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