## What it is
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
