Base62 Encoding: Just one widespread tactic is to implement Base62 encoding (which works by using sixty two people: 0-nine, A-Z, and a-z) on an integer ID. The ID corresponds towards the entry during the databases. This technique makes certain that the short URL is as small as is possible.
Random String Era: An additional method would be to produce a random string of a fixed duration (e.g., six figures) and check if it’s already in use from the database. If not, it’s assigned into the very long URL.
