A React component for entering PIN codes.

Package Exports

  • react-pin-field

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-pin-field) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Installation

yarn add react-pin-field
# or
npm install react-pin-field

Usage

import PinField from "react-pin-field"

Props

type PinFieldProps = {
  className?: string
  length?: number
  validate?: string | string[] | RegExp | ((key: string) => boolean)
  format?: (char: string) => string
  onResolveKey?: (key: string, ref?: HTMLInputElement) => any
  onRejectKey?: (key: string, ref?: HTMLInputElement) => any
  onChange?: (code: string) => void
  onComplete?: (code: string) => void
  style?: React.CSSProperties
} & React.InputHTMLAttributes<HTMLInputElement>

const defaultProps = {
  className: "",
  length: 5,
  validate: /^[a-zA-Z0-9]$/,
  format: key => key,
  onResolveKey: () => {},
  onRejectKey: () => {},
  onChange: () => {},
  onComplete: () => {},
  style: {},
}

Style

You can pass a custom className, a custom style, or override the CSS class .react-pin-field__input. You have also access to .react-pin-field__success when a key is resolved and .react-pin-field__input--error when a key is rejected.

Length

Length of the code (number of characters to type). Default: 5.

Validate

Hook called to validate a char. It can be:

  • A string of allowed characters: abcABC123
  • A list of allowed chars: ["a", "b", "c", "1", "2", "3"]
  • A RegExp: /^[a-zA-Z0-9]$/
  • A function: (char: string) => boolean

Format

Hook called before adding a new char to the code. For example, to set the code to upper case: (char: string) => char.toUpperCase()

Events

  • onResolveKey: called when a char passes successfully the validate function
  • onRejectKey: the opposite of onResolveKey
  • onChange: called when the code changes
  • onComplete: called when the code has been filled
