Cheap, Simple Webhook Task Processing for Node.js SaaS
Short answer: for a Node.js SaaS that sends a weekly digest to active logistics customers, start with a durable queue, an explicit rate limiter, idempotent delivery records, and bounded exponential backoff; choose the cheapest simple option only after it can prove those delivery guarantees. I have been paged by missed jobs and duplicate deliveries. The failure pattern is predictable: a timer…
To build a reliable webhook task processing system for a Node.js SaaS, begin with a durable queue, a rate limiter, idempotent delivery records, and controlled retries. Do not rush to implement cheap solutions; ensure they meet the necessary delivery guarantees first. The author has experienced missed jobs and duplicate deliveries firsthand.
The root cause is predictable: a timer fires, a webhook is sent, the process crashes before logging the result, and the next retry sends the same business event again. Similarly, ignoring the recipient's rate limits can turn a minor outage into a queue storm, delaying deliveries for all customers.
