stripe-kit-hook

Simple and elegant abstraction to typesafely handle Stripe webhooks in SvelteKit. Also add a success callback in conjonction with and idempotency store to prevent duplicate processing. It's ain't much, but it works.

import { stripeWebhooks } from 'stripe-kit-hook';
import { sequence } from '@sveltejs/kit/hooks';
import { PRIVATE_STRIPE_SECRET_KEY, PRIVATE_STRIPE_WEBHOOK_SECRET } from '$env/static/private';

export const handle = sequence(
    async ({ event, resolve }) => {
        // run other hooks
        return resolve(event);
    },
    stripeWebhooks({
        secret: PRIVATE_STRIPE_SECRET_KEY,
        webhookSecret: PRIVATE_STRIPE_WEBHOOK_SECRET,
        // Use a fast KV store like Redis, Cloudflare KV, Upstash, etc.
        idempotencyStore: {
            get: async ({ key }) => {
                // Return true if already processed
            },
            set: async ({ key, value }) => {
                // Set the value to true when processed
            }
        },
        handlers: {
            'customer.created': ({ event, data, success }) => {
                console.log('customer.created', data);
                // Call success when done in order to store the idempotency key and prevent duplicate processing
                await success();
            }
        }
    })
);
