@stripe/stripe-js

What is @stripe/stripe-js?

The @stripe/stripe-js package is a JavaScript library that allows developers to integrate Stripe's payment processing capabilities into their web applications. It provides a set of tools to create and manage payment elements, handle payment intents, and securely collect payment information.

What are @stripe/stripe-js's main functionalities?

Loading Stripe.js

This code sample demonstrates how to asynchronously load the Stripe.js library using the provided publishable key. The `loadStripe` function returns a Promise that resolves with the Stripe object.

import { loadStripe } from '@stripe/stripe-js';

const stripePromise = loadStripe('pk_test_TYooMQauvdEDq54NiTphI7jx');

Creating a Payment Element

This code sample shows how to use the `Elements` provider to inject the Stripe object into the React component tree and create a `CardElement` that collects the user's card details.

import { Elements } from '@stripe/react-stripe-js';
import { CardElement } from '@stripe/react-stripe-js';

const stripePromise = loadStripe('pk_test_TYooMQauvdEDq54NiTphI7jx');

const CheckoutForm = () => {
  return (
    <Elements stripe={stripePromise}>
      <CardElement />
    </Elements>
  );
};

Handling Payment Intents

This code sample illustrates how to confirm a card payment using a PaymentIntent's client secret. It uses the `confirmCardPayment` method to handle the payment process.

const stripe = await loadStripe('pk_test_TYooMQauvdEDq54NiTphI7jx');

const {error, paymentIntent} = await stripe.confirmCardPayment('{CLIENT_SECRET}', {
  payment_method: {
    card: cardElement,
    billing_details: {
      name: 'Jenny Rosen'
    }
  }
});

This package provides React components for building forms with Stripe Elements. It is similar to @stripe/stripe-js but is designed specifically for React applications. It has been deprecated in favor of @stripe/react-stripe-js, which works with the newer Stripe.js.

braintree-web

Braintree's JavaScript SDK for integrating payment processing. It offers similar functionality to @stripe/stripe-js but is tailored for Braintree's payment platform, which is a different service owned by PayPal.

square-web-sdk

Square's Web Payments SDK is an alternative to @stripe/stripe-js for integrating Square's payment processing services. It provides a different set of APIs and is designed to work with Square's ecosystem.

README

Stripe.js ES Module

Use Stripe.js as an ES module.

Note: To be PCI compliant, you must load Stripe.js directly from https://js.stripe.com. You cannot include it in a bundle or host it yourself. This package wraps the global Stripe function provided by the Stripe.js script as an ES module.

Calling loadStripe always loads the latest version of Stripe.js, regardless of which version of @stripe/stripe-js you use. Updates for this package only impact tooling around the loadStripe helper itself and the TypeScript type definitions provided for Stripe.js. Updates do not affect runtime availability of features of Stripe.js.

Installation

Use npm to install the Stripe.js module:

npm install @stripe/stripe-js

Usage

loadStripe

This function returns a Promise that resolves with a newly created Stripe object once Stripe.js has loaded. It takes the same parameters passed when directly initializing a Stripe instance. If necessary, it will load Stripe.js for you by inserting the Stripe.js script tag. If you call loadStripe in a server environment it will resolve to null.

import {loadStripe} from '@stripe/stripe-js';

const stripe = await loadStripe('pk_test_TYooMQauvdEDq54NiTphI7jx');

We’ve placed a random API key in this example. Replace it with your actual publishable API keys to test this code through your Stripe account.

For more information on how to use Stripe.js, please refer to the Stripe.js API reference or learn to accept a payment with Stripe.

If you have deployed a Content Security Policy, make sure to include Stripe.js in your directives.

TypeScript support

This package includes TypeScript declarations for Stripe.js. We support projects using TypeScript versions >= 3.1.

Some methods in Stripe.js accept and return objects from the Stripe API. The type declarations in @stripe/stripe-js for these objects in will always track the latest version of the Stripe API. If you would like to use these types but are using an older version of the Stripe API, we recommend updating to the latest version, or ignoring and overriding the type definitions as necessary.

Note that we may release new minor and patch versions of @stripe/stripe-js with small but backwards-incompatible fixes to the type declarations. These changes will not affect Stripe.js itself.

Ensuring Stripe.js is available everywhere

To best leverage Stripe’s advanced fraud functionality, ensure that Stripe.js is loaded on every page, not just your checkout page. This allows Stripe to detect suspicious behavior that may be indicative of fraud as customers browse your website.

By default, this module will insert a <script> tag that loads Stripe.js from https://js.stripe.com. This happens as a side effect immediately upon importing this module. If you utilize code splitting or only include your JavaScript app on your checkout page, the Stripe.js script will only be available in parts of your site. To ensure Stripe.js is available everywhere, you can perform either of the following steps:

Import as a side effect

Import @stripe/stripe-js as a side effect in code that will be included throughout your site (e.g. your root module). This will make sure the Stripe.js script tag is inserted immediately upon page load.

import '@stripe/stripe-js';

Manually include the script tag

Manually add the Stripe.js script tag to the <head> of each page on your site. If an existing script tag is already present, this module will not insert a new one. When you call loadStripe, it will use the existing script tag.

<!-- Somewhere in your site's <head> -->
<script src="https://js.stripe.com/v3" async></script>

Importing loadStripe without side effects

If you would like to use loadStripe in your application, but defer loading the Stripe.js script until loadStripe is first called, use the alternative @stripe/stripe-js/pure import path:

import {loadStripe} from '@stripe/stripe-js/pure';

// Stripe.js will not be loaded until `loadStripe` is called
const stripe = await loadStripe('pk_test_TYooMQauvdEDq54NiTphI7jx');

Disabling advanced fraud detection signals

If you would like to disable advanced fraud detection altogether, use loadStripe.setLoadParameters:

import {loadStripe} from '@stripe/stripe-js/pure';

loadStripe.setLoadParameters({advancedFraudSignals: false});
const stripe = await loadStripe('pk_test_TYooMQauvdEDq54NiTphI7jx');

The loadStripe.setLoadParameters function is only available when importing loadStripe from @stripe/stripe-js/pure.
