SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Headless VTEX storefronts often struggle to balance performance and data freshness. Without a clear caching strategy, API calls hit origin services too frequently, leading to increased latency, higher costs, and potential rate-limit issues.

Core Features & Use Cases

Classify VTEX API responses by cacheability to drive TTLs and invalidation.
Define appropriate TTLs and stale-while-revalidate (SWR) patterns for CDN, BFF, and edge caches.
Provide an invalidation framework using webhooks, events, and manual purges to keep data fresh.
Guide architecture decisions that separate cacheable public data from non-cacheable transactional data.

Quick Start

Configure CDN edge caching and a BFF cache with TTLs and event-driven invalidation for a headless VTEX storefront.

FAQPage Schema

What is a caching strategy for headless VTEX storefronts?▼

A headless VTEX caching strategy classifies API responses by cacheability to assign TTLs and invalidation rules, separating public data cached at the CDN edge and BFF from fresh transactional endpoints.

Why does my headless storefront hit VTEX API rate limits?▼

Headless storefronts hit VTEX API rate limits when lacking a defined caching strategy, causing calls to hit origin services too frequently and increasing latency, costs, and rate-limit issues.

How do I configure stale-while-revalidate for a VTEX BFF cache?▼

Configure stale-while-revalidate in your VTEX BFF cache by classifying API responses, defining TTL ranges for cacheable public data, and serving stale content while asynchronously revalidating from the origin.

What's the best way to invalidate cached data in a headless VTEX app?▼

The best way to invalidate cached data in a headless VTEX app is an event-driven framework using webhooks, events, and manual purges to ensure non-cacheable endpoints remain fresh.

Can I cache transactional VTEX API responses at the CDN edge?▼

Transactional VTEX API responses are non-cacheable and should remain fresh by bypassing CDN edge caching, reserving edge cache storage for cacheable public data with defined TTL ranges.

Do I need a BFF to separate cacheable and non-cacheable VTEX data?▼

A BFF is needed to separate cacheable public data from non-cacheable transactional VTEX data, guiding architecture decisions that apply appropriate TTLs and stale-while-revalidate patterns across edge caches.
