Base62 Encoding: One prevalent approach is to work with Base62 encoding (which works by using sixty two figures: 0-9, A-Z, along with a-z) on an integer ID. The ID corresponds into the entry within the database. This method ensures that the small URL is as short as you can.
Random String Generation: An additional solution should be to crank out a random string of a set duration (e.g., 6 characters) and Verify if it’s currently in use while in the database. If not, it’s assigned to the extensive URL.
