Stripe.js as a CommonJS module or ES module

This package allows Stripe.js to be imported as a CommonJS module or 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.

Minimum requirements

Node.js: v12.16
TypeScript: v.3.1.1

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 module:

// CommonJS module import
const {loadStripe} = require('@stripe/stripe-js/pure');
// ES module import
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:

// CommonJS module import
const {loadStripe} = require('@stripe/stripe-js/pure');
// ES module import
import {loadStripe} from '@stripe/stripe-js/pure';

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