Base62 Encoding: 1 common approach is to implement Base62 encoding (which makes use of sixty two characters: 0-nine, A-Z, and a-z) on an integer ID. The ID corresponds towards the entry while in the databases. This technique ensures that the brief URL is as quick as possible.
Random String Era: A different solution would be to crank out a random string of a hard and fast length (e.g., six figures) and Check out if it’s now in use within the database. Otherwise, it’s assigned to the long URL.
