Weatherify

A modern, responsive weather application built with vanilla HTML, CSS, and JavaScript that displays current weather conditions and a 5-day forecast for any city worldwide.

REQUEST- The project requires refinement and there are several features that can be added, therefore you can contribute to the project and make it more efficient.

Features

• 🌤️ Current Weather Display: Shows temperature, weather conditions, and detailed metrics
• 📅 5-Day Forecast: Displays upcoming weather with icons and descriptions
• 🔍 City Search: Search for weather in any city with real-time autocomplete suggestions
• 📱 Responsive Design: Optimized for desktop, tablet, and mobile devices
• 🎨 Modern UI: Clean, glassmorphic design with smooth animations
• ⚡ Real-time Data: Fetches live weather data from OpenWeatherMap API

Live Demo

View the live demo here: (https://weatherify-silk.vercel.app/))

Note: GitHub Pages serves static files only. The app expects a small local (or hosted) Node server that proxies OpenWeatherMap so the API key stays on the server. For the public Pages demo to keep working, maintainers need either a deployed proxy (for example Cloudflare Worker, Vercel serverless, or this server.js on a host) or a separate demo URL that runs behind that proxy.

It is requested that users go for local development in order to access the app

Local development

1. Install Node.js 18 or newer.
2. From the project root, run npm install.
3. Copy .env.example to .env and set OPENWEATHER_API_KEY to your OpenWeatherMap API key.
4. Run npm start and open http://localhost:3000 (or the port shown in the terminal).

Opening index.html directly in the browser (file://) will not work for weather requests, because the UI calls same-origin /api/* routes that are provided by server.js.

Key rotation (security)

If an API key was ever committed to the frontend, revoke it in the OpenWeatherMap dashboard and create a new key. Only store the new key in .env (and in your host’s environment variables), never in script.js or other tracked client files.

Technologies Used

• HTML5: Semantic markup structure
• CSS3: Modern styling with:
  • Flexbox and Grid layouts
  • CSS animations and transitions
  • Glassmorphism effects
  • Responsive design principles
• JavaScript (ES6+): Core functionality with:
  • Async/await for API calls
  • DOM manipulation
  • Event handling
  • Debounced input for autocomplete

API Integration

This app uses the OpenWeatherMap API for weather data. The browser only talks to same-origin routes:

• GET /api/weather → OpenWeatherMap current weather (/data/2.5/weather)
• GET /api/forecast → 5-day forecast (/data/2.5/forecast)
• GET /api/geo → Geocoding (/geo/1.0/direct) for autocomplete

The server adds appid from the OPENWEATHER_API_KEY environment variable. The key is not shipped in script.js.
