Requirements
Ensure you are running on a hooks-compatible version of React (v16.8 & above).
Installation
npm install react-payment-inputs --save
or install with Yarn if you prefer:
yarn add react-payment-inputs
Usage
By default (as seen above), React Payment Inputs does not come with built-in styling meaning that you can easily adapt React Payment Inputs to your own design system.
However, if you would like to use the built-in styles as seen in the animation above, read "Using the built-in styled wrapper".
With hooks
If you'd like to use the hooks version of React Payment Inputs, you can import usePaymentInputs into your component.
import React from 'react';
import { usePaymentInputs } from 'react-payment-inputs';
export default function PaymentInputs() {
const { meta, getCardNumberProps, getExpiryDateProps, getCVCProps } = usePaymentInputs();
return (
<div>
<input {...getCardNumberProps({ onChange: handleChangeCardNumber })} value={cardNumber} />
<input {...getExpiryDateProps({ onChange: handleChangeExpiryDate })} value={expiryDate} />
<input {...getCVCProps({ onChange: handleChangeCVC })} value={cvc} />
{meta.isTouched && meta.error && <span>Error: {meta.error}</span>}
</div>
);
}
By spreading the prop getter functions (e.g.
{...getCardNumberProps()}) on the inputs as shown above, React Payment Inputs will automatically handle the formatting, focus & validation logic for you.
IMPORTANT: You must place your event handlers (e.g.
onChange,onBlur, etc) inside the prop getter function (e.g.getCardNumberProps()) so the default event handlers in React Payment Inputs don't get overridden.
With render props
If you'd like to use the render props version of React Payment Inputs, you can import PaymentInputsContainer into your component.
The props of <PaymentInputsContainer> are the same as the hook options and the render props are the same as the hook data.
import React from 'react';
import { PaymentInputsContainer } from 'react-payment-inputs';
export default function PaymentInputs() {
return (
<PaymentInputsContainer>
{({ meta, getCardNumberProps, getExpiryDateProps, getCVCProps }) => (
<div>
<input {...getCardNumberProps({ onChange: handleChangeCardNumber })} value={cardNumber} />
<input {...getExpiryDateProps({ onChange: handleChangeExpiryDate })} value={expiryDate} />
<input {...getCVCProps({ onChange: handleChangeCVC })} value={cvc} />
{meta.isTouched && meta.error && <span>Error: {meta.error}</span>}
</div>
)}
</PaymentInputsContainer>
);
}
IMPORTANT: You must place your event handlers (e.g.
onChange,onBlur, etc) inside the prop getter function (e.g.getCardNumberProps()) so the default event handlers in React Payment Inputs don't get overridden.
Using the built-in styled wrapper
Note:
<PaymentInputsWrapper>requires styled-components to be installed as a dependency.
By default, React Payment Inputs does not have built-in styling for it's inputs. However, React Payment Inputs comes with a styled wrapper which combines the card number, expiry & CVC fields seen below:
import React from 'react';
import { PaymentInputsWrapper, usePaymentInputs } from 'react-payment-inputs';
import images from 'react-payment-inputs/images';
export default function PaymentInputs() {
const {
wrapperProps,
getCardImageProps,
getCardNumberProps,
getExpiryDateProps,
getCVCProps
} = usePaymentInputs();
return (
<PaymentInputsWrapper {...wrapperProps}>
<svg {...getCardImageProps({ images })} />
<input {...getCardNumberProps()} />
<input {...getExpiryDateProps()} />
<input {...getCVCProps()} />
</PaymentInputsWrapper>
);
}

data
getCardNumberProps
function(overrideProps)| returnsObject<props>
Returns the props to apply to the card number input.
IMPORTANT: You must place your event handlers (e.g. onChange, onBlur, etc) inside the getCardNumberProps() so the default event handlers in React Payment Inputs don't get overridden.
Example snippet
<input {...getCardNumberProps({ onBlur: handleBlur, onChange: handleChange })} />
getExpiryDateProps
function(overrideProps)| returnsObject<props>
Returns the props to apply to the expiry date input.
IMPORTANT: You must place your event handlers (e.g. onChange, onBlur, etc) inside the getExpiryDateProps() so the default event handlers in React Payment Inputs don't get overridden.
Example snippet
<input {...getExpiryDateProps({ onBlur: handleBlur, onChange: handleChange })} />
getCVCProps
function(overrideProps)| returnsObject<props>
Returns the props to apply to the CVC input.
IMPORTANT: You must place your event handlers (e.g. onChange, onBlur, etc) inside the getCVCProps() so the default event handlers in React Payment Inputs don't get overridden.
Example snippet
<input {...getCVCProps({ onBlur: handleBlur, onChange: handleChange })} />
getZIPProps
function(overrideProps)| returnsObject<props>
Returns the props to apply to the ZIP input.
IMPORTANT: You must place your event handlers (e.g. onChange, onBlur, etc) inside the getZIPProps() so the default event handlers in React Payment Inputs don't get overridden.
