SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Cloudflare architecture patterns provide reusable, battle-tested solutions to common scaling and reliability challenges across Cloudflare Workers and edge deployments.

Core Features & Use Cases

Pattern Catalog: a curated set of patterns with symptoms, detection methods, and implementation steps.
Practical Guides: step-by-step instructions to apply patterns to typical workloads (D1 cost optimization, circuit breakers for external calls, service bindings, KV caching, R2 caching).
Real-world Examples: concrete scenarios mapping patterns to project structures and deployment choices.

Quick Start

Select a pattern from the catalog and implement its recommended steps in a sample Cloudflare Worker.

FAQPage Schema

What are Cloudflare architecture patterns and when do I need them?▼

Cloudflare architecture patterns are reusable solutions for scaling and reliability challenges across edge deployments. You need them to solve common Worker design problems like handling external API failures, reducing D1 write costs, or lowering subrequest limits.

How do I reduce D1 write costs in my Cloudflare Worker?▼

To reduce D1 write costs, select a cost optimization pattern from the catalog and follow its step-by-step implementation guide. The skill provides practical instructions to apply caching and architectural patterns specifically for typical D1 database workloads.

How do I handle external API failures in Cloudflare Workers?▼

Handle external API failures by implementing the circuit breaker pattern from the catalog. The skill provides concrete examples and step-by-step instructions to detect failure symptoms and apply resilience patterns across your edge deployments.

Can I use these architecture patterns to decompose a monolithic Cloudflare Worker?▼

Yes, you can decompose monolithic Workers by applying service binding patterns from the catalog. The skill maps real-world scenarios to project structures, guiding you through implementation steps to split workloads and reduce subrequest limits.

What's the best way to cache data using R2 and KV in Cloudflare edge computing?▼

The best way to cache data is by applying the R2 and KV caching patterns provided in the catalog. The skill offers practical guides with concrete examples to map caching patterns directly to your project structure and deployment choices.
