🔗 AI-Powered Secure URL Shortener

A full-stack URL shortening platform with authentication, click tracking, user-scoped URL management, and AI-powered slug and webpage summary generation.

The application allows authenticated users to securely create, manage, and track shortened URLs.

It also includes an AI Suggest feature that analyzes the destination webpage and uses Gemini to generate a meaningful short URL slug and concise summary.

🚀 Live Demo

Live App:
https://url-shortener-app-topaz.vercel.app

GitHub Repository:
https://github.com/Developer-Sohail786/url-shortener-app

✨ Core Features

🔗 Secure URL Generation

Create custom short URLs
Prevent duplicate short URL codes
Associate URLs with individual user accounts
Store URL summaries
Server-side authentication before URL creation
Store click counts and timestamps

🤖 AI-Powered URL Suggestions

The application includes an AI Suggest feature powered by Google Gemini.

When a user enters a destination URL:

The frontend sends the URL to /api/ai-generate.
The server fetches the destination webpage.
The webpage HTML is inspected.
The application attempts to extract the <title> tag.
If unavailable, it attempts to extract og:title.
The URL and extracted title are sent to Gemini.
Gemini generates:
- A concise webpage summary
- A clean, lowercase, hyphen-separated URL slug

The generated slug and summary are returned to the frontend.

🔐 Authentication

Authentication is implemented using NextAuth with JWT sessions.

Credentials Authentication

User registration
Email and password login
Password hashing with bcryptjs
Case-normalized email lookup
Invalid credential handling
JWT-based sessions

Google OAuth

Google login
Automatic user creation for first-time Google users
MongoDB user ID stored in the JWT
Authenticated user ID available through the session

🛡️ Route Protection

Authenticated routes are protected using server-side session validation.

Protected Routes

/shorten

Only authenticated users can access the URL management dashboard.

Authentication-only Routes

/login
/register

Authenticated users are redirected to:

/shorten

Implementation

Route protection uses:

getServerSession()
authOptions
redirect()
force-dynamic
Server-side session validation

The current app/middleware.js does not perform route protection. Protection is implemented directly in the relevant server-rendered pages and API routes.

📊 URL Dashboard

The /shorten page provides a dashboard for managing generated URLs.

Dashboard Features

View all generated URLs
View original destination URL
View shortened URL
View AI-generated summary
View total clicks
View creation date
Copy shortened URL
Delete URLs
Responsive table layout

The dashboard fetches the user's URLs when the page loads and refreshes them when the browser window receives focus.

📈 Click Tracking

Shortened URLs support click tracking.

When a user opens a shortened URL:

/shorturl
    │
    ▼
Find URL in MongoDB
    │
    ▼
Increment clicks using $inc
    │
    ▼
Redirect to original URL

MongoDB's atomic $inc operation is used to increment the click count.

Tracked fields include:

clicks
createdAt
lastClickedAt

lastClickedAt is currently initialized when a URL is created, but the current redirect implementation does not update it when a click occurs.

🔀 URL Redirect System

Short URLs are handled through:

/[shorturl]

The redirect process:

Receives the short URL parameter.
Searches MongoDB for the matching shorturl.
Returns notFound() if the record does not exist.
Validates that the destination begins with http.
Atomically increments the click counter.
Redirects the user to the original destination.

👤 Authorization & User Ownership

Each URL is associated with the authenticated user's ID.

Example URL document:

{
  "url": "https://example.com",
  "shorturl": "example123",
  "summary": "Example webpage",
  "clicks": 0,
  "userId": "user_id",
  "createdAt": "Date",
  "lastClickedAt": null
}

The application ensures that:

Users only retrieve their own URLs.
Users can only delete their own URLs.
URL deletion checks both the document ID and authenticated user's ID.
Unauthenticated API requests are rejected.

🔌 API Routes

Authentication

`POST /api/auth/register`

Creates a new credentials-based user.

`/api/auth/[...nextauth]`

Handles NextAuth authentication requests.

URL Management

`POST /api/generate`

Creates a shortened URL.

Requires:

url
shorturl
summary

Authentication is required.

`GET /api/urls`

Returns URLs belonging to the authenticated user.

Authentication is required.

`POST /api/delete`

Deletes an owned shortened URL.

Authentication is required.

AI

`POST /api/ai-generate`

Generates an AI-powered slug and webpage summary.

Input:

{
  "url": "https://example.com"
}

Output:

{
  "success": true,
  "summary": "Example webpage summary",
  "slug": "example-page"
}

If both Gemini models fail, the endpoint can return fallback data.

🗄️ Database

The project uses MongoDB with the database:

URL_Shorten

Collections

users
url

URL Collection

Field	Description
`url`	Original destination URL
`shorturl`	Short URL identifier
`summary`	AI-generated or supplied summary

`userId`	ID of the URL owner
`createdAt`	URL creation timestamp
`lastClickedAt`	Last-click timestamp field

Users Collection

User records can contain:

name
email
password

🔒 Security

The application demonstrates several security practices.

Authentication Security

NextAuth authentication
JWT sessions
Password hashing with bcryptjs
Google OAuth

Authorization Security

Server-side session validation
User-scoped database queries
Ownership verification during deletion
Protected application routes
Protected API operations

Data Security

Passwords are hashed before storage
URL records contain ownership information
Database operations are performed server-side
