\n This is a simple URL shortener application built with React Router and Val Town.\n

\n Create short, easy-to-share links that redirect to your long URLs.\n

How it works:

Enter a long URL in the \"Shorten URL\" page
Get a short URL that you can share
When someone visits the short URL, they'll be redirected to your original URL
