    A React component for <input> masking, built on top of inputmask-core.

    This project has never been used by its author, other than while making it.

    Live Demo



    npm install react-maskedinput --save

    Browser bundle

    The browser bundle exposes a global MaskedInput variable and expects to find a global React variable to work with.


    Give MaskedInput a mask and an onChange callback:

    import React from 'react'
    import MaskedInput from 'react-maskedinput'
    class CreditCardDetails extends React.Component {
      state = {
        card: '',
        expiry: '',
        ccv: ''
      _onChange = (e) => {
      render() {
        return <div className="CreditCardDetails">
            Card Number:{' '}
            <MaskedInput mask="1111 1111 1111 1111" name="card" size="20" onChange={this._onChange}/>
            Expiry Date:{' '}
            <MaskedInput mask="11/1111" name="expiry" placeholder="mm/yyyy" onChange={this._onChange}/>
            CCV:{' '}
            <MaskedInput mask="111" name="ccv" onChange={this._onChange}/>

    Create some wrapper components if you have a masking configuration which will be reused:

    function CustomInput(props) {
      return <MaskedInput
          'W': {
            validate(char) { return /\w/.test(char ) },
            transform(char) { return char.toUpperCase() }


    mask : string

    The masking pattern to be applied to the <input>.

    See the inputmask-core docs for supported formatting characters.

    onChange : (event: SyntheticEvent) => any

    A callback which will be called any time the mask's value changes.

    This will be passed a SyntheticEvent with the input accessible via as usual.

    Note: this component currently calls onChange directly, it does not generate an onChange event which will bubble up like a regular <input> component, so you must pass an onChange if you want to get a value back out.

    formatCharacters: Object

    Customised format character definitions for use in the pattern.

    See the inputmask-core docs for details of the structure of this object.

    placeholderChar: string

    Customised placeholder character used to fill in editable parts of the pattern.

    See the inputmask-core docs for details.

    value : string

    A default value for the mask.

    placeholder : string

    A default placeholder will be generated from the mask's pattern, but you can pass a placeholder prop to provide your own.

    size : number | string

    By default, the rendered <input>'s size will be the length of the pattern, but you can pass a size prop to override this.

    Other props

    Any other props passed in will be passed as props to the rendered <input>, except for the following, which are managed by the component:

    • maxLength - will always be equal to the pattern's .length
    • onKeyDown, onKeyPress & onPaste - will each trigger a call to onChange when necessary
