Nx Monorepo

This handles the full lifecycle of Nx monorepo management, from workspace creation through CI/CD setup. You'll reach for it when generating apps and libraries, running affected commands to test only what changed, or setting up Module Federation for micro-frontends. It covers React, Next.js, and NestJS project types with practical commands for each. The skill shines in its affected command workflows and dependency graph debugging, which is honestly where most teams struggle with Nx. It assumes you're on Node 18.10+ and pushes you toward sensible patterns like organizing libs by domain rather than technical layer. Good reference for both greenfield setups and troubleshooting why your builds are slower than they should be.
