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:

Add the script to each relevant package's package.json
Register the task in root turbo.json
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"
  }
}

yaml

# CI workflows - ALWAYS "turbo run"
- run: turbo run build --affected

The shorthand turbo <tasks> is ONLY for one-off terminal commands typed directly by humans or agents. Never write turbo build into package.json, CI, or scripts.

Critical Anti-Patterns

Using `turbo` Shorthand in Code

turbo run is recommended in package.json scripts and CI pipelines. The shorthand turbo <task> is intended for interactive terminal use.

json

// WRONG - using shorthand in package.json
{
  "scripts": {
    "build": "turbo build",
    "dev": "turbo dev"
  }
}

// CORRECT
{
  "scripts": {
    "build": "turbo run build",
    "dev": "turbo run dev"
  }
}

yaml

# WRONG - using shorthand in CI
- run: turbo build --affected

# CORRECT
- run: turbo run build --affected

Root Scripts Bypassing Turbo

Root package.json scripts MUST delegate to turbo run, not run tasks directly.

json

// WRONG - bypasses turbo entirely
{
  "scripts": {
    "build": "bun build",
    "dev": "bun dev"
  }
}

// CORRECT - delegates to turbo
{
  "scripts": {
    "build": "turbo run build",
    "dev": "turbo run dev"
  }
}

Using `&&` to Chain Turbo Tasks

Don't chain turbo tasks with &&. Let turbo orchestrate.

json

// WRONG - turbo task not using turbo run
{
  "scripts": {
    "changeset:publish": "bun build && changeset publish"
  }
}

// CORRECT
{
  "scripts": {
    "changeset:publish": "turbo run build && changeset publish"
  }
}

`prebuild` Scripts That Manually Build Dependencies

Scripts like prebuild that manually build other packages bypass Turborepo's dependency graph.

json

// WRONG - manually building dependencies
{
  "scripts": {
    "prebuild": "cd ../../packages/types && bun run build && cd ../utils && bun run build",
    "build": "next build"
  }
}

However, the fix depends on whether workspace dependencies are declared:

If dependencies ARE declared (e.g., "@repo/types": "workspace:*" in package.json), remove the prebuild script. Turbo's dependsOn: ["^build"] handles this automatically.
If dependencies are NOT declared, the prebuild exists because ^build won't trigger without a dependency relationship. The fix is to:
- Add the dependency to package.json: "@repo/types": "workspace:*"
- Then remove the prebuild script

json

// CORRECT - declare dependency, let turbo handle build order
// package.json
{
  "dependencies": {
    "@repo/types": "workspace:*",
    "@repo/utils": "workspace:*"
  },
  "scripts": {
    "build": "next build"
  }
}

// turbo.json
{
  "tasks": {
    "build": {
      "dependsOn": ["^build"]
    }
  }
}

Key insight: ^build only runs build in packages listed as dependencies. No dependency declaration = no automatic build ordering.

Overly Broad `globalDependencies`

globalDependencies affects ALL tasks in ALL packages via the global hash — tasks cannot opt out of specific files, even with negation globs in inputs. Be specific.

json

// WRONG - heavy hammer, affects all hashes
{
  "globalDependencies": ["**/.env.*local"]
}

// BETTER - move to task-level inputs
{
  "globalDependencies": [".env"],
  "tasks": {
    "build": {
      "inputs": ["$TURBO_DEFAULT$", ".env*"],
      "outputs": ["dist/**"]
    }
  }
}

With futureFlags.globalConfiguration, this problem is reduced because global.inputs files are folded into each task's inputs (not the global hash). Tasks can exclude specific files:

json

// BEST - global.inputs with per-task exclusion
{
  "futureFlags": { "globalConfiguration": true },
  "global": {
    "inputs": [".env"]
  },
  "tasks": {
    "build": { "outputs": ["dist/**"] },
    "lint": {
      "inputs": ["$TURBO_DEFAULT$", "!$TURBO_ROOT$/.env"]
    }
  }
}

