Base62 Encoding: Just one popular approach is to employ Base62 encoding (which utilizes 62 people: 0-9, A-Z, in addition to a-z) on an integer ID. The ID corresponds into the entry from the database. This method ensures that the limited URL is as short as feasible.
Random String Technology: Yet another strategy is usually to create a random string of a hard and fast size (e.g., six figures) and Check out if it’s currently in use while in the databases. If not, it’s assigned towards the very long URL.
