Overview

This travel application accepts a location and departure date from the user and returns:

1. Current Weather Forecast if the trip is within a week.
2. Predicted Weather Forecast if the trip is in the future.
3. Image of the travel destination.

Key Features:

• Fetches weather data using the Weatherbit API.
• Retrieves coordinates for the location from the Geonames API.
• Displays images of the travel destination using the Pixabay API.

APIs Used

1. Geonames API

• Purpose: Get latitude and longitude coordinates for a given location.
• API Docs: Geonames API Documentation

2. Weatherbit API

• Purpose: Get weather forecast data (current or predicted) based on coordinates.
• API Docs: Weatherbit API Documentation

3. Pixabay API

• Purpose: Fetch an image of the travel destination based on the location name.
• API Docs: Pixabay API Documentation

How It Works

1. The user submits a location and a departure date via a simple form.
2. The app sends the location to the Geonames API to retrieve the geographical coordinates (latitude and longitude).
3. Based on the proximity of the departure date:
   • If the trip is within 7 days, the app fetches the current weather forecast using the Weatherbit API.
   • If the trip is more than 7 days away, it fetches the predicted forecast from the same API.
4. The app sends the location name to the Pixabay API to retrieve an image of the destination.
5. All this data (weather and image) is displayed to the user.
