Shopify Load & Scale
Overview
Load test Shopify app integrations while respecting API rate limits. Plan capacity for high-traffic events like Black Friday / Cyber Monday (BFCM).
Prerequisites
- k6 load testing tool installed (
brew install k6)
- Test store with API access (never load test production)
- Understanding of Shopify rate limits per plan
Instructions
Step 1: Understand Capacity Constraints
Your app's throughput is bounded by Shopify's rate limits, not your infrastructure:
| Plan | GraphQL Points | Restore Rate | Max Sustained QPS | Burst Capacity |
|---|
| Standard | 1,000 | 50/sec | ~10 queries/sec | 1,000 points burst |
| Shopify Plus | 2,000 | 100/sec | ~20 queries/sec | 2,000 points burst |
A typical product query costs 10-50 points. At 50 points/query, Standard supports ~1 query/second sustained.
Step 2: k6 Load Test Script
k6 script with Shopify-specific custom metrics (throttle tracking, query cost trends, error rates) and automatic request pacing.
See k6 Load Test Script for the complete test script.
Step 3: Run Load Test
k6 run \
--env SHOPIFY_STORE=dev-store.myshopify.com \
--env SHOPIFY_ACCESS_TOKEN=shpat_test_token \
shopify-load-test.js
k6 run --out influxdb=http://localhost:8086/k6 shopify-load-test.js
Step 4: BFCM / Flash Sale Preparation
Pre-BFCM preparation including cache pre-warming, Storefront API offloading, bulk inventory sync, and Kubernetes HPA configuration for webhook processing.
See BFCM Preparation for application-level and infrastructure scaling patterns.
Output
- Load test script calibrated to Shopify rate limits
- Performance baseline documented
- BFCM preparation checklist completed
- Infrastructure scaling configured for webhook volume
