Base62 Encoding: A single frequent approach is to utilize Base62 encoding (which works by using 62 figures: 0-9, A-Z, and also a-z) on an integer ID. The ID corresponds towards the entry inside the databases. This method makes sure that the shorter URL is as limited as you can.
Random String Generation: Another strategy is to crank out a random string of a hard and fast size (e.g., six people) and Look at if it’s presently in use from the database. Otherwise, it’s assigned on the very long URL.
