The Concept of a URL Shortener

Introduction to the Concept:

The concept behind a URL shortener is straightforward yet powerful: taking a long, unwieldy URL and converting it into a shorter, more manageable one. This makes sharing URLs easier, especially on platforms with character limits. You always think when looking at one of these websites that they're performing some sort of magic, but after developing this I can see just how simple the implementation is! Simply storing the url to be redirected to via a short code that you generate!

Building the App with Ruby on Rails:

Ruby on Rails' Model-View-Controller (MVC) architecture was ideal for this project. It allowed a clear separation of concerns, making the application easier to manage and extend. Rails' scaffolding was particularly useful, as it quickly generated the foundational code, helping to set up models, views, and controllers with minimal effort.

Initial Setup:

I leveraged Rails’ ability to create database-backed web applications swiftly. The ShortenedUrl model was central to the application, responsible for storing the original URL, generating a short URL, and ensuring the uniqueness of the short URL. The integration of SecureRandom for generating unique short codes was seamless, thanks to Rails' powerful libraries and community gems.
