Base62 Encoding: A single common approach is to employ Base62 encoding (which uses 62 characters: 0-nine, A-Z, in addition to a-z) on an integer ID. The ID corresponds to your entry within the databases. This process makes sure that the limited URL is as small as you can.
Random String Era: A further method will be to create a random string of a fixed length (e.g., six characters) and Look at if it’s already in use within the databases. Otherwise, it’s assigned towards the lengthy URL.
