Cleave.js – Format input text content when you are typing


Cleave.js has a simple purpose: to help you format input text content automatically. The idea is to provide an easy way to increase input field readability by formatting your typed data. By using this library, you won’t need to write any mind-blowing regular expressions or mask patterns to format input text.

However, this isn’t meant to replace any validation or mask library, you should still sanitize and validate your data in backend.
