Base62 Encoding: 1 frequent tactic is to work with Base62 encoding (which uses 62 characters: 0-nine, A-Z, and also a-z) on an integer ID. The ID corresponds into the entry from the databases. This technique makes certain that the shorter URL is as shorter as you can.
Random String Technology: A different tactic will be to crank out a random string of a hard and fast size (e.g., 6 figures) and Examine if it’s currently in use in the database. If not, it’s assigned towards the very long URL.
