Rifm is a tiny, dependency-free React hook and render-prop component for building formatted and masked text inputs while preserving cursor position. It works with native inputs and custom input components, supporting number, phone, date, and other value formatting.

Use cases

• format currency or number inputs with thousand separators in react
• mask phone number input as user types
• add date input mask without losing cursor position
• format credit card number input in react
• enforce casing rules in a text input
• build masked inputs for custom design system components

When to choose

• you need cursor-aware input formatting in React with a tiny footprint
• you want a dependency-free mask solution that works with any input component
• you prefer a simple hook or render-prop API over heavyweight form libraries

When to avoid

• you need type=number or type=date inputs, which Rifm does not support
• you need full form state management and validation, not just input formatting
• you are not using React 16.8 or newer
