## Description

Turborepo monorepo build system guidance. Triggers on: turbo.json, task pipelines, dependsOn, caching, remote cache, the "turbo" CLI, --filter, --affected, CI optimization, environment variables, internal packages, monorepo structure/best practices, and boundaries. Use when user: configures tasks/workflows/pipelines, creates packages, sets up monorepo, shares code between apps, runs changed/affected packages, debugs cache, or has apps/packages directories.

# Turborepo Skill

Build system for JavaScript/TypeScript monorepos. Turborepo caches task outputs and runs tasks in parallel based on dependency graph.

## IMPORTANT: Package Tasks, Not Root Tasks

**Prefer package tasks over Root Tasks.**

When creating tasks/scripts/pipelines, you MUST default to package tasks:

1. Add the script to each relevant package's `package.json`
2. Register the task in root `turbo.json`
3. Root `package.json` only delegates via `turbo run <task>`

**DO NOT** put task logic in root `package.json` when it can live in packages. This defeats Turborepo's parallelization.

```json
// DO THIS: Scripts in each package
// apps/web/package.json
{ "scripts": { "build": "next build", "lint": "eslint .", "test": "vitest" } }

// apps/api/package.json
{ "scripts": { "build": "tsc", "lint": "eslint .", "test": "vitest" } }

// packages/ui/package.json
{ "scripts": { "build": "tsc", "lint": "eslint .", "test": "vitest" } }
```

```json
// turbo.json - register tasks
{
  "tasks": {
    "build": { "dependsOn": ["^build"], "outputs": ["dist/**"] },
    "lint": {},
    "test": { "dependsOn": ["build"] }
  }
}
```

```json
// Root package.json - ONLY delegates, no task logic
{
  "scripts": {
    "build": "turbo run build",
    "lint": "turbo run lint",
    "test": "turbo run test"
  }
}
```

```json
// DO NOT DO THIS - defeats parallelization
// Root package.json
{
  "scripts": {
    "build": "cd apps/web && next build && cd ../api && tsc",
    "lint": "eslint apps/ packages/",
    "test": "vitest"
  }
}
```

Root Tasks (`//#taskname`) are ONLY for tasks that truly cannot exist in packages, such as Vitest Projects' `//#test`, repo-wide release scripts, or tooling that does not invoke `turbo` itself.

## Secondary Rule: `turbo run` vs `turbo`

**Always use `turbo run` when the command is written into code:**

```json
// package.json - ALWAYS "turbo run"
{
  "scripts": {
    "build": "turbo run build"
  }
}
```
