Cleave.js is a JavaScript library that automatically formats text input fields as the user types, supporting credit card numbers, phone numbers, dates, times, numerals, and custom block patterns. It ships as a vanilla JS library with React and AngularJS integrations, but is now deprecated in favor of cleave-zen.

Use cases

• format credit card numbers as users type in a payment form
• format phone numbers with country-specific patterns
• format date and time inputs like YYYY-MM-DD
• format large numbers with thousand separators
• apply custom delimiter and block patterns to input fields
• add input masking to a React form

When to choose

• you need lightweight, dependency-free input formatting in vanilla JS or React
• you want automatic credit card, phone, date, or numeral formatting without writing regex masks
• you are maintaining a legacy project already using Cleave.js

When to avoid

• you are starting a new project - the library is deprecated and its author recommends cleave-zen
• you need full validation or sanitization - Cleave only formats, it does not validate
• you need a maintained library with active bug fixes and framework support beyond React/AngularJS 1.x
