Base62 Encoding: One frequent approach is to utilize Base62 encoding (which uses 62 people: 0-9, A-Z, along with a-z) on an integer ID. The ID corresponds towards the entry from the databases. This process makes sure that the shorter URL is as limited as is possible.
Random String Technology: A different solution would be to generate a random string of a fixed length (e.g., six figures) and Check out if it’s presently in use within the database. If not, it’s assigned towards the lengthy URL.
