## API Integration

### Google Maps API

- **Purpose**: To display maps, routes, and nearby attractions.

- **Usage**: The Google Maps API is used to dynamically display maps based on user input destinations. It provides route planning and nearby attractions to enhance the travel experience.



### OpenWeatherMap API

- **Purpose**: To provide real-time weather forecasts for destinations.

- **Usage**: This API offers current weather data, forecasts, and weather conditions for any location. It helps users plan their activities according to expected weather conditions.



### Amadeus API

- **Purpose**: For searching and booking flights.

- **Usage**: The Amadeus API allows users to search for and book flights. It integrates multiple airline and booking services to find the best options for the user.



### CORS (Cross-Origin Resource Sharing)

- **Purpose**: To enable the frontend application to make requests to the backend server and third-party APIs securely.

-**Usage**: CORS is configured in the backend to allow requests from the frontend domain, ensuring secure and efficient data exchange. This involves setting appropriate headers to control access and permissions for cross-origin requests.



## Data Flow

### User Inputs

- **Step 1**: Users input their travel details, including destination, travel dates, and interests.

- **Step 2**: These inputs are sent to the backend server for processing.



### API Calls

- **Step 3**: The backend makes API calls to fetch real-time data from Google Maps, OpenWeatherMap, and Amadeus APIs.

- **Step 4**: The responses from these APIs are processed to extract relevant information.



### Data Processing

- **Step 5**: The backend interacts with the SQLite database to store and retrieve user preferences and itineraries.

- **Step 6**: The customized itinerary is generated, including suggestions for places to visit, activities, and dining options.

- **Step 7**: Socket.IO handles real-time communication between multiple users for collaborative itinerary planning.



### Display Results

- **Step 8**: The frontend receives the processed data and displays the customized itinerary, maps, weather forecasts, and booking options to the user.



## User Preferences and Itinerary Customization

The backend processes user preferences to tailor itinerary suggestions. Preferences and itineraries are stored in an SQLite database for personalized recommendations. This includes:

- **Activity Preferences**: Types of activities the user enjoys.

- **Dietary Restrictions**: Information to ensure dining options meet user dietary needs.

- **Budget Constraints**: Ensures the itinerary fits within the user’s budget.

- **Family and Pet-Friendly Options**: Customizes the itinerary based on family and pet-friendly activities and accommodations.



## Collaborative Planning

The application allows users to share their itineraries with friends and family, enabling collaborative trip planning in real-time.



## Mobile Responsiveness

The application is fully responsive, ensuring a seamless user experience across different devices, including smartphones and tablets. This is achieved using Material-UI’s responsive design components and CSS media queries.
