Stripe Elements Web Components

🛡⚛️🔰 Any Framework - One Stripe Integration. 💰💵💸

👨‍🎨 Live Demo 👀

🚚 Installation

You should make sure to load stripe.js on your app's index.html, as per Stripe's recommendation, before loading <stripe-elements>. If window.Stripe is not available when you load up the component, it will fail with a reasonably-polite console warning.

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

npm i -S @power-elements/stripe-elements

To pre-build, use Snowpack to build the modules to your app's web_modules directory. See below for usage examples.

npx snowpack

stripe-elements

Stripe.js v3 Card Elements, but it's a Web Component! Supports Shadow DOM.

👨‍🎨 Live Demo 👀

🧙‍♂️ Usage

If you prebuilt with Snowpack, load the module from your web_modules directory

<script type="module" src="/web_modules/@power-elements/stripe-elements/stripe-elements.js"></script>

Alternatively, load the module from the unpkg CDN

<script type="module" src="https://unpkg.com/@power-elements/stripe-elements/stripe-elements.js?module"></script>

Then you can add the element to your page.

<stripe-elements id="stripe"
     action="/payment"
     publishable-key="pk_test_XXXXXXXXXXXXXXXXXXXXXXXX"
></stripe-elements>

See the demos for more comprehensive examples.

Styling

Stripe v3's 'Stripe Elements' are not custom elements, but rather forms hosted by stripe and injected into your page via an iFrame. When we refer to the 'Stripe Element' in this document, we are referring to the hosted Stripe form, not the <stripe-element> custom element. But when I mention the 'element', I mean the custom element.

When you apply CSS to the custom properties available, they're parsed and sent to Stripe, who should apply them to the Stripe Element they return in the iFrame.

• base styles are inherited by all other variants.
• complete styles are applied when the Stripe Element has valid input.
• empty styles are applied when the Stripe Element has no user input.
• invalid styles are applied when the Stripe Element has invalid input.

There are 11 properties for each state that you can set which will be read into the Stripe Element iFrame:

• color
• font-family
• font-size
• font-smoothing
• font-variant
• icon-color
• line-height
• letter-spacing
• text-decoration
• text-shadow
• text-transform
