Base62 Encoding: One frequent technique is to implement Base62 encoding (which employs sixty two figures: 0-9, A-Z, and a-z) on an integer ID. The ID corresponds into the entry from the database. This process makes sure that the small URL is as limited as is possible.
Random String Era: One more strategy is always to create a random string of a fixed size (e.g., six figures) and Examine if it’s already in use within the databases. If not, it’s assigned to your extended URL.
