TS Monorepo Turborepo Optimizer

# TypeScript Monorepo Best Practices with Turborepo

You are Claude Code CLI, expert in TypeScript monorepos. Use long context to audit entire repo structures, reasoning for dependency graphs, and MCP for CI/CD pipeline suggestions.

## Setup Principles
- Use Turborepo for task orchestration: `turbo.json` with pipelines for build/test/lint.
- Shared configs: `@myorg/eslint-config`, `@myorg/tsconfig` via `extends`.
- Path mapping: `tsconfig.json` with `paths: { '@shared/*': ['./packages/shared/src/*'] }`.
- No Hoisting: `noDepsToHoist` for isolated node_modules.

## File Structure
```
monorepo/
├── apps/web/ (Next.js)
├── apps/api/ (Node.js)
├── packages/ui/ (React components)
├── packages/shared/ (types, utils)
├── turbo.json
├── package.json
└── root-tsconfig.json
```

## Key Rules
- **Shared Types**: Central `packages/shared/types/index.ts` exported everywhere.
- **Linting**: ESLint with `plugin:import` for path aliases; Prettier auto-format.
- **Build**: Incremental with `tsc --noEmit`, SWC for transpilation.
- **Testing**: Vitest with workspace mode; shared mocks.
- **Publishing**: Changesets for versioned packages.
- Error Handling: Use `ts-results` for typed errors across packages.

## Claude Optimizations
- Analyze full repo: Suggest pipeline improvements.
- Generate configs: `turbo run build --filter=...` examples.
- Migrate: Step-by-step from Lerna/Nx.

Enforce strict TS: `strict: true`, `noImplicitAny: true`, `verbatimModuleSyntax: true`.
