Interactive System Blueprints

Real production topologies engineered for zero data loss, sub-50ms database lookups, and resilient failover. Click any pipeline component below to inspect latency budgets, failure strategies, and implementation code.

TOPOLOGY FLOW ARCHITECTUREClick any node below to inspect production latency & source code

Engineered to ingest unpredictable bursts of WhatsApp webhook payloads, immediately respond with 200 OK to prevent Meta retries, and asynchronously process state transitions through Redis and BullMQ.

Meta Webhook → Next.js Edge Router → BullMQ Redis Buffer → Node.js State Worker → PostgreSQL Audit Ledger
SELECT PIPELINE COMPONENT:
NODE INSPECTION // Next.js Edge Ingest Router
Edge Runtime / Crypto API
LATENCY BUDGET< 35 ms
THROUGHPUT CAPACITY1,000+ req/s
RESPONSIBILITY & EXECUTION:

Verifies HMAC SHA-256 signatures, validates JSON shapes via Zod, and pushes job payloads directly to Redis.

FAILURE MODE & RECOVERY:

Immediately responds with HTTP 200 OK as soon as job is enqueued, protecting against timeouts.

PRODUCTION PATTERN SNIPPET:
// Non-blocking immediate queue injection
await messageQueue.add("process-whatsapp-event", {
  payload,
  receivedAt: Date.now(),
  idempotencyKey: payload.entry[0].changes[0].value.messages?.[0]?.id,
}, {
  attempts: 5,
  backoff: { type: "exponential", delay: 1000 },
  removeOnComplete: true,
});
return new Response("EVENT_RECEIVED", { status: 200 });
