Base62 Encoding: One common approach is to implement Base62 encoding (which employs sixty two people: 0-nine, A-Z, and a-z) on an integer ID. The ID corresponds for the entry in the database. This process makes sure that the short URL is as brief as possible.
Random String Technology: Another approach is to crank out a random string of a fixed length (e.g., 6 people) and Test if it’s previously in use inside the databases. Otherwise, it’s assigned towards the long URL.
