Base62 Encoding: A single widespread approach is to work with Base62 encoding (which works by using sixty two characters: 0-nine, A-Z, plus a-z) on an integer ID. The ID corresponds on the entry while in the database. This process ensures that the small URL is as limited as feasible.
Random String Era: A different method would be to produce a random string of a hard and fast size (e.g., 6 people) and Check out if it’s currently in use from the database. Otherwise, it’s assigned for the prolonged URL.