Example snippet
<input {...getZIPProps({ onBlur: handleBlur, onChange: handleChange })} />
getCardImageProps
function({ images })| returnsObject<props>
Returns the props to apply to the card image SVG.
This function only supports SVG elements currently. If you have a need for another format, please raise an issue.

Using a third-party UI library
React Payment Inputs allows you to integrate into pretty much any React UI library. Below are a couple of examples of how you can fit React Payment Inputs into a UI library using usePaymentInputs. You can also do the same with <PaymentInputsContainer>.
Fannypack
import React from 'react';
import { FieldSet, InputField } from 'fannypack';
import { usePaymentInputs } from 'react-payment-inputs';
import images from 'react-payment-inputs/images';
export default function PaymentInputs() {
const {
meta,
getCardNumberProps,
getExpiryDateProps,
getCVCProps
} = usePaymentInputs();
const { erroredInputs, touchedInputs } = meta;
return (
<FieldSet isHorizontal>
<InputField
// Here is where React Payment Inputs injects itself into the input element.
{...getCardNumberProps()}
placeholder="0000 0000 0000 0000"
label="Card number"
inputRef={getCardNumberProps().ref}
// You can retrieve error state by making use of the error & touched attributes in `meta`.
state={erroredInputs.cardNumber && touchedInputs.cardNumber ? 'danger' : undefined}
validationText={touchedInputs.cardNumber && erroredInputs.cardNumber}
maxWidth="15rem"
/>
<InputField
{...getExpiryDateProps()}
label="Expiry date"
inputRef={getExpiryDateProps().ref}
state={erroredInputs.expiryDate && touchedInputs.expiryDate ? 'danger' : undefined}
validationText={touchedInputs.expiryDate && erroredInputs.expiryDate}
maxWidth="8rem"
/>
<InputField
{...getCVCProps()}
placeholder="123"
label="CVC"
inputRef={getCVCProps().ref}
state={erroredInputs.cvc && touchedInputs.cvc ? 'danger' : undefined}
validationText={touchedInputs.cvc && erroredInputs.cvc}
maxWidth="5rem"
/>
</FieldSet>
);
}
Bootstrap
import React from 'react';
import { FieldSet, InputField } from 'fannypack';
import { usePaymentInputs } from 'react-payment-inputs';
import images from 'react-payment-inputs/images';
export default function PaymentInputs() {
const {
meta,
getCardNumberProps,
getExpiryDateProps,
getCVCProps
} = usePaymentInputs();
const { erroredInputs, touchedInputs } = meta;
return (
<Form>
<Form.Row>
<Form.Group as={Col} style={{ maxWidth: '15rem' }}>
<Form.Label>Card number</Form.Label>
<Form.Control
// Here is where React Payment Inputs injects itself into the input element.
{...getCardNumberProps()}
// You can retrieve error state by making use of the error & touched attributes in `meta`.
isInvalid={touchedInputs.cardNumber && erroredInputs.cardNumber}
placeholder="0000 0000 0000 0000"
/>
<Form.Control.Feedback type="invalid">{erroredInputs.cardNumber}</Form.Control.Feedback>
</Form.Group>
<Form.Group as={Col} style={{ maxWidth: '10rem' }}>
<Form.Label>Expiry date</Form.Label>
<Form.Control
{...getExpiryDateProps()}
isInvalid={touchedInputs.expiryDate && erroredInputs.expiryDate}
/>
<Form.Control.Feedback type="invalid">{erroredInputs.expiryDate}</Form.Control.Feedback>
</Form.Group>
<Form.Group as={Col} style={{ maxWidth: '7rem' }}>
<Form.Label>CVC</Form.Label>
<Form.Control
{...getCVCProps()}
isInvalid={touchedInputs.cvc && erroredInputs.cvc}
placeholder="123"
/>
<Form.Control.Feedback type="invalid">{erroredInputs.cvc}</Form.Control.Feedback>
</Form.Group>
</Form.Row>
</Form>
);
}
Form library examples
React Payment Inputs has support for any type of React form library. Below are examples using Formik & React Final Form.
