# Turborepo Setup Summary

This document summarizes the Turborepo configuration improvements made to the xtablo monorepo.

## Overview

The monorepo now has a clear, efficient Turborepo setup with:

- **Source-only packages** (`@xtablo/shared`, `@xtablo/ui`) - no build step needed
- **Smart caching** for all tasks (build, test, lint, typecheck)
- **Clear task dependencies** and parallel execution
- **Comprehensive documentation** for all workflows

## Key Changes

### 1. Turborepo Configuration (`turbo.json`)

**Improvements:**

- Added explicit `inputs` for better cache invalidation
- Removed unnecessary `^build` dependencies for `dev`, `typecheck`, and `test` tasks
- Added `outputLogs` configuration for cleaner output
- Added `test:watch` task for interactive testing

**Task Configuration:**

- `build`: Only apps build, packages are source-only
- `dev`: No dependencies, instant start with HMR
- `lint`, `format`, `typecheck`, `test`: Run independently without waiting for builds

### 2. Package Configuration

#### Shared Package (`packages/shared/package.json`)

- **Removed:** `build`, `dev`, `clean` scripts
- **Kept:** `lint`, `lint:fix`, `format`, `typecheck`
- **Exports:** Point directly to TypeScript source files in `src/`

#### UI Package (`packages/ui/package.json`)

- **Removed:** `build`, `dev`, `clean` scripts
- **Kept:** `lint`, `lint:fix`, `format`, `typecheck`
- **Exports:** Point directly to TypeScript source files in `src/`

#### TypeScript Configuration

- Removed `composite`, `incremental`, and `outDir` from package tsconfigs
- Packages don't output built files anymore

### 3. Root Scripts (`package.json`)

**Added:**

- `build:apps` - Build only applications
- `dev:main` - Run main app only
- `dev:external` - Run external app only
- `lint:fix` - Fix linting issues across all packages
- `test:watch` - Run tests in watch mode

**Removed:**

- `build:packages` - No longer needed
- `clean:packages` - No longer needed

### 4. App Scripts

**Main App (`apps/main/package.json`):**

- Added `clean` script to remove build artifacts

**External App (`apps/external/package.json`):**

- Added `clean` script to remove build artifacts

### 5. Documentation

Created comprehensive documentation:

1. **DEVELOPMENT.md** (267 lines)
   - Complete development guide
   - Package development workflow
   - Troubleshooting section
   - CI/CD considerations

2. **TURBO_CHEATSHEET.md**
   - Quick reference for common commands
   - Turbo filter examples
   - Common workflows
   - Troubleshooting tips

3. **Updated README.md**
   - Simplified quick start
   - References to detailed documentation
   - Updated commands and structure

## Benefits

### Performance

- ⚡ **Faster dev startup**: No package build step required
- 🔥 **Instant HMR**: Vite hot-reloads package changes immediately
- 📦 **Smaller cache**: No package build artifacts to cache

### Developer Experience

- 🎯 **Simpler workflow**: Just `pnpm dev` to start
- 📚 **Clear documentation**: Three levels of docs (README, DEVELOPMENT, CHEATSHEET)
- 🧹 **Less complexity**: Fewer build steps to manage

### Maintainability

- 🔧 **Fewer moving parts**: Source-only packages are simpler
- 📝 **Better DX**: TypeScript types always in sync
- 🚀 **Future-proof**: Modern bundler-native approach

## Quick Commands

```bash
# Development
pnpm dev              # Start all apps
pnpm dev:main         # Start main app

# Build
pnpm build            # Build all apps
pnpm build:apps       # Same as above

# Quality
pnpm typecheck        # Type check everything
pnpm lint             # Lint everything
pnpm lint:fix         # Fix linting issues
pnpm test             # Run all tests
pnpm test:watch       # Run tests in watch mode

# Cleanup
pnpm clean            # Clean build artifacts
```

## Migration Notes

If you have existing `dist/` folders in packages:

```bash
rm -rf packages/*/dist packages/*/tsconfig.tsbuildinfo
```

No other migration is needed - packages now export source files directly.

## Next Steps

1. Run `pnpm install` to ensure workspace links are updated
2. Run `pnpm typecheck` to verify everything compiles
3. Run `pnpm dev` to start development
4. Read [DEVELOPMENT.md](./DEVELOPMENT.md) for detailed workflows
