Base62 Encoding: A single prevalent technique is to utilize Base62 encoding (which employs 62 characters: 0-9, A-Z, in addition to a-z) on an integer ID. The ID corresponds to the entry from the database. This process ensures that the small URL is as brief as you can.
Random String Era: Yet another method is usually to make a random string of a hard and fast duration (e.g., six people) and Check out if it’s currently in use inside the databases. If not, it’s assigned to the long URL.
