backend-patterns
Provides backend architecture patterns, API design, database optimization, and server-side best practices for Node.js, Express, and Next.js applications.
What it does
Backend architecture patterns, API design, database optimization, and server-side best practices for Node.js, Express, and Next.js API routes. Use when building or reviewing Node.js, Express, or Next.js API routes and their data access.
Quality judgment
Well-organized, comprehensive coverage of API design, repository/service layers, caching, error handling, auth, rate limiting, and queues with clear PASS/FAIL code examples. Triggers are specific and actionable. Minor gaps: no mention of in-memory queue/limiter limitations in serverless environments, and some examples are domain-specific (markets/Supabase) rather than generic.
