Contributing to AI Web Scraper

Thank you for your interest in contributing to the AI Web Scraper project! This document provides guidelines for contributors and showcases the technical architecture.

🎯 Project Vision

Building an enterprise-grade, AI-powered web scraping platform that democratizes intelligent data extraction through natural language processing.

🔧 Technical Architecture

Backend (FastAPI + Python)

app/
├── main.py              # FastAPI application setup, CORS, middleware
├── models.py            # Pydantic schemas for request/response validation
├── api/endpoints/       # RESTful API route handlers
│   ├── scrape.py       # Core scraping endpoint logic
│   └── status.py       # Health check and service status
├── services/           # Business logic layer (Clean Architecture)
│   ├── scraper_service.py    # Web content fetching & cleaning
│   ├── llm_service.py        # AI processing with multi-provider support
│   └── output_service.py     # Multi-format file generation
└── utils/
    ├── config.py       # Environment-based configuration
    └── logger.py       # Structured logging

Frontend (React + TypeScript + Vite)
