TripLinker is a production-level backend built with Node.js and Express, designed to handle A* Algo to Generator Itinerary, Spatial Graph Grid System to suggeest near by activities and listings, multi-role users (Business/Traveler). This project follows clean architecture principles, focusing on scalability and data integrity.

- Smart Trip: Itinerary Generator based on available listings and activity across multiple fields. Try Itinerary Planner
- Recommendations: Personalized suggestions for Listings and Activities.
- Dual-Account System: Specialized logic for Business accounts (Property/Activity owners) and Standard Travelers (Social "Trips" posts). Sign Up
- Stateless Authentication: Secure JWT-based auth with custom middleware for role-based access control (RBAC).
- Geocoding: Integrated with Nominatim (OSM) for real-time location coordinate mapping.
- Data Integrity: Global error handling with
wrapAsyncwrappers and automated Cloudinary/Review cleanup upon data deletion. - Robust Review System: Integrated feedback loops for listings, activities, and trips.
- Optimized CRUD Engine: High-performance MongoDB schemas designed for efficient image handling and data cleanup.

When the API is triggered, the system converts Source and Destination strings into Latitude/Longitude coordinates.
- Fetch & Memory Load: Uses a Bounding Box / Vector formula to retrieve "Corridor Grids" from MongoDB and loads them into a Node.js Map.
- A Algorithm Solver:* Executes the pathfinding logic and segments the results into Day 1, Day 2, etc., based on
MaxKmconstraints.
Utilizing the Nominatim (OpenStreetMap) API, TripLinker converts addresses into dynamic coordinates to power location-based sorting and map exploration.
The system is optimized for two distinct user flows:
- Travelers: Create personal itineraries and explore social feeds (listings, activities, trips).
- Business Owners: Manage properties/activities and post promotional trips.
- Reviews: A unified system to handle feedback across all entities.
Comprehensive handling of media during creation, editing, and deletion to ensure storage efficiency.
