Base62 Encoding: One particular typical strategy is to use Base62 encoding (which takes advantage of 62 people: 0-9, A-Z, as well as a-z) on an integer ID. The ID corresponds into the entry while in the databases. This process ensures that the small URL is as short as possible.
Random String Era: Yet another solution should be to generate a random string of a set size (e.g., 6 people) and check if it’s previously in use during the databases. If not, it’s assigned for the very long URL.
