SPRING BREAK

Besides implementing backend endpoints and UI components for task and garden management, I integrated the Open-Meteo API to provide real-time weather data in our mobile application.

The WeatherWidget component allows users to view current weather updates in their selected city (based on profile location). It fetches meteorological data from the Open-Meteo API and displays temperature, humidity, wind speed, and apparent temperature.

This feature is useful in a garden-focused task planning platform where:

• Gardeners can check weather conditions before scheduling or executing outdoor tasks.
• Community members can prepare for adverse weather when planning garden events.
• The system becomes more context-aware and user-friendly.

• Input: city prop passed to the component (e.g., "Ankara", "Istanbul"), coming from the user’s profile data.

• Processing:

• The component uses the city name to get latitude & longitude via Open-Meteo’s Geocoding API (/v1/search?name=CityName).

• It then sends a GET request to the Forecast API using the coordinates.

• Retrieves current weather conditions.

• Output: JSON response is parsed and displayed using styled React Native components within the app.

A logged-in user from Ankara opens the mobile app. The app fetches their city from their profile and sends:

GET https://geocoding-api.open-meteo.com/v1/search?name=Ankara&count=1

Receives:

{
  "results": [
    {
      "latitude": 39.9208,
      "longitude": 32.8541,
      "name": "Ankara"
    }
  ]
}

Then sends:

GET https://api.open-meteo.com/v1/forecastlatitude=39.9208&longitude=32.8541&current=temperature_2m,apparent_temperature,weather_code,wind_speed_10m,relative_humidity_2m&timezone=auto

Receives:

{
   "current": [
    {
     "temperature_2m": 25.4,
     "apparent_temperature": 26.1,
     "wind_speed_10m": 9.8,
     "relative_humidity_2m": 55
    }
  ]
}

This is rendered to the user inside the WeatherWidget.

• Frontend Component: components/WeatherWidget.tsx
• Props: city: string — dynamically passed based on user profile
• Uses: axios, useEffect, useState
• API Endpoints Used: Geocoding: https://geocoding-api.open-meteo.com/v1/search Forecast: https://api.open-meteo.com/v1/forecast
• Display Fields: Temperature, apparent temperature, humidity, wind speed, and city name
• Style: Custom React Native styles with greenish background (#dbeccf)

• Provides real-time context-aware information to users
• Encourages more informed decision making for outdoor gardening tasks
• Lightweight and free-to-use API, with no authentication needed
• Doesn’t require storing weather data locally
• Easy to extend for weekly forecasts or severe weather alerts

This implementation was included in the feature/182-weatherAPI-mobile branch and merged via PR #188.
