👥 Website Visitor Count (Serverless + Terraform)

This repository contains a serverless solution to count website visits using AWS Lambda, API Gateway, and DynamoDB. It includes:

• A Python Lambda function that increments a visitor counter stored in DynamoDB.
• A JavaScript snippet to call the API and display the current count on a web page.
• Terraform files to deploy the entire infrastructure automatically.

---

🔧 How It Works

1. A user visits your website.
2. A JavaScript script calls your deployed API Gateway endpoint.
3. The Lambda function:
   • Retrieves the current visitor count from DynamoDB.
   • Increments the count.
   • Returns the updated count as JSON.
4. The website displays the count dynamically.
