Base62 Encoding: A single popular approach is to work with Base62 encoding (which uses 62 people: 0-nine, A-Z, in addition to a-z) on an integer ID. The ID corresponds on the entry within the databases. This method makes sure that the shorter URL is as brief as you possibly can.
Random String Era: A different technique would be to generate a random string of a fixed size (e.g., 6 figures) and Verify if it’s now in use inside the database. If not, it’s assigned into the prolonged URL.
