Base62 Encoding: A single prevalent approach is to employ Base62 encoding (which makes use of 62 figures: 0-nine, A-Z, and also a-z) on an integer ID. The ID corresponds on the entry within the databases. This process makes certain that the small URL is as limited as possible.
Random String Era: A different solution would be to deliver a random string of a hard and fast length (e.g., six figures) and check if it’s presently in use while in the databases. If not, it’s assigned to the long URL.