Repetitive Task Configuration

Look for repeated configuration across tasks that can be collapsed. Turborepo supports shared configuration patterns.

json

// WRONG - repetitive env and inputs across tasks
{
  "tasks": {
    "build": {
      "env": ["API_URL", "DATABASE_URL"],
      "inputs": ["$TURBO_DEFAULT$", ".env*"]
    },
    "test": {
      "env": ["API_URL", "DATABASE_URL"],
      "inputs": ["$TURBO_DEFAULT$", ".env*"]
    },
    "dev": {
      "env": ["API_URL", "DATABASE_URL"],
      "inputs": ["$TURBO_DEFAULT$", ".env*"],
      "cache": false,
      "persistent": true
    }
  }
}

// BETTER - use globalEnv and globalDependencies for shared config
{
  "globalEnv": ["API_URL", "DATABASE_URL"],
  "globalDependencies": [".env*"],
  "tasks": {
    "build": {},
    "test": {},
    "dev": {
      "cache": false,
      "persistent": true
    }
  }
}

When to use global vs task-level:

globalEnv / globalDependencies - affects ALL tasks, use for truly shared config
Task-level env / inputs - use when only specific tasks need it

NOT an Anti-Pattern: Large `env` Arrays

A large env array (even 50+ variables) is not a problem. It usually means the user was thorough about declaring their build's environment dependencies. Do not flag this as an issue.

Using `--parallel` Flag

The --parallel flag bypasses Turborepo's dependency graph. If tasks need parallel execution, configure dependsOn correctly instead.

bash

# WRONG - bypasses dependency graph
turbo run lint --parallel

# CORRECT - configure tasks to allow parallel execution
# In turbo.json, set dependsOn appropriately (or use transit nodes)
turbo run lint

Package-Specific Task Overrides in Root turbo.json

When multiple packages need different task configurations, use Package Configurations (turbo.json in each package) instead of cluttering root turbo.json with package#task overrides.

json

// WRONG - root turbo.json with many package-specific overrides
{
  "tasks": {
    "test": { "dependsOn": ["build"] },
    "@repo/web#test": { "outputs": ["coverage/**"] },
    "@repo/api#test": { "outputs": ["coverage/**"] },
    "@repo/utils#test": { "outputs": [] },
    "@repo/cli#test": { "outputs": [] },
    "@repo/core#test": { "outputs": [] }
  }
}

// CORRECT - use Package Configurations
// Root turbo.json - base config only
{
  "tasks": {
    "test": { "dependsOn": ["build"] }
  }
}

// packages/web/turbo.json - package-specific override
{
  "extends": ["//"],
  "tasks": {
    "test": { "outputs": ["coverage/**"] }
  }
}

// packages/api/turbo.json
{
  "extends": ["//"],
  "tasks": {
    "test": { "outputs": ["coverage/**"] }
  }
}

Benefits of Package Configurations:

Keeps configuration close to the code it affects
Root turbo.json stays clean and focused on base patterns
Easier to understand what's special about each package
Works with $TURBO_EXTENDS$ to inherit + extend arrays

When to use package#task in root:

Single package needs a unique dependency (e.g., "deploy": { "dependsOn": ["web#build"] })
Temporary override while migrating

See references/configuration/RULE.md#package-configurations for full details.

Using `../` to Traverse Out of Package in `inputs`

Don't use relative paths like ../ to reference files outside the package. Use $TURBO_ROOT$ instead.

json

// WRONG - traversing out of package
{
  "tasks": {
    "build": {
      "inputs": ["$TURBO_DEFAULT$", "../shared-config.json"]
    }
  }
}

// CORRECT - use $TURBO_ROOT$ for repo root
{
  "tasks": {
    "build": {
      "inputs": ["$TURBO_DEFAULT$", "$TURBO_ROOT$/shared-config.json"]
    }
  }
}

Missing `outputs` for File-Producing Tasks

Before flagging missing outputs, check what the task actually produces:

