Firestore Stripe Payments Web SDK
This package helps you integrate your web app client with the
firestore-stripe-payments
extension. It abstracts out all the typical Firestore queries, and
other database interactions necessary to use the extension. Moreover, it provides type
definitions for all the common object types that are used by the extension when processing
payments.
API Reference
Example usage
Initialize the SDK
Start by initializing the Firebase web SDK as usual.
Then, initialize this library by passing in an App
instance obtained from the Firebase
web SDK, and configure the library to use the same Firestore collections you configured
the extension to use.
import { getApp } from "@firebase/app";
import { getStripePayments } from "@stripe/firestore-stripe-payments";
const app = getApp();
const payments = getStripePayments(app, {
productsCollection: "products", // default
customersCollection: "customers", // default
});
// or just
// const payments = getStripePayments(app)
List products and prices
To fetch all the active products along with their prices, call the
getProducts()
function as follows:
import { getProducts } from "@stripe/firestore-stripe-payments";
const products = await getProducts(payments, {
includePrices: true,
activeOnly: true,
});
for (const product of products) {
// ...
}
Note that for N
products, this results in (1 + N)
Firestore queries. Fetching
the products without the prices only requires 1 Firestore query.
You can also specify filters and limits on the product query as follows:
import { getProducts } from "@stripe/firestore-stripe-payments";
const products = await getProducts(payments, {
includePrices: true,
activeOnly: true,
where: [
["metadata.type", "==", "books"],
["metadata.rating", ">=", 4],
],
limit: 10,
});
for (const product of products) {
// ...
}
Start a subscription checkout session
import { createCheckoutSession } from "@stripe/firestore-stripe-payments";
const session = await createCheckoutSession(payments, {
price: myPriceId,
});
window.location.assign(session.url);
Calling createCheckoutSession()
as shown above will use the current page
(window.location.href
) as the success and cancel URLs for the session. Instead you
can specify your own URLs as follows:
import { createCheckoutSession } from "@stripe/firestore-stripe-payments";
const session = await createCheckoutSession(payments, {
price: myPriceId,
success_url: "https://example.com/payments/success",
cancel_url: "https://example.com/payments/cancel",
});
window.location.assign(session.url);
To create a checkout session for more than one item, pass line_items
:
import { createCheckoutSession } from "@stripe/firestore-stripe-payments";
const session = await createCheckoutSession(payments, {
line_items: [
{ price: myPriceId1 },
{ price: myPriceId2 },
],
});
window.location.assign(session.url);
Listen for subscription updates
Once a subscription checkout session has been created, you can listen to the Stripe subscription update events as follows:
import { onCurrentUserSubscriptionUpdate } from "@stripe/firestore-stripe-payments";
onCurrentUserSubscriptionUpdate(
payments,
(snapshot) => {
for (const change in snapshot.changes) {
if (change.type === "added") {
console.log(`New subscription added with ID: ${change.subscription.id}`);
}
}
}
);
