Web Application for Animal Data Submission with Express

This project sets up a basic web application that allows users to submit animal names through a frontend interface. The submitted data is then sent to a backend server using a POST request, where it's stored and can be retrieved.

Backend (server.js)

The backend is built using Node.js and the Express framework.

Setup

• Uses Express for routing and middleware.
• Utilizes body-parser to parse incoming request bodies.
• Enables CORS for cross-origin requests.
• Serves static files from the website directory.

Endpoints

• GET /all: Returns all stored data.
• POST /add: Responds with 'POST received'.
• POST /animal: Accepts a JSON object with an animal name and stores it in an array.

Server Start

The server listens on port 3000 and logs a confirmation message upon successful startup.

Frontend (app.js)

The frontend provides an interface for users to submit animal names and handles the communication with the backend.

Data Submission

• The submitData function triggers when a user submits an animal name.
• Validates the input and sends the data to the server using the postData function.

Data Sending

• The postData function sends a POST request to the server's /animal endpoint.
• Sends data in JSON format and expects a JSON response from the server.
• Logs the server's response or any errors to the console.

Usage

1. Start the backend server by running node server.js in the terminal.
2. Open the frontend interface in a browser.
3. Enter an animal name in the input field and submit. The data will be sent to the server and stored.

Development Tools

• Visual Studio Code: Primary code editor used for development.
• Node.js and Express: Used for backend server setup.
• body-parser: Middleware to handle POST request data.
• CORS: Middleware to handle cross-origin requests.
