# Amazon Product Price Tracker

This project is a web application built with Node.js and Express that allows users to track the price history of a product on Amazon and set up price drop alerts. The application utilizes web scraping techniques to extract product information such as name, image, rating, stock details, and description from the provided Amazon product URL.

## Features

1. **Product Information Retrieval**: Users can enter an Amazon product URL, and the application will fetch and display relevant product details such as name, image, rating, stock details, and description.

2. **Price History**: The application keeps track of the product's price history. The prices are stored in a JSON file (`history.json`) with timestamps, allowing users to see how the price has changed over time.

3. **Price Drop Alerts**: Users can set up price drop alerts by providing their email address and a target price. The application uses Node.js `nodemailer` to send an email notification when the product's price drops to or below the specified target.

4. **Periodic Price Checks**: The server periodically checks the current price of the tracked product. If the price is below the target set for any active alerts, an email notification is sent.

1. Clone the repository:

```bash
git clone https://github.com/rithwik003/Worthit.git
