Base62 Encoding: Just one common solution is to use Base62 encoding (which utilizes 62 characters: 0-nine, A-Z, and a-z) on an integer ID. The ID corresponds towards the entry within the databases. This technique makes certain that the limited URL is as limited as feasible.
Random String Era: One more strategy should be to generate a random string of a set length (e.g., six characters) and Verify if it’s currently in use within the database. Otherwise, it’s assigned to the very long URL.