Read the package's script (e.g., "build": "tsc", "test": "vitest")
Determine if it writes files to disk or only outputs to stdout
Only flag if the task produces files that should be cached

json

// WRONG: build produces files but they're not cached
{
  "tasks": {
    "build": {
      "dependsOn": ["^build"]
    }
  }
}

// CORRECT: build outputs are cached
{
  "tasks": {
    "build": {
      "dependsOn": ["^build"],
      "outputs": ["dist/**"]
    }
  }
}

Common outputs by framework:

Next.js: [".next/**", "!.next/cache/**", "!.next/dev/**"]
Vite/Rollup: ["dist/**"]
tsc: ["dist/**"] or custom outDir

TypeScript --noEmit can still produce cache files:

When incremental: true in tsconfig.json, tsc --noEmit writes .tsbuildinfo files even without emitting JS. Check the tsconfig before assuming no outputs:

json

// If tsconfig has incremental: true, tsc --noEmit produces cache files
{
  "tasks": {
    "typecheck": {
      "outputs": ["node_modules/.cache/tsbuildinfo.json"] // or wherever tsBuildInfoFile points
    }
  }
}

To determine correct outputs for TypeScript tasks:

Check if incremental or composite is enabled in tsconfig
Check tsBuildInfoFile for custom cache location (default: alongside outDir or in project root)
If no incremental mode, tsc --noEmit produces no files

`^build` vs `build` Confusion

json

{
  "tasks": {
    // ^build = run build in DEPENDENCIES first (other packages this one imports)
    "build": {
      "dependsOn": ["^build"]
    },
    // build (no ^) = run build in SAME PACKAGE first
    "test": {
      "dependsOn": ["build"]
    },
    // pkg#task = specific package's task
    "deploy": {
      "dependsOn": ["web#build"]
    }
  }
}

Environment Variables Not Hashed

json

// WRONG: API_URL changes won't cause rebuilds
{
  "tasks": {
    "build": {
      "outputs": ["dist/**"]
    }
  }
}

// CORRECT: API_URL changes invalidate cache
{
  "tasks": {
    "build": {
      "outputs": ["dist/**"],
      "env": ["API_URL", "API_KEY"]
    }
  }
}

`.env` Files Not in Inputs

Turbo does NOT load .env files - your framework does. But Turbo needs to know about changes:

json

// WRONG: .env changes don't invalidate cache
{
  "tasks": {
    "build": {
      "env": ["API_URL"]
    }
  }
}

// CORRECT: .env file changes invalidate cache
{
  "tasks": {
    "build": {
      "env": ["API_URL"],
      "inputs": ["$TURBO_DEFAULT$", ".env", ".env.*"]
    }
  }
}

Root `.env` File in Monorepo

A .env file at the repo root is an anti-pattern — even for small monorepos or starter templates. It creates implicit coupling between packages and makes it unclear which packages depend on which variables.

text

// WRONG - root .env affects all packages implicitly
my-monorepo/
├── .env              # Which packages use this?
├── apps/
│   ├── web/
│   └── api/
└── packages/

// CORRECT - .env files in packages that need them
my-monorepo/
├── apps/
│   ├── web/
│   │   └── .env      # Clear: web needs DATABASE_URL
│   └── api/
│       └── .env      # Clear: api needs API_KEY
└── packages/

Problems with root .env:

Unclear which packages consume which variables
All packages get all variables (even ones they don't need)
Cache invalidation is coarse-grained (root .env change invalidates everything)
Security risk: packages may accidentally access sensitive vars meant for others
Bad habits start small — starter templates should model correct patterns

If you must share variables, use globalEnv to be explicit about what's shared, and document why.

Strict Mode Filtering CI Variables

By default, Turborepo filters environment variables to only those in env/globalEnv. CI variables may be missing:

json

// If CI scripts need GITHUB_TOKEN but it's not in env:
{
  "globalPassThroughEnv": ["GITHUB_TOKEN", "CI"],
  "tasks": { ... }
}

Or use --env-mode=loose (not recommended for production).

