🚀 Final Hugging Face Spaces Deployment Summary

✅ Project Successfully Updated for HF Spaces

The Legal Dashboard OCR project has been successfully updated to be fully compatible with Hugging Face Spaces using Docker SDK with custom frontend serving.

📁 Key Changes Made

✅ Dockerfile Updated

FROM python:3.10-slim

WORKDIR /app

# Install required system packages
RUN apt-get update && apt-get install -y \
    build-essential \
    poppler-utils \
    tesseract-ocr \
    libgl1 \
    && rm -rf /var/lib/apt/lists/*

# Copy all project files
COPY . .

# Install Python dependencies
RUN pip install --no-cache-dir -r requirements.txt

EXPOSE 7860

# Run FastAPI app
CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "7860"]

✅ FastAPI Configuration Updated

• Static File Serving: Added app.mount("/", StaticFiles(directory="frontend", html=True), name="static")
• Port Configuration: Running on port 7860 (HF Spaces requirement)
• API Routes: All /api/* endpoints preserved
• CORS: Configured for cross-origin requests

✅ Frontend Structure

• frontend/index.html - Main dashboard entry point
• frontend/improved_legal_dashboard.html - Custom dashboard UI
• Static File Serving - FastAPI serves frontend files directly

🚀 Deployment Ready Features

✅ Core Functionality

• FastAPI Backend - Running on port 7860
• Custom Frontend - Served from /frontend directory
• API Endpoints - Available at /api/*
• Health Checks - Endpoint at /health
• API Documentation - Auto-generated at /docs

✅ Hugging Face Spaces Compatibility

• Docker SDK - Correct metadata in README.md
• Port 7860 - HF Spaces requirement
• Static File Serving - Custom HTML dashboard
• No Gradio Required - Pure FastAPI + custom frontend

🧪 Testing Commands

Local Testing (if Docker available)

# Build image
docker build -t legal-dashboard .

# Run container
docker run -p 7860:7860 legal-dashboard

# Test endpoints
curl http://localhost:7860/          # Dashboard UI
curl http://localhost:7860/health     # Health check
curl http://localhost:7860/docs       # API docs

Manual Testing

# Run FastAPI locally
uvicorn app.main:app --host 0.0.0.0 --port 7860

# Test endpoints
curl http://localhost:7860/          # Dashboard UI
curl http://localhost:7860/health     # Health check
curl http://localhost:7860/docs       # API docs

🚀 Deployment Steps

1. Local Testing

# Test FastAPI locally
uvicorn app.main:app --host 0.0.0.0 --port 7860

# Verify endpoints
- Dashboard: http://localhost:7860
- Health: http://localhost:7860/health
- API Docs: http://localhost:7860/docs

2. Hugging Face Spaces Deployment

1. Create new Space with Docker SDK
2. Push code to Space repository
3. Monitor build logs
4. Verify deployment at port 7860

3. Verification

• Dashboard loads at Space URL
• API endpoints respond correctly
• Custom frontend displays properly
• Health check passes
