Beyond Build Orchestration: What It Takes to Build Modern JavaScript Monorepos
summary
Nx is a monorepo platform that couples task orchestration with developer UX: a terminal UI that visualizes targets and pins outputs, deep editor plugins that read project graphs and infer Vite/Jest targets, and metadata-fed JSON for editor and AI-agent integrations so agents get a map instead of raw files. Demo shows automatic output-folder caching, per-test granularity, and CI spread across three machines to finish a simple PR in minutes; a failing test is detected and fixed in-flight, proving the pipeline works end-to-end.
