# React Stripe.js

React components for
[Stripe.js and Elements](https://stripe.com/docs/stripe-js).

[![npm version](https://img.shields.io/npm/v/@stripe/react-stripe-js.svg?style=flat-square)](https://www.npmjs.com/package/@stripe/react-stripe-js)

## Requirements

The minimum supported version of React is v16.8. If you use an older version,
upgrade React to use this library. If you prefer not to upgrade your React
version, we recommend using legacy
[`react-stripe-elements`](https://github.com/stripe/react-stripe-elements).

## Getting started

- [Learn how to accept a payment](https://stripe.com/docs/payments/accept-a-payment?platform=web&ui=elements)
- [Add React Stripe.js to your React app](https://stripe.com/docs/stripe-js/react#setup)
- [Try it out using CodeSandbox](https://codesandbox.io/s/react-stripe-official-q1loc?fontsize=14&hidenavigation=1&theme=dark)

## Documentation

- [React Stripe.js reference](https://stripe.com/docs/stripe-js/react)
- [Migrate from `react-stripe-elements`](docs/migrating.md)
- [Legacy `react-stripe-elements` docs](https://github.com/stripe/react-stripe-elements/#react-stripe-elements)
- [Examples](examples)

### Minimal example

First, install React Stripe.js and
[Stripe.js](https://github.com/stripe/stripe-js).

```sh
npm install @stripe/react-stripe-js @stripe/stripe-js
```

#### Using hooks

```jsx
import React, {useState} from 'react';
import ReactDOM from 'react-dom';
import {loadStripe} from '@stripe/stripe-js';
import {
  PaymentElement,
  Elements,
  useStripe,
  useElements,
} from '@stripe/react-stripe-js';

const CheckoutForm = () => {
  const stripe = useStripe();
  const elements = useElements();

  const [errorMessage, setErrorMessage] = useState(null);

  const handleSubmit = async (event) => {
    event.preventDefault();

    if (elements == null) {
      return;
    }

    // Trigger form validation and wallet collection
    const {error: submitError} = await elements.submit();
    if (submitError) {
      // Show error to your customer
      setErrorMessage(submitError.message);
      return;
    }

    // Create the PaymentIntent and obtain clientSecret from your server endpoint
    const res = await fetch('/create-intent', {
      method: 'POST',
    });

    const {client_secret: clientSecret} = await res.json();

    const {error} = await stripe.confirmPayment({
      //`Elements` instance that was used to create the Payment Element
      elements,
      clientSecret,
      confirmParams: {
        return_url: 'https://example.com/order/123/complete',
      },
    });

    if (error) {
      // This point will only be reached if there is an immediate error when
      // confirming the payment. Show error to your customer (for example, payment
      // details incomplete)
      setErrorMessage(error.message);
    } else {
      // Your customer will be redirected to your `return_url`. For some payment
      // methods like iDEAL, your customer will be redirected to an intermediate
      // site first to authorize the payment, then redirected to the `return_url`.
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <PaymentElement />
      <button type="submit" disabled={!stripe || !elements}>
        Pay
      </button>
      {/* Show error message to your customers */}
      {errorMessage && <div>{errorMessage}</div>}
    </form>
  );
};

const stripePromise = loadStripe('pk_test_6pRNASCoBOKtIshFeQd4XMUh');

const options = {
  mode: 'payment',
  amount: 1099,
  currency: 'usd',
  // Fully customizable with appearance API.
  appearance: {
    /*...*/
  },
};

const App = () => (
  <Elements stripe={stripePromise} options={options}>
    <CheckoutForm />
  </Elements>
);

ReactDOM.render(<App />, document.body);
```

#### Using class components

```jsx
import React from 'react';
import ReactDOM from 'react-dom';
import {loadStripe} from '@stripe/stripe-js';
import {
  PaymentElement,
  Elements,
  ElementsConsumer,
} from '@stripe/react-stripe-js';

class CheckoutForm extends React.Component {
  handleSubmit = async (event) => {
    event.preventDefault();
    const {stripe, elements} = this.props;

    if (elements == null) {
      return;
    }

    // Trigger form validation and wallet collection
    const {error: submitError} = await elements.submit();
    if (submitError) {
      // Show error to your customer
      return;
    }

    // Create the PaymentIntent and obtain clientSecret
    const res = await fetch('/create-intent', {
      method: 'POST',
    });

    const {client_secret: clientSecret} = await res.json();

    const {error} = await stripe.confirmPayment({
      //`Elements` instance that was used to create the Payment Element
      elements,
      clientSecret,
      confirmParams: {
        return_url: 'https://example.com/order/123/complete',
      },
    });

    if (error) {
      // This point will only be reached if there is an immediate error when
      // confirming the payment. Show error to your customer (for example, payment
      // details incomplete)
    } else {
      // Your customer will be redirected to your `return_url`. For some payment
      // methods like iDEAL, your customer will be redirected to an intermediate
      // site first to authorize the payment, then redirected to the `return_url`.
    }
  };

  render() {
    const {stripe} = this.props;
    return (
      <form onSubmit={this.handleSubmit}>
        <PaymentElement />
        <button type="submit" disabled={!stripe}>
          Pay
        </button>
      </form>
    );
  }
}

const InjectedCheckoutForm = () => (
  <ElementsConsumer>
    {({stripe, elements}) => (
      <CheckoutForm stripe={stripe} elements={elements} />
    )}
  </ElementsConsumer>
);

const stripePromise = loadStripe('pk_test_6pRNASCoBOKtIshFeQd4XMUh');

const options = {
  mode: 'payment',
  amount: 1099,
  currency: 'usd',
  // Fully customizable with appearance API.
  appearance: {
    /*...*/
  },
};

const App = () => (
  <Elements stripe={stripePromise} options={options}>
    <InjectedCheckoutForm />
  </Elements>
);

ReactDOM.render(<App />, document.body);
```

### TypeScript support

React Stripe.js is packaged with TypeScript declarations. Some types are pulled
from [`@stripe/stripe-js`](https://github.com/stripe/stripe-js)—be sure to add
`@stripe/stripe-js` as a dependency to your project for full TypeScript support.

Typings in React Stripe.js follow the same
[versioning policy](https://github.com/stripe/stripe-js#typescript-support) as
`@stripe/stripe-js`.
