Base62 Encoding: A single prevalent method is to implement Base62 encoding (which uses 62 figures: 0-nine, A-Z, plus a-z) on an integer ID. The ID corresponds to your entry while in the database. This method makes certain that the shorter URL is as brief as possible.
Random String Era: A different approach is usually to deliver a random string of a set duration (e.g., six figures) and Look at if it’s already in use from the databases. Otherwise, it’s assigned to the very long URL.
