React Native IMask Plugin

react-native-imask

Read this before using

I can't say that this plugin is production ready, use it on your own risk. React Native Textinput behavior differs from html input, varies by platform and contains several bugs (1, 2), so some things are not possible to implement. Any PRs are welcomed.

Install

npm install react-native-imask

Masked TextInput Example

import {IMaskTextInput} from 'react-native-imask';

<IMaskTextInput
  mask={Number}
  radix="."
  value="123"
  unmask={true} // true|false|'typed'
  onAccept={
    // depending on prop above first argument is
    // `value` if `unmask=false`,
    // `unmaskedValue` if `unmask=true`,
    // `typedValue` if `unmask='typed'`
    (value, mask) => console.log(value)  // probably should update state
  }
  // ...and more mask props in a guide

  // other TextInput props
  editable={true}
  style={{
    height: 40,
    width: '100%',
    borderColor: 'gray',
    borderWidth: 1
  }}
/>

Extend Existing Components

import {IMaskNativeMixin} from 'react-native-imask';

// use `inputRef` to get reference for our custom text input component
const InputComponent = ({inputRef, ...props}) => (
  <TextInput
    ref={inputRef}
    {...props}
  />
);

// wrap component with IMaskNativeMixin
const IMaskTextInput = IMaskNativeMixin(InputComponent);

// use MaskedComponent
<IMaskTextInput
  mask="0000"
  // ...other props
/>
