Redirection Logic: Here is the backend logic that normally takes the quick URL and redirects the user towards the corresponding long URL. This logic is usually implemented in the world wide web server or an application layer.
API: A lot of URL shorteners provide an API making sure that 3rd-bash apps can programmatically shorten URLs and retrieve the original lengthy URLs.

Base62 Encoding: One frequent strategy is to use Base62 encoding (which takes advantage of 62 figures: 0-9, A-Z, in addition to a-z) on an integer ID. The ID corresponds into the entry inside the database. This technique makes sure that the quick URL is as brief as is possible.
Random String Technology: A different approach would be to produce a random string of a fixed length (e.g., six people) and Check out if it’s previously in use from the database. Otherwise, it’s assigned to your very long URL.

ID: A novel identifier for each URL entry.
Very long URL: The initial URL that needs to be shortened.
Shorter URL/Slug: The quick Model on the URL, often saved as a unique string.
