React Native Credit Card Input

Easy (and good looking) credit-card input for your React Native Project 💳 💳

Code:

<CreditCardInput onChange={this._onChange} />
// or
<LiteCreditCardInput onChange={this._onChange} />

Features

Skeuomorphic credit-card 💳 (inspired by: card, react-native-credit-card)
!!NEW!! Now you could scale the Credit Card for smaller screens
!!NEW!! Now you could use CardView as a Component. example use case: showing saved payment details, etc.
Lite version for smaller screens (or if skeuomorphic is not really your thing)
Credit-card input validations & formatting while you're typing
Form is fully navigatable using keypad
Works on both Android and iOS

Usage

npm i --save react-native-credit-card-input

then add these lines in your react-native codebase

import { CreditCardInput, LiteCreditCardInput } from "react-native-credit-card-input";

<CreditCardInput onChange={this._onChange} />
// or
<LiteCreditCardInput onChange={this._onChange} />

// Note: You'll need to enable LayoutAnimation on android to see LiteCreditCardInput's animations
// UIManager.setLayoutAnimationEnabledExperimental(true);

And then on your onChange handler:

_onChange => form => console.log(form);

// will print:
{
  valid: true, // will be true once all fields are "valid" (time to enable the submit button)
  values: { // will be in the sanitized and formatted form
  	number: "4242 4242",
  	expiry: "06/19",
  	cvc: "300",
  	type: "visa", // will be one of [null, "visa", "master-card", "american-express", "diners-club", "discover", "jcb", "unionpay", "maestro"]
  	name: "Sam",
  	postalCode: "34567",
  },
  status: {  // will be one of ["incomplete", "invalid", and "valid"]
	number: "incomplete",
	expiry: "incomplete",
	cvc: "incomplete",
	name: "incomplete", 
	postalCode: "incomplete",
  },
};

// Notes: 
// cvc, name, & postalCode will only be available when the respective props is enabled (e.g. requiresName, requiresCVC)

Props

NOTES

##CardView

| Property | Type | Description | | --- | --- | --- | |focused | PropTypes.string | Determines the front face of the card| |brand | PropTypes.string | Brand of the credit card| |name | PropTypes.string | Cardholder's name (Use empty string if you need to hide the placeholder) | |number | PropTypes.string | Credit card number (you'll need to the formatting yourself) | |expiry | PropTypes.string | Credit card expiry (should be in MM/YY format)| |cvc | PropTypes.string | Credit card CVC | |placeholder | PropTypes.object | Placeholder texts| |scale | PropTypes.number | Scales the card| |fontFamily | PropTypes.string | Defaults to Courier and monospace in iOS and Android respectively| |imageFront | PropTypes.number | Image for the credit-card | |imageBack | PropTypes.number | Image for the credit-card | |customIcons | PropTypes.object | brand icons for CardView. see ./src/Icons.js for details |

Note on additionalInputsProps

additionalInputsProps gives you more control over the inputs in LiteCreditCardInput and CreditCardInput. An example object is as follows:

addtionalInputsProps = {
  name: {
    defaultValue: 'my name',
    maxLength: 40,
  },
  postalCode: {
    returnKeyType: 'go',
  },
};

The above would set the default value of the name field to my name and limit the input to a maximum of 40 character. In addition, it would set the returnKeyType of the postalcode field to go.

Methods

setValues

Set values into credit card form

	// sets 4242 on credit card number field
	// other fields will stay unchanged
	this.refs.CCInput.setValues({ number: "4242" });

Known issues: clearing a field e.g. setValues({ expiry: "" }) will trigger the logic to move to previous field and trigger other kind of weird side effects. PR plz

focus

focus on to specified field

	// focus to expiry field
	this.refs.CCInput.focus("expiry");

Example

Expo Snack

In the example directory, run:

npm install

# or

Breaking Changes from 0.2.*

cardViewSize prop are removed from CreditCardInput, use cardScale instead (because changing the size will break most of the texts)
bgColor prop are removed from CreditCardInput, ask your designer friend to make a credit card image instead (or use the prebundled image)
imageFront and imageBack props are renamed to cardImageFront and cardImageBack respectively,
Android monospace fonts doesn't looks as nice as iOS Courier, bundle custom fonts into your app and override the default using cardFontFamily instead
