About Short It

It is a url shortener application like bitly & dub.sh.
Created using Next.js 14, React Server components and Server actions.
Uses Redis (Vercel KV) to store the urls. Since It is an in memory database it queries data much faster than Disk based databases.
Uses Next auth & github Oauth to implement authentication. It has also implemented protected routes so anonymous user can't access it.
It also uses Next.js dynamic routes & route handlers to implement the redirect logic

How it works

It requires authentication to generate shortened links
Once authenticated user can add links and behind the scene a server action is executed to generate a unique uuid using nanoid and stores the long url as key, value pairs.
It uses dynamic routes to redirect the shortened url to it's associated long url with HTTP 307 status code.
