Stripe Elements for React

React components that help you quickly add Stripe Elements to your React app.

This project is a thin React wrapper around Stripe.js and Stripe Elements. It allows you to add Elements to any React app, and manages the state and lifecycle of Elements for you.

The Stripe.js / Stripe Elements API reference goes into more detail on the various customization options for Elements (e.g. styles, fonts).

Getting started

Installation

First, install react-stripe-elements.

Using yarn:

yarn add react-stripe-elements

Using npm:

npm install --save react-stripe-elements

Using UMD build (exports a global ReactStripeElements object):

<script src="https://unpkg.com/react-stripe-elements@latest/dist/react-stripe-elements.min.js"></script>

Then, load Stripe.js in your application:

<script src="https://js.stripe.com/v3/"></script>

You're good to go!

The Stripe context (StripeProvider)

In order for your application to have access to the Stripe object, let's add StripeProvider to our root React App component:

// index.js
import React from 'react';
import {render} from 'react-dom';
import {StripeProvider} from 'react-stripe-elements';

import MyStoreCheckout from './MyStoreCheckout';

const App = () => {
  return (
    <StripeProvider apiKey="pk_test_12345">
      <MyStoreCheckout />
    </StripeProvider>
  );
};

render(<App />, document.getElementById('root'));

Element groups (Elements)

Next, when you're building components for your checkout form, you'll want to wrap the Elements component around your form. This groups the set of Stripe Elements you're using together, so that we're able to pull data from groups of Elements when you're tokenizing.

// MyStoreCheckout.js
import React from 'react';
import {Elements} from 'react-stripe-elements';

import CheckoutForm from './CheckoutForm';

class MyStoreCheckout extends React.Component {
  render() {
    return (
      <Elements>
        <CheckoutForm />
      </Elements>
    );
  }
}

export default MyStoreCheckout;

Setting up your payment form (injectStripe)

Use the injectStripe Higher-Order Component (HOC) to build your payment form components in the Elements tree. The Higher-Order Component pattern in React can be unfamiliar to those who've never seen it before, so consider reading up before continuing. The injectStripe HOC provides the this.props.stripe property that manages your Elements groups. You can call this.props.stripe.createToken within a component that has been injected to submit payment data to Stripe.

⚠️ NOTE injectStripe cannot be used on the same element that renders the Elements component; it must be used on the child component of Elements. injectStripe returns a wrapped component that needs to sit under <Elements> but above any code where you'd like to access this.props.stripe.

// CheckoutForm.js
import React from 'react';
import {injectStripe} from 'react-stripe-elements';

import AddressSection from './AddressSection';
import CardSection from './CardSection';

class CheckoutForm extends React.Component {
  handleSubmit = (ev) => {
    // We don't want to let default form submission happen here, which would refresh the page.
    ev.preventDefault();

    // Within the context of `Elements`, this call to createToken knows which Element to
    // tokenize, since there's only one in this group.
    this.props.stripe.createToken({name: 'Jenny Rosen'}).then(({token}) => {
      console.log('Received Stripe token:', token);
    });

    // However, this line of code will do the same thing:
    // this.props.stripe.createToken({type: 'card', name: 'Jenny Rosen'});
  }

  render() {
    return (
      <form onSubmit={this.handleSubmit}>
        <AddressSection />
        <CardSection />
        <button>Confirm order</button>
      </form>
    );
  }
}

export default injectStripe(CheckoutForm);

Using individual *Element components

Now, you can use individual *Element components, such as CardElement, to build your form.

// CardSection.js
import React from 'react';
import {CardElement} from 'react-stripe-elements';

class CardSection extends React.Component {
  render() {
    return (
      <label>
        Card details
        <CardElement style={{base: {fontSize: '18px'}}} />
      </label>
    );
  }
};

export default CardSection;

Component reference

<StripeProvider>

All applications using react-stripe-elements must use the <StripeProvider> component, which sets up the Stripe context for a component tree. react-stripe-elements uses the provider pattern (which is also adopted by tools like react-redux and react-intl) to scope a Stripe context to a tree of components. This allows configuration like your API key to be provided at the root of a component tree. This context is then made available to the <Elements> component and individual <*Element> components that we provide.

An integration usually wraps the <StripeProvider> around the application’s root component. This way, your entire application has the configured Stripe context.

Props shape

This component accepts all options that can be passed into Stripe(apiKey, options) as props.

type StripeProviderProps = {
  apiKey: string,
};

<Elements>

The Elements component wraps groups of Elements that belong together. In most cases, you want to wrap this around your checkout form.

Props shape

This component accepts all options that can be passed into stripe.elements(options) as props.

type ElementsProps = {
  locale?: string,
  fonts?: Array<Object>,
  // The full specification for `elements()` options is here: https://stripe.com/docs/elements/reference#elements-options
};

<*Element> components

These components display the UI for Elements, and must be used within StripeProvider and Elements.

Available components

(More to come!)

• CardElement
• CardNumberElement
• CardExpiryElement
• CardCVCElement
• PostalCodeElement

Props shape

These components accept all options that can be passed into elements.create(type, options) as props.

type ElementProps = {
  className?: string,
  elementRef?: (StripeElement) => void,

  // For full documentation on the events and payloads below, see:
  // https://stripe.com/docs/elements/reference#element-on
  onChange?: (changeObject: Object) => void,
  onReady?: () => void,
  onFocus?: () => void,
  onBlur?: () => void,
};

injectStripe HOC

function injectStripe(
  WrappedComponent: ReactClass,
  options?: {
    withRef?: boolean = false,
  }
): ReactClass;

Components that need to initiate Source or Token creations (e.g. a checkout form component) can access stripe.createToken via props of any component returned by the injectStripe HOC factory.

If the withRef option is set to true, the wrapped component instance will be available with the getWrappedInstance() method of the wrapper component. This feature can not be used if the wrapped component is a stateless function component.

Example

const StripeCheckoutForm = injectStripe(CheckoutForm);

The following props will be available to this component:

type FactoryProps = {
  stripe: {
    createToken: (tokenParameters: {type?: string}) => Promise<{token?: Object, error?: Object}>,
    // and other functions available on the `stripe` object,
    // as officially documented here: https://stripe.com/docs/elements/reference#the-stripe-object
  },
};

Troubleshooting

react-stripe-elements may not work properly when used with components that implement shouldComponentUpdate. react-stripe-elements relies heavily on React's context feature and shouldComponentUpdate does not provide a way to take context updates into account when deciding whether to allow a re-render. These components can block context updates from reaching react-stripe-element components in the tree.

For example, when using react-stripe-elements together with react-redux doing the following will not work:

const Component = connect()(injectStripe(_Component));

In this case, the context updates originating from the StripeProvider are not reaching the components wrapped inside the connect function. Therefore, react-stripe-elements components deeper in the tree break. The reason is that the connect function of react-redux implements shouldComponentUpdate and blocks re-renders that are triggered by context changes outside of the connected component.

There are two ways to prevent this issue:

1. Change the order of the functions to have injectStripe be the outermost one:

const Component = injectStripe(connect()(_CardForm));

This works, because injectStripe does not implement shouldComponentUpdate itself, so context updates originating from the redux Provider will still reach all components.

2. You can use the pure: false option for redux-connect:

const Component = connect(mapStateToProps, mapDispatchToProps, mergeProps, {
  pure: false,
})(injectStripe(_CardForm));
