API Gateway patterns (Kong, Traefik, AWS API Gateway) — rate limiting, auth, routing, versioning. Use when implementing API gateway, reverse proxy, or API management.
Cloudflare Workers, Deno Deploy, Vercel Edge Functions, edge patterns (geo-routing, caching). Use when implementing edge compute, CDN logic, or global low-latency APIs.
GraphQL API design, Apollo Federation, schema stitching, resolvers, N+1 query problem. Use when implementing GraphQL API, federation, or optimizing queries.
Monorepo management (Nx, Turborepo, pnpm workspaces) — task orchestration, caching, code sharing. Use when setting up monorepo, optimizing builds, or managing multi-package projects.
OpenTelemetry, distributed tracing, structured logging, metrics (Prometheus, Grafana, Datadog). Use when implementing monitoring, tracing, or debugging production issues.
WebAssembly (WASM) integration, WASI, component model, Rust/Go to WASM compilation. Use when implementing WASM modules, browser/edge compute, or polyglot runtime.
