Base62 Encoding: One particular frequent technique is to implement Base62 encoding (which works by using 62 figures: 0-9, A-Z, along with a-z) on an integer ID. The ID corresponds to your entry while in the database. This method makes sure that the limited URL is as brief as you possibly can.
Random String Technology: One more method should be to make a random string of a hard and fast length (e.g., six people) and Test if it’s by now in use inside the database. Otherwise, it’s assigned for the extensive URL.
