Base62 Encoding: A single common strategy is to employ Base62 encoding (which makes use of sixty two characters: 0-nine, A-Z, along with a-z) on an integer ID. The ID corresponds on the entry in the database. This process makes sure that the shorter URL is as quick as is possible.
Random String Technology: Yet another tactic is to create a random string of a set size (e.g., six people) and check if it’s currently in use inside the database. Otherwise, it’s assigned on the extended URL.
