Link Shortener

Link Shortener is a simple service that uses SQLite for storing and managing shortened URLs. This Go-based application provides endpoints to shorten URLs and resolve them back to their original destination.

Features

Shorten URLs: Convert long URLs into shorter, manageable links. Resolve Shortened Links: Redirect shortened links to their original URLs. Delete Shortened Links: Remove a shortened link and ensure it no longer redirects.

Prerequisites

Go (Go 1.18 or later recommended)

Start the application

git clone https://github.com/nilspolek/linkShortener.git
cd linkshortener
make run

Usage

Access a Link

GET http://localhost:8080/<short>

This request redirects to the original URL where short is the shortened link.

Add a URL (POST request)

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

returns

{
  "short": "shortened"
}

Delete a shortened URL (DELETE request):

{
  "destination": "https://example.com"
  "short": ["<shortlink1>, <shortlink2>, ..."]
}

Testing

The project includes tests to verify functionality. Run the tests with:

make test

The tests cover:

GET Request: Verify redirection from shortened link to the original URL. POST and DELETE Requests: Test creating, resolving, and deleting shortened links. Troubleshooting

Server Not Starting: Ensure no other services are running on port 8080. Database Issues: Check logs for errors and ensure the database file has the correct permissions.
