git sparse-checkout set services/auth packages/sharedNote Only checks out specified directories from a large repo. Extremely useful for monorepos where you only need a small portion. --filter=blob:none avoids downloading file content you don't need.

// Build with: tsc --build// tsc --build only recompiles packages that changedNote Project references enable incremental builds in monorepos. Each sub-project needs "composite": true. Build with tsc --build (or tsc -b) which understands dependency order. This dramatically speeds up type-checking in large codebases by skipping unchanged packages.
