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.

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",
  customersCollection: "customers",
});

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}`);
      }
    }
  }
);
