## What it is
A React library for formatting numbers in inputs or as text, with a lightweight caret engine that restricts input to specific numeric or string patterns. It supports prefixes, suffixes, thousands separators, input masking, and custom format patterns.

## Use cases
- format currency input in a react form
- mask phone number input with a pattern
- add thousands separators to number inputs
- display formatted numbers as text in react
- restrict user input to numeric patterns
- build a credit card number input field

## When to choose
- you need robust caret handling while users type formatted numbers
- you want prefix/suffix, separators, and masking out of the box
- you need both input formatting and plain text number display

## When to avoid
- you are not using React
- you need arbitrary non-numeric text formatting beyond patterns
- you want a framework-agnostic vanilla JS formatter

## Facets
- artifact type: library
- maturity: stable
- function: form-handling, ui-components
- domain: frontend, web-development
- platform: browser
- tags: react, input-masking, number-formatting, currency-input, nodejs, web-server
