||
- Aber FCP viel schneller (HTML sofort sichtbar)
|
||||
- User-Wahrnehmung: SSR fühlt sich schneller an

|
||||
## SEO-Vorteile
|
||||
|
||||
### Google Crawler
|
||||
|
||||
**Ohne SSR:**
|
||||
```html
|
||||
<!-- Google sieht nur: -->
|
||||
<app-root></app-root>
|
||||
<script src="main.js"></script>
|
||||
```
|
||||
|
||||
→ ❌ Kein Content indexiert
|
||||
→ ❌ Kein Ranking
|
||||
→ ❌ Keine Rich Snippets
|
||||
|
||||
---
|
||||
|
||||
**Mit SSR:**
|
||||
```html
|
||||
<!-- Google sieht: -->
|
||||
<title>Restaurant "Zum Löwen" | BizMatch</title>
|
||||
<meta name="description" content="Traditionelles Restaurant in München">
|
||||
<h1>Restaurant "Zum Löwen"</h1>
|
||||
<p>Adresse: Hauptstraße 1, 80331 München</p>
|
||||
<div itemscope itemtype="https://schema.org/Restaurant">
|
||||
<span itemprop="name">Restaurant "Zum Löwen"</span>
|
||||
<span itemprop="address">München</span>
|
||||
</div>
|
||||
```
|
||||
|
||||
→ ✅ Vollständiger Content indexiert
|
||||
→ ✅ Besseres Ranking
|
||||
→ ✅ Rich Snippets (Sterne, Adresse, etc.)
|
||||
|
||||
---
|
||||
|
||||
### Social Media Previews (Open Graph)
|
||||
|
||||
**Ohne SSR:**
|
||||
```html
|
||||
<!-- Facebook/Twitter sehen nur: -->
|
||||
<title>BizMatch</title>
|
||||
```
|
||||
|
||||
→ ❌ Kein Preview-Bild
|
||||
→ ❌ Keine Beschreibung
|
||||
|
||||
---
|
||||
|
||||
**Mit SSR:**
|
||||
```html
|
||||
<meta property="og:title" content="Restaurant 'Zum Löwen'" />
|
||||
<meta property="og:description" content="Traditionelles Restaurant..." />
|
||||
<meta property="og:image" content="https://bizmatch.net/images/restaurant.jpg" />
|
||||
<meta property="og:url" content="https://bizmatch.net/business/restaurant-123" />
|
||||
```
|
||||
|
||||
→ ✅ Schönes Preview beim Teilen
|
||||
→ ✅ Mehr Klicks
|
||||
→ ✅ Bessere User Experience
|
||||
|
||||
---
|
||||
|
||||
## Zusammenfassung
|
||||
|
||||
### SSR in BizMatch bedeutet:
|
||||
|
||||
1. **Server rendert HTML vorab** (nicht erst im Browser)
|
||||
2. **Browser zeigt sofort Inhalt** (schneller First Paint)
|
||||
3. **JavaScript hydrated im Hintergrund** (macht HTML interaktiv)
|
||||
4. **Kein Flickern, keine doppelten API-Calls** (TransferState)
|
||||
5. **Besseres SEO** (Google sieht vollständigen Content)
|
||||
6. **Social-Media-Previews funktionieren** (Open Graph Tags)
|
||||
|
||||
### Technischer Stack:
|
||||
|
||||
- **@angular/ssr**: SSR-Engine
|
||||
- **Express**: HTTP-Server
|
||||
- **AngularNodeAppEngine**: Rendert Angular in Node.js
|
||||
- **ssr-dom-polyfill.ts**: Simuliert Browser-APIs
|
||||
- **TransferState**: Verhindert doppelte API-Calls
|
||||
|
||||
### Wann wird was gerendert?
|
||||
|
||||
- **Build-Zeit:** Nichts (kein Prerendering)
|
||||
- **Request-Zeit:** Server rendert HTML on-the-fly
|
||||
- **Nach JS-Load:** Hydration macht HTML interaktiv
|
||||
|
||||
### Best Practices:
|
||||
|
||||
1. Browser-Code mit `isPlatformBrowser()` schützen
|
||||
2. TransferState für API-Daten nutzen
|
||||
3. DOM-Polyfills für Third-Party-Libraries
|
||||
4. Meta-Tags serverseitig setzen
|
||||
5. Server-Build vor Deployment testen
