Base62 Encoding: 1 popular method is to implement Base62 encoding (which works by using sixty two people: 0-9, A-Z, and also a-z) on an integer ID. The ID corresponds to your entry during the database. This method makes certain that the brief URL is as limited as possible.
Random String Generation: Another tactic is usually to crank out a random string of a hard and fast size (e.g., 6 people) and Examine if it’s presently in use in the databases. If not, it’s assigned towards the lengthy URL.
