Base62 Encoding: One particular typical approach is to employ Base62 encoding (which takes advantage of sixty two characters: 0-nine, A-Z, plus a-z) on an integer ID. The ID corresponds towards the entry during the database. This process makes sure that the shorter URL is as short as you can.
Random String Technology: Another approach would be to make a random string of a set size (e.g., 6 characters) and Check out if it’s previously in use from the databases. Otherwise, it’s assigned for the extensive URL.
