skillboardNavigate, manage, and optimize monorepos. Covers Turborepo, Nx, pnpm workspaces, and Lerna. Cross-package impact analysis, selective builds/tests on affected packages, remote caching, dependency graph visualization, and structured multi-repo to monorepo migrations. Use when setting up a new monorepo, optimizing CI for a large workspace, debugging cross-package dependency issues, or planning a multi-repo consolidation.

Navigate, manage, and optimize monorepos. Covers Turborepo, Nx, pnpm workspaces, and Lerna. Enables cross-package impact analysis, selective builds/tests on affected packages only, remote caching, dependency graph visualization, and structured migrations from multi-repo to monorepo. Includes Claude Code configuration for workspace-aware development.
Use when:
Skip when:
| Tool | Best For | Key Feature |
|---|---|---|
| Turborepo | JS/TS monorepos, simple pipeline config | Best-in-class remote caching, minimal config |
| Nx | Large enterprises, plugin ecosystem | Project graph, code generation, affected commands |
| pnpm workspaces | Workspace protocol, disk efficiency | workspace:* for local package refs |
| Lerna | npm publishing, versioning | Batch publishing, conventional commits |
| Changesets | Modern versioning (preferred over Lerna) | Changelog generation, pre-release channels |
Most modern setups: pnpm workspaces + Turborepo + Changesets

| Pitfall | Fix |
|---|---|
| Running turbo run build without --filter on every PR | Always use --filter=...[origin/main] in CI |
| workspace:* refs cause publish failures | Use pnpm changeset publish — it replaces workspace:* with real versions automatically |
| All packages rebuild when unrelated file changes | Tune inputs in turbo.json to exclude docs, config files from cache keys |
| Shared tsconfig causes one package to break all type-checks | Use extends properly — each package extends root but overrides rootDir / outDir |
| git history lost during migration | Use git filter-repo --to-subdirectory-filter before merging — never move files manually |
| Remote cache not working in CI | Check TURBO_TOKEN and TURBO_TEAM env vars; verify with turbo run build --summarize |
| CLAUDE.md too generic — Claude modifies wrong package | Add explicit "When working on X, only touch files in apps/X" rules per package CLAUDE.md |
