Prompt to Start Development

"Build a fully responsive, visually engaging web application using React for the frontend, Node.js for the backend, and MySQL as the database. The app is an AI-powered intelligence dashboard for Dial‑100 emergency calls. It should feature real-time call data ingestion (every 10 mins), NLP-based classification (crime types, severity, named entities), geospatial visualization (heatmaps by location), and role-based dashboards (SP, DSP, Inspectors). Include correction feedback tools, alert triggers (via WhatsApp/SMS/Email), and access-controlled reporting modules. The UI should be clean, modern (using Tailwind or Material UI), and optimized for desktop and tablet use."

💡 Bonus Tips for Implementation:

Frontend (React):

Use React Router for multi-role views (SP/DSP/Operator).
Integrate Recharts, Leaflet.js, or Mapbox GL for data visualization and maps.
Use Axios for API requests and React Query for caching.
Use Context API or Redux for auth & role-based state.

Backend (Node.js + Express):

Create RESTful APIs for:
- Call ingestion & NLP results
- Dashboard summaries
- Alert configurations
- User management & role-based access
Integrate NLP processing with Python (via child process or microservice, if needed).
Schedule data ingestion every 10 mins using node-cron.

Database (MySQL):

Design schema with tables like:
- calls, classified_calls, officers, stations, alerts, users, audit_logs
Use indexes on time and location fields for fast queries.
Ensure relational integrity between police stations and calls.
