Billing that fits your stack

Billing fits naturally into Remix's data flow. Subscribe in actions, check access in loaders, and redirect to checkout — progressive enhancement included.

app/routes/billing.tsx

import { redirect } from "@remix-run/node";
import { commet } from "~/lib/commet";

export async function action({ request }: ActionFunctionArgs) {
  const form = await request.formData();
  const customerId = form.get("userId") as string;

  await commet.customers.create({
    email: form.get("email") as string,
    id: customerId,
  });

  const sub = await commet.subscriptions.create({
    customerId,
    planCode: "pro",
  });

  return redirect(sub.data.checkoutUrl);
}

import { redirect } from "@remix-run/node";
import { commet } from "~/lib/commet";

export async function action({ request }: ActionFunctionArgs) {
  const form = await request.formData();
  const customerId = form.get("userId") as string;

  await commet.customers.create({
    email: form.get("email") as string,
    id: customerId,
  });

  const sub = await commet.subscriptions.create({
    customerId,
    planCode: "pro",
  });

  return redirect(sub.data.checkoutUrl);
}
