Base62 Encoding: A single prevalent approach is to work with Base62 encoding (which utilizes 62 figures: 0-9, A-Z, and also a-z) on an integer ID. The ID corresponds into the entry while in the databases. This process ensures that the small URL is as quick as possible.
Random String Technology: An additional tactic should be to deliver a random string of a fixed duration (e.g., six people) and Examine if it’s by now in use in the database. Otherwise, it’s assigned on the long URL.
