SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Vague "make it faster" requests often lead to accidental dynamic rendering, leaked personal data in shared caches, and edge runtime crashes from Node-only imports. This Skill turns those requests into deliberate, production-safe caching and rendering decisions. ## Core Features & Use Cases - Rendering Strategy Selection: Classify data by volatility, sensitivity, and audience specificity, then choose between static, ISR, PPR, dynamic, route handlers, and middleware. - Cache Layer Assignment: Assign the right cache layer (data cache, route cache, router cache, or CDN) with explicit invalidation events and cache tags. - Edge Compatibility Review: Verify that edge routes avoid Node-only APIs and that personalization stays separated from shared cacheable content. - Use Case: When building a Next.js storefront with personalized recommendations, use this Skill to design a static shell with dynamic islands, define cache tags for inventory updates, and keep user data out of the shared CDN cache. ## Quick Start Ask the AI to design a caching and rendering strategy for your Next.js page, describing your data sources, personalization needs, and latency budget.

Frequently Asked Questions about edge-cache-architecture-architect

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I choose between static, ISR, and dynamic rendering in Next.js?▼

Classify each data source by volatility, sensitivity, and audience specificity first. Use static rendering for stable shared content, ISR or stale-while-revalidate for content tolerating brief staleness, and dynamic rendering only for user-specific or rapidly changing data.

How to implement cache invalidation in Next.js with cache tags?▼

Assign explicit cache tags to data fetches that correspond to business events, then revalidate those tags when the events occur. Identify invalidation events before writing the implementation so every cached entry has a documented, testable invalidation path.

Can I use Node.js APIs in Next.js edge runtime middleware?▼

No, edge runtime code must stay free of Node-only APIs and assumptions. Verify every imported module for edge compatibility, and keep middleware limited to lightweight routing rather than heavy business logic.

Why does my Next.js app accidentally become fully dynamic?▼

A shared layout or root-level call that reads request-specific data can force the entire route tree into dynamic rendering. Audit layouts and root components so shared chrome stays cacheable while personalization lives in isolated dynamic islands.

How do I personalize content without breaking CDN caching?▼

Split expensive personalization from globally cacheable chrome using a static shell plus dynamic islands pattern. Ensure personal data never enters caches intended for shared content, and prefetch only where it meaningfully improves perceived speed.
