# Features
* Skeuomorphic credit-card 💳 (inspired by: [card](https://jessepollak.github.io/card/), [react-native-credit-card](https://github.com/sonnylazuardi/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

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

then add these lines in your react-native codebase

```js
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:

```js
_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)
```

#### Note on additionalInputsProps

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


```js
	// 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

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

# Example

[Expo Snack](https://snack.expo.io/@sbycrosz/react-native-credit-card-example)

In the `example` directory, run:

```bash
npm install

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

# Missing Something? Something is not working?
* Open a GitHub issue, or
* Send a pull request :D
* Make sure `npm run lint` passed

# Future Improvement
* Add unit tests
* Create example with [react-native-awesome-card-io](https://github.com/Kerumen/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
