Base62 Encoding: One particular widespread tactic is to use Base62 encoding (which employs sixty two people: 0-9, A-Z, and also a-z) on an integer ID. The ID corresponds to your entry in the database. This technique makes certain that the shorter URL is as quick as feasible.
Random String Era: An additional technique is to make a random string of a hard and fast length (e.g., six figures) and check if it’s by now in use in the databases. If not, it’s assigned on the long URL.
