Yet another React component for input masking. Simple and made with attention to UX. Compatible with IE8.

npm install react-input-mask --save

Also you can use it without module bundler

<!-- Load React first -->
<script src="https://unpkg.com/react/dist/react.min.js"></script>
<script src="https://unpkg.com/react-dom/dist/react-dom.min.js"></script>
<!-- Will be exported to window.ReactInputMask -->
<script src="https://unpkg.com/react-input-mask/dist/react-input-mask.min.js"></script>

Mask string. Format characters are:
9: 0-9
a: A-Z, a-z
*: A-Z, a-z, 0-9

Any character can be escaped with backslash, which usually will appear as double backslash in JS strings. For example, German phone mask with unremoveable prefix +49 will look like mask="+4\9 99 999 99" or mask={"+4\\9 99 999 99"}

Character to cover unfilled editable parts of mask. Default character is "_". If set to null or empty string, unfilled parts will be empty, like in ordinary input.

Defines format characters with characters as keys and corresponding RegExp string as values. Default ones:

{
  "9": "[0-9]",
  "a": "[A-Za-z]",
  "*": "[A-Za-z0-9]"
}

Show mask even in empty input without focus.

import React from 'react';
import InputMask from 'react-input-mask';

class PhoneInput extends React.Component {
  render() {
    return <InputMask {...this.props} mask="+4\9 99 999 99" maskChar=" " />;
  }
}
