Base62 Encoding: A person typical technique is to implement Base62 encoding (which works by using sixty two figures: 0-9, A-Z, along with a-z) on an integer ID. The ID corresponds towards the entry during the databases. This process makes certain that the short URL is as quick as you possibly can.
Random String Technology: Yet another solution would be to generate a random string of a set duration (e.g., six people) and Verify if it’s by now in use from the databases. Otherwise, it’s assigned on the extended URL.
