Base62 Encoding: A person typical approach is to utilize Base62 encoding (which uses sixty two people: 0-nine, A-Z, and also a-z) on an integer ID. The ID corresponds for the entry while in the database. This process makes sure that the shorter URL is as small as possible.
Random String Generation: Yet another strategy is to generate a random string of a fixed duration (e.g., six figures) and Look at if it’s by now in use in the databases. Otherwise, it’s assigned towards the very long URL.
