This is a backend service for shortening URLs. Users can provide a long URL, and the service generates a unique short URL. When someone visits the short URL, they are redirected to the original long URL. The backend is built using Node.js, Express, and MongoDB (via Mongoose).

• Shorten long URLs into a unique short URL.
• Store URLs and visit history in MongoDB.
• Keep track of timestamps for each visit.
• Fast and lightweight backend API for URL shortening.

• Node.js
• Express.js
• MongoDB & Mongoose
• shortid (for generating unique short URLs)

1. Short URL Generation:

   • Each long URL is assigned a unique shortId using the shortid library.
   • The shortId is stored along with the original URL in MongoDB.

2. Database Schema:

   • The URL schema has three main fields:
     • shortId: Unique identifier for the short URL.
     • redirectUrl: The original URL to redirect to.
     • visitHistory: Array storing timestamps of each visit.
   • Timestamps are automatically managed using Mongoose’s "timestamps" option.
