Building a real-time app with Shopify? Let us review it.
Expert code review for real-time apps built with Shopify. We fix Shopify-specific security gaps, optimize performance, and handle deployment. From $19.
Common Shopify issues we find
Real problems from Shopify codebases we've reviewed.
Slow theme performance
AI-generated Liquid templates with too many nested loops, unoptimized images, render-blocking scripts, and missing lazy loading — increasing page load time and hurting conversion rates.
Broken checkout customizations
Custom checkout scripts or Shopify Functions that break the checkout flow for certain payment methods, shipping options, or edge cases like discount stacking.
Insecure custom app webhooks
Shopify app webhook endpoints without HMAC signature verification, allowing attackers to send fake order, payment, or customer data to your systems.
API rate limit violations
Custom integrations that hit Shopify's API rate limits by making too many requests without proper throttling, causing sync failures and data inconsistencies.
Real-time App challenges to solve
Key real-time app concerns that AI-generated code often misses.
Connection management and reconnection
WebSocket connections drop constantly — network switches, phone sleep, server deploys. AI tools open a connection but don't handle disconnection, reconnection, or missed messages during downtime. Users see stale data or lose messages without knowing it.
Message ordering and delivery guarantees
Messages must arrive in order and must not be lost. Network issues can deliver messages out of sequence or duplicate them. AI-generated real-time code has no message ordering, no deduplication, and no delivery confirmation — which means lost messages and confused users.
Conflict resolution in collaborative editing
When two users edit the same content simultaneously, whose changes win? AI tools implement 'last write wins,' which silently discards one user's work. Production collaboration needs operational transforms or CRDTs to merge concurrent edits correctly.
Scaling concurrent connections
Each WebSocket connection holds server resources. A single server can handle hundreds of connections, but thousands require load balancing with sticky sessions, a pub/sub layer (like Redis), and horizontal scaling. AI tools don't implement any of this.
What we check
Key areas we review for Shopify real-time app projects.
Connection lifecycle — reconnection logic, heartbeat, graceful degradation
Message delivery — ordering guarantees, deduplication, acknowledgments
Authentication — WebSocket connections verified, channel-level authorization
Scaling — connection pooling, pub/sub architecture, horizontal scaling readiness
