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)

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

In the example directory, run:

npm install

react-native run-ios
# or
react-native run-android

• Send a pull request :D
• Make sure npm run lint passed

Future Improvement

• Add unit tests
• Create example with react-native-awesome-card-io

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