Formik
import { Formik, Field } from 'formik';
import { PaymentInputsWrapper, usePaymentInputs } from 'react-payment-inputs';
function PaymentForm() {
const {
meta,
getCardImageProps,
getCardNumberProps,
getExpiryDateProps,
getCVCProps,
wrapperProps
} = usePaymentInputs();
return (
<Formik
initialValues={{
cardNumber: '',
expiryDate: '',
cvc: ''
}}
onSubmit={data => console.log(data)}
validate={() => {
let errors = {};
if (meta.erroredInputs.cardNumber) {
errors.cardNumber = meta.erroredInputs.cardNumber;
}
if (meta.erroredInputs.expiryDate) {
errors.expiryDate = meta.erroredInputs.expiryDate;
}
if (meta.erroredInputs.cvc) {
errors.cvc = meta.erroredInputs.cvc;
}
return errors;
}}
>
{({ handleSubmit }) => (
<form onSubmit={handleSubmit}>
<div>
<PaymentInputsWrapper {...wrapperProps}>
<svg {...getCardImageProps({ images })} />
<Field name="cardNumber">
{({ field }) => (
<input {...getCardNumberProps({ onBlur: field.onBlur, onChange: field.onChange })} />
)}
</Field>
<Field name="expiryDate">
{({ field }) => (
<input {...getExpiryDateProps({ onBlur: field.onBlur, onChange: field.onChange })} />
)}
</Field>
<Field name="cvc">
{({ field }) => <input {...getCVCProps({ onBlur: field.onBlur, onChange: field.onChange })} />}
</Field>
</PaymentInputsWrapper>
</div>
<Button marginTop="major-2" type="submit">
Submit
</Button>
</form>
)}
</Formik>
);
}
React Final Form
import { Form, Field } from 'react-final-form';
import { PaymentInputsWrapper, usePaymentInputs } from 'react-payment-inputs';
function PaymentForm() {
const {
meta,
getCardImageProps,
getCardNumberProps,
getExpiryDateProps,
getCVCProps,
wrapperProps
} = usePaymentInputs();
return (
<Form
onSubmit={data => console.log(data)}
validate={() => {
let errors = {};
if (meta.erroredInputs.cardNumber) {
errors.cardNumber = meta.erroredInputs.cardNumber;
}
if (meta.erroredInputs.expiryDate) {
errors.expiryDate = meta.erroredInputs.expiryDate;
}
if (meta.erroredInputs.cvc) {
errors.cvc = meta.erroredInputs.cvc;
}
return errors;
}}
>
{({ handleSubmit }) => (
<form onSubmit={handleSubmit}>
<div>
<PaymentInputsWrapper {...wrapperProps}>
<svg {...getCardImageProps({ images })} />
<Field name="cardNumber">
{({ input }) => (
<input {...getCardNumberProps({ onBlur: input.onBlur, onChange: input.onChange })} />
)}
</Field>
<Field name="expiryDate">
{({ input }) => (
<input {...getExpiryDateProps({ onBlur: input.onBlur, onChange: input.onChange })} />
)}
</Field>
<Field name="cvc">
{({ input }) => <input {...getCVCProps({ onBlur: input.onBlur, onChange: input.onChange })} />}
</Field>
</PaymentInputsWrapper>
</div>
<Button marginTop="major-2" type="submit">
Submit
</Button>
</form>
)}
</Form>
);
}
Customising the in-built style wrapper
React Payment Input's default style wrapper can be customized by supplying a styles prop.
import { css } from 'styled-components';
import { usePaymentInputs, PaymentInputsWrapper } from 'react-payment-inputs';
function PaymentForm() {
const {
getCardNumberProps,
getExpiryDateProps,
getCVCProps,
wrapperProps
} = usePaymentInputs();
return (
<PaymentInputsWrapper
{...wrapperProps}
styles={{
fieldWrapper: {
base: css`
margin-bottom: 1rem;
`
},
inputWrapper: {
base: css`
border-color: green;
`,
errored: css`
border-color: maroon;
`,
focused: css`
border-color: unset;
box-shadow: unset;
outline: 2px solid blue;
outline-offset: 2px;
`
},
input: {
base: css`
color: green;
`,
errored: css`
color: maroon;
`,
cardNumber: css`
width: 15rem;
`,
expiryDate: css`
width: 10rem;
`,
cvc: css`
width: 5rem;
`
},
errorText: {
base: css`
color: maroon;
`
}
}}
>
<input {...getCardNumberProps()} />
<input {...getExpiryDateProps()} />
<input {...getCVCProps()} />
</PaymentInputsWrapper>
);
}
Custom card images
The card images can be customized by passing the images attribute to getCardImageProps({ images }). The images object must consist of SVG paths.
import { css } from 'styled-components';
import { usePaymentInputs, PaymentInputsWrapper } from 'react-payment-inputs';
const images = {
mastercard: (
<g fill="none" fillRule="evenodd">
<rect fill="#252525" height="16" rx="2" width="24" />
<circle cx="9" cy="8" fill="#eb001b" r="5" />
<circle cx="15" cy="8" fill="#f79e1b" r="5" />
<path
d="m12 3.99963381c1.2144467.91220633 2 2.36454836 2 4.00036619s-.7855533 3.0881599-2 4.0003662c-1.2144467-.9122063-2-2.36454837-2-4.0003662s.7855533-3.08815986 2-4.00036619z"
fill="#ff5f00"
/>
</g>
)
}
function PaymentForm() {
const {
getCardNumberProps,
getExpiryDateProps,
getCVCProps,
getCardImageProps,
wrapperProps
} = usePaymentInputs();
return (
<PaymentInputsWrapper {...wrapperProps}>
<svg {...getCardImageProps({ images })} />
<input {...getCardNumberProps()} />
<input {...getExpiryDateProps()} />
<input {...getCVCProps()} />
</PaymentInputsWrapper>
);
