Base62 Encoding: One popular solution is to implement Base62 encoding (which utilizes 62 people: 0-9, A-Z, in addition to a-z) on an integer ID. The ID corresponds for the entry from the database. This technique ensures that the shorter URL is as quick as possible.
Random String Generation: One more technique would be to crank out a random string of a hard and fast length (e.g., 6 figures) and Test if it’s already in use inside the databases. Otherwise, it’s assigned into the prolonged URL.
