Weather App

A dynamic weather app built with Spring Boot, fetching real time weather information for any city using the Open-Meteo API - perfect for quick weather checks!

Features:

• Search for the current weather by city name
• Displays weather information such as temperature, humidity and wind speed
• Built using Spring Boot for the backend and Thymeleaf for rendering the front-end
• Utilises real time data from Open Meteo's weather API

How it works:

• Uses open-Meteo's Geocoding API to retrieve coordinates for the city.
• The location data (longitude, latitude) is passed to Open Meto Weather Forecast API to retrieve the current weather
• The user inputs the name of a city, the app fetches latitude/longitude for that city using Open-Meteo Geocoding API
• The latitude/longitude is then used to retrieve the current weather information from Open-Meteo Weather Forecast API
• The fetched data is then displayed using Thymeleaf

Springboot Architecture:

• Controller Layer:

  • WeatherController.java
  • Handles HTTP requests and interacts with service layer to retrieve the data and present it

• Service Layer:

  • Contains the logic of the application
  • WeatherService.java - Gets coordinates and weather data, creates a weather object and sends it the controller layer
  • GetLocationData.java - Uses Geocoding API to retrieve latitude and longitude
  • GetWeatherData.java - Uses the coordinates to retrieve weather information from Open Forecast API

• Model Layer:

  • WeatherData.java - Defines the structure of the weather data and passed by the controller to the view.

• View Layer:

  • Thymeleaf used to present the weather information dynamically.

Further Work:

• Improve front-end using ReactJS to create a more dynamic and interactive user experience
• Integrate a weekly forecast rather than just the current weather
• Improve form validation and error handling to ensure better input handling

Note:

• The project was initially developed as a console-based application where the user interacted with the system through the command line
• The user is prompted to enter a city or 'no' to exit the application and it retrieved the weather information and printed it in the console
• You can explore the fully completed console-based version of the project as it was at that point in time by visiting: console-based commit
