Base62 Encoding: One particular typical technique is to utilize Base62 encoding (which makes use of sixty two characters: 0-9, A-Z, as well as a-z) on an integer ID. The ID corresponds on the entry inside the databases. This method ensures that the brief URL is as small as you can.
Random String Technology: A different technique is usually to generate a random string of a fixed size (e.g., 6 figures) and Check out if it’s currently in use during the database. Otherwise, it’s assigned to your extended URL.
