Base62 Encoding: One particular popular strategy is to employ Base62 encoding (which takes advantage of 62 figures: 0-nine, A-Z, along with a-z) on an integer ID. The ID corresponds on the entry during the databases. This method ensures that the small URL is as small as feasible.
Random String Generation: Yet another solution would be to create a random string of a set size (e.g., 6 characters) and Check out if it’s now in use in the database. Otherwise, it’s assigned into the long URL.
