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: [gpietro.github.io/react-numpad-demo](https://gpietro.github.io/react-numpad-demo)



## Installation



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



```shell

npm install --save react-numpad

```



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



```shell

import NumPad from 'react-numpad';

```



## Usage



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.



| Property      | Type                 | Default      | Description                                                                                                                        |

```shell

 console.log('value', value)}>

    Click me!



```



## Themes



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:



```shell

const myTheme = {

  header: {

    primaryColor: '#263238',

    secondaryColor: '#f9f9f9',

    highlightColor: '#FFC107',

    backgroundColor: '#607D8B',

  },

  body: {

    primaryColor: '#263238',

    secondaryColor: '#32a5f2',

    highlightColor: '#FFC107',

    backgroundColor: '#f9f9f9',

  },

  panel: {

    backgroundColor: '#CFD8DC'

  }

};



```



## Keyboard support



`0, 1, 2, ... 9`: input number.



`- and .`: input symbol.



`Esc`: close keypad or calendar.



`Enter`: submit value.



## Calendar swipe support



On mobile is possible to switch between months by swipe.

```shell

git clone [email protected]:gpietro/react-numpad.git
