Building a Single Page Weather App with JavaScript

A JavaScript-Powered Single-Page Weather App

This project, completed as part of Flatiron School's Phase 1 final assignment, involved building a single-page weather application using only HTML, CSS, and JavaScript. The app fetches real-time weather data from a public API to dynamically display current conditions and a forecast. The "Your Weather Forecast" app is designed to be responsive and user-friendly, providing accurate weather information for any global city. This project proved both rewarding and challenging, solidifying my understanding of Phase 1 concepts through practical application.

Project Requirements & Implementation:

The project adhered to several key requirements:

1. Single-Page Application: The app operates entirely on a single page, dynamically updating the DOM via JavaScript in response to user interactions and API data.

2. API Integration: The application utilizes a public API (OpenWeatherMap) returning at least five distinct data objects, each with at least three attributes. These objects encompass detailed weather information, wind conditions, weather descriptions, city details, and forecast data points.

3. Event Listeners: Three event listeners were implemented using .addEventListener(): one for search button clicks, one for "Enter" key presses (triggering searches), and one for input events (providing dynamic city previews during typing).

4. Array Iteration: The forecast section iterates over the API's data.list array using the .map() method to display the forecast information.

App Features:

• Real-Time Weather Updates: Displays current temperature (Celsius), humidity, wind speed, a weather condition icon, and geographic coordinates.

• 5-Time-Point Forecast: Provides a 3-hourly forecast for the next 15 hours, including date/time, temperature, and weather conditions.

• Dynamic Updates: Data is fetched and displayed dynamically without page reloads, ensuring a smooth user experience.

• Error Handling: The app gracefully handles invalid city inputs, providing user feedback for errors.

Challenges and Solutions:

Key challenges included:

• API Handling: Asynchronous data fetching and API response management required careful study of the OpenWeatherMap documentation and practice with fetch and async/await.

• CSS Styling: Improving my CSS skills was a focus to create an attractive and functional user interface.

• Error Handling: Robust error handling was implemented to manage invalid city names and empty inputs, improving the user experience.

Conclusion:

This project significantly enhanced my skills in asynchronous programming, API interaction, and responsive design. The "Your Weather Forecast" app serves as a practical demonstration of the knowledge gained during Phase 1.
