React numpad

Financial Contributors on Open Collective Greenkeeper badge BCH compliance npm version PRs Welcome

A numpad for number, date and time, built with and for React. It's written with the extensibility in mind. The idea of this project is to cover the majority of input types in a form.

Demo / Examples

Live demo:


To use React-Numpad, install it from NPM and include it in your own React build process (using Webpack, etc).

npm install --save react-numpad

At this point you can import react-numpad in your application

import NumPad from 'react-numpad';


React-NumPad generates an input field containing the selected value, so you can submit it as part of a standard form. You can also listen for changes with the onChange event property. When the value is changed, onChange(selectedValue) will fire.

React-NumPad is built based on a "main" component (NumPad.js). Following the higher-order component technique, is possible to create new components by simply overriding few common properties.

Custom input

It's possible to override the InputField component by passing your input field as child component of NumPad.

<NumPad.Number onChange={(value) => console.log('value', value)}>
    <button>Click me!</button>


There is only one theme available for now, in /styles folder, numpad. Any css style is customizable using styled components.

It is possible to override a theme by defining an object with the theme properties:

const myTheme = {
  header: {
    primaryColor: '#263238',
    secondaryColor: '#f9f9f9',
    highlightColor: '#FFC107',
    backgroundColor: '#607D8B',
  body: {
    primaryColor: '#263238',
    secondaryColor: '#32a5f2',
    highlightColor: '#FFC107',
    backgroundColor: '#f9f9f9',
  panel: {
    backgroundColor: '#CFD8DC'

<NumPad.Number theme={myTheme}>
