Distributed Crawler & Price Tracker

Calisan Servisler
-----------------
- Frontend: http://localhost:3000
- Controller API: http://localhost:8000
- RabbitMQ Panel: http://localhost:15672
- PostgreSQL: localhost:5433
- Worker Pool: docker-compose scale ile yatay olceklenebilir

Klasor Yapisi
-------------
- controller/: FastAPI controller uygulamasi
- worker/: Python crawler worker servisi
- frontend/: React + Vite frontend uygulamasi
- infra/: Veritabani baslangic semasi
- docker-compose.yml: Servis orkestrasyonu

Calistirma
----------
Proje dizinine girin:

    cd ~/Desktop/distributed-crawler

Servisleri arka planda baslatin:

    docker-compose up -d --build --force-recreate --scale worker=4

Servis durumunu kontrol edin:

    docker-compose ps

Backend saglik kontrolu:

    curl http://localhost:8000/health

Demo verisini hazirlayin:

    curl -X POST http://localhost:8000/demo/setup

Frontend'e girin:

    http://localhost:3000

    Kullanici adi: admin
    Sifre: admin

Temel API Endpointleri
----------------------
- GET /health: Controller, veritabani ve RabbitMQ saglik durumu
- POST /enqueue: Tek URL tarama gorevi olusturur
- POST /enqueue/batch: Birden fazla URL gorevi olusturur
- GET /results: Son crawler sonuclarini listeler
- GET /stats: Sistem metriklerini getirir

Sorun Giderme
-------------
Container'lar calismiyorsa:

    docker-compose down --remove-orphans
    docker-compose up -d --build --force-recreate --scale worker=4

Health endpoint cevap vermiyorsa:

    docker-compose logs controller

Worker gorev almiyorsa:

    docker-compose logs worker

RabbitMQ kuyruğunu kontrol etmek icin:

    http://localhost:15672

Projeyi durdurmak icin:

    docker-compose down
