Base62 Encoding: 1 common solution is to utilize Base62 encoding (which makes use of sixty two figures: 0-9, A-Z, and a-z) on an integer ID. The ID corresponds for the entry during the databases. This process ensures that the small URL is as limited as you possibly can.
Random String Technology: Yet another method should be to make a random string of a hard and fast duration (e.g., six people) and check if it’s currently in use within the databases. If not, it’s assigned towards the extensive URL.
