TASK DESCRIPTION-- > Task Description: Weather Application Using MERN Stack Overview The goal of this task is to build a weather forecasting web application using the MERN stack (MongoDB, Express.js, React.js, and Node.js). The application will allow users to enter a city name and view the current weather conditions, including temperature, humidity, wind speed, and a weather icon. The weather data will be fetched from a third-party API (like OpenWeatherMap) and presented in a clean and user-friendly interface.

Features

1. Search for Weather by City:
   Users should be able to enter the name of a city and fetch its current weather details.

2. Display Weather Information:
   Once the user inputs a city, the application will display the following weather details:

   • Temperature (in Celsius or Fahrenheit)
   • Weather condition (e.g., sunny, rainy, cloudy)
   • Wind speed
   • Humidity
   • Weather icon (based on the condition, fetched from the weather API)

3. API Integration:
   The application should integrate with a weather API, such as OpenWeatherMap or WeatherAPI, to retrieve real-time weather data.

4. Responsive Design:
   The application should be fully responsive, ensuring it works well on both desktop and mobile devices.

5. Error Handling:
   If a user enters an invalid city or if the weather API fails, the application should display an appropriate error message.

6. User-friendly UI/UX:
   The user interface should be simple, clean, and easy to use. The design should display all relevant weather data clearly.

7. Location-based Weather (optional):
   Optionally, you can implement geolocation features to fetch the weather data of the user's current location using the browser's Geolocation API.

8. Weather History (optional):
   Save the search history of previously searched cities in the backend, so users can see their past searches.

Technology Stack

1. Frontend (React.js):

   • React.js: For building the user interface.
   • Axios or Fetch API: For making HTTP requests to the weather API.
   • React Router: For handling page routing (if applicable).
   • CSS/Bootstrap: For styling the application and ensuring it's responsive.

2. Backend (Node.js + Express.js):

   • Node.js: The runtime environment for building the backend.
   • Express.js: A web application framework for building the server-side functionality.
   • API calls: Use Express to create an endpoint that fetches weather data from the third-party weather API.
   • MongoDB (Optional): Store search history, user preferences, or other data (e.g., past weather searches).

3. Weather API Integration:

   • Use an external weather API (e.g., OpenWeatherMap API or WeatherAPI) to fetch real-time weather information based on city names or geolocation.

4. MongoDB (Optional):

   • If storing search history or user preferences, use MongoDB for database management. Each search can be saved as a record in MongoDB with the city name and weather data.

5. Version Control:

   • Use Git for version control and store your code on GitHub or any other repository hosting service.

Steps to Complete the Task

1. Set up the Backend:

   • Initialize a Node.js project and install necessary dependencies (Express, Axios, etc.).
   • Set up the Express server and create an API endpoint that queries the weather API with the city name provided by the user.
   • Handle errors and edge cases (invalid city names, API errors).

2. Set up the Frontend:

   • Create a React app using create-react-app or your preferred method.
   • Implement the search functionality (input field for city name).
   • Display the weather data received from the backend (temperature, humidity, wind speed, weather description, and icon).

3. Connect Backend and Frontend:

   • Use Axios or Fetch to call the Express API endpoint from the frontend and display the data in the UI.
   • Handle loading states and error messages.

4. Add Styling:

   • Make sure the app is styled properly, responsive, and user-friendly.
   • Use CSS frameworks like Bootstrap or Material-UI for faster development.

5. Optional Features:

   • Implement geolocation-based weather data.
   • Store the search history in MongoDB.
   • Add user authentication (if required) to save user preferences.

6. Testing and Debugging:

   • Test the application to ensure everything works as expected.
   • Debug any issues, handle edge cases, and ensure proper error handling.

7. Deploy the Application:

   • Once the application is ready, deploy it to platforms like Heroku, Vercel, or Netlify for the frontend and backend.

Deliverables

• Source code for the frontend (React.js) and backend (Node.js + Express.js).
• A working weather application hosted on a platform (e.g., Heroku, Netlify).
• Documentation (README) outlining how to run and use the application.
• Optional: Database integration if you implemented search history functionality.

CONCLUSION:) This project will help you get hands-on experience with the MERN stack while building a practical and useful application.
