Base62 Encoding: One popular solution is to utilize Base62 encoding (which takes advantage of sixty two characters: 0-nine, A-Z, as well as a-z) on an integer ID. The ID corresponds on the entry during the database. This technique ensures that the limited URL is as brief as feasible.
Random String Generation: A further technique is to generate a random string of a set size (e.g., 6 characters) and Check out if it’s already in use from the database. Otherwise, it’s assigned on the prolonged URL.
