A dependency-free vanilla JavaScript input masking library that formats user input in text fields for patterns like phone numbers, dates, numbers, and regex constraints. It ships framework plugins for React, Vue, Angular, Svelte, Solid, and React Native, and supports web components and contenteditable.

Use cases

• format phone number input as user types
• mask date input fields in javascript
• restrict input to a regex pattern
• currency/number input with thousand separators
• masked input in react or vue forms
• format ssn or credit card input

When to choose

• you need input masking with no external dependencies
• you use a major framework and want an official plugin
• you need varied mask types (pattern, number, date, regex, dynamic) in one library

When to avoid

• you need masking outside the browser (e.g. server-side formatting)
• you want a full form validation/state management solution rather than just masking
