Weather Monitoring System

Overview

This Weather Monitoring System is a full-stack application that fetches real-time weather data for multiple cities, calculates daily summaries, and provides alerting capabilities based on user-defined thresholds.

Features

Real-time weather data fetching for multiple cities

Daily weather summaries including average, maximum, and minimum temperatures

User-configurable weather alerts

RESTful API for weather data and alerts

Frontend dashboard for data visualization

Tech Stack

Backend: Node.js with Express.js

Frontend: React.js

Database: MongoDB

Prerequisites

Before you begin, ensure you have met the following requirements:

Node.js (v14 or later)

npm (v6 or later)

MongoDB (v4 or later)

An OpenWeatherMap API key

Installation

Clone the repository:

git clone [https://github.com/your-username/weather-monitoring-system.git](https://github.com/your-username/weather-monitoring-system.git)
cd weather-monitoring-system

Install backend dependencies:

npm install

Install frontend dependencies:

cd ./frontend
npm install

Create a .env file in the project directory with the following content:

MONGODB_URI=your_mongodb_connection_string
OPENWEATHERMAP_API_KEY=your_openweathermap_api_key
PORT=5000
MAIL_ID=your_email_id
APP_PASS=your_email_app_password

Create another .env file in ./frontend directory with content:

VITE_API_BASE_URL= your_backend_url (http://localhost:5000)

Running the Application

Start the backend server:

npm start

In a new terminal, start the frontend development server:

cd frontend
npm start

Open your browser and navigate to http://localhost:3000 to view the application.

API Endpoints

GET /api/weather/:city - Get current weather for a city

GET /api/summary/:city - Get daily summary for a city

GET /api/summaries/:city - Get all summaries for a city

POST /api/setAlert - Set a new weather alert

Design Choices

Microservice Architecture: The application is divided into backend and frontend services, allowing for independent scaling and maintenance.

RESTful API: The backend exposes a RESTful API, making it easy to integrate with various frontend frameworks or mobile applications in the future.

Cron Jobs: We use node-cron to schedule periodic weather data fetching, ensuring our database is always up-to-date without overwhelming the OpenWeatherMap API.

MongoDB: Chosen for its flexibility with document-based storage, which is ideal for storing varying weather data structures.

React Hooks: The frontend extensively uses React Hooks for state management and side effects, promoting cleaner and more maintainable code.

Error Handling: Comprehensive error handling is implemented both in the backend and frontend to provide informative feedback to users.

Email Notifications: Nodemailer is used to send email alerts when user-defined weather thresholds are breached.