Shared Code in Apps (Should Be a Package)

text

// WRONG: Shared code inside an app
apps/
  web/
    shared/          # This breaks monorepo principles!
      utils.ts

// CORRECT: Extract to a package
packages/
  utils/
    src/utils.ts

Accessing Files Across Package Boundaries

typescript

// WRONG: Reaching into another package's internals
import { Button } from "../../packages/ui/src/button";

// CORRECT: Install and import properly
import { Button } from "@repo/ui/button";

Too Many Root Dependencies

json

// WRONG: App dependencies in root
{
  "dependencies": {
    "react": "^18",
    "next": "^14"
  }
}

// CORRECT: Only repo tools in root
{
  "devDependencies": {
    "turbo": "latest"
  }
}

Common Task Configurations

Standard Build Pipeline

json

{
  "$schema": "https://v2-9-19-canary-9.turborepo.dev/schema.json",
  "tasks": {
    "build": {
      "dependsOn": ["^build"],
      "outputs": ["dist/**", ".next/**", "!.next/cache/**", "!.next/dev/**"]
    },
    "dev": {
      "cache": false,
      "persistent": true
    }
  }
}

Add a transit task if you have tasks that need parallel execution with cache invalidation (see below).

Dev Task with `^dev` Pattern (for `turbo watch`)

A dev task with dependsOn: ["^dev"] and persistent: false in root turbo.json may look unusual but is correct for turbo watch workflows:

json

// Root turbo.json
{
  "tasks": {
    "dev": {
      "dependsOn": ["^dev"],
      "cache": false,
      "persistent": false  // Packages have one-shot dev scripts
    }
  }
}

// Package turbo.json (apps/web/turbo.json)
{
  "extends": ["//"],
  "tasks": {
    "dev": {
      "persistent": true  // Apps run long-running dev servers
    }
  }
}

Why this works:

Packages (e.g., @acme/db, @acme/validators) have "dev": "tsc" — one-shot type generation that completes quickly
Apps override with persistent: true for actual dev servers (Next.js, etc.)
turbo watch re-runs the one-shot package dev scripts when source files change, keeping types in sync

Intended usage: Run turbo watch dev (not turbo run dev). Watch mode re-executes one-shot tasks on file changes while keeping persistent tasks running.

Alternative pattern: Use a separate task name like prepare or generate for one-shot dependency builds to make the intent clearer:

json

{
  "tasks": {
    "prepare": {
      "dependsOn": ["^prepare"],
      "outputs": ["dist/**"]
    },
    "dev": {
      "dependsOn": ["prepare"],
      "cache": false,
      "persistent": true
    }
  }
}

Transit Nodes for Parallel Tasks with Cache Invalidation

Some tasks can run in parallel (don't need built output from dependencies) but must invalidate cache when dependency source code changes.

The problem with dependsOn: ["^taskname"]:

Forces sequential execution (slow)

The problem with dependsOn: [] (no dependencies):

Allows parallel execution (fast)
But cache is INCORRECT - changing dependency source won't invalidate cache

Transit Nodes solve both:

json

{
  "tasks": {
    "transit": { "dependsOn": ["^transit"] },
    "my-task": { "dependsOn": ["transit"] }
  }
}

The transit task creates dependency relationships without matching any actual script, so tasks run in parallel with correct cache invalidation.

How to identify tasks that need this pattern: Look for tasks that read source files from dependencies but don't need their build outputs.

With Environment Variables

json

{
  "globalEnv": ["NODE_ENV"],
  "globalDependencies": [".env"],
  "tasks": {
    "build": {
      "dependsOn": ["^build"],
      "outputs": ["dist/**"],
      "env": ["API_URL", "DATABASE_URL"]
    }
  }
}

With futureFlags.globalConfiguration, the same config moves global settings under global — and .env becomes a per-task input instead of a global hash input:

json

{
  "futureFlags": { "globalConfiguration": true },
  "global": {
    "env": ["NODE_ENV"],
    "inputs": [".env"]
  },
  "tasks": {
    "build": {
      "dependsOn": ["^build"],
      "outputs": ["dist/**"],
      "env": ["API_URL", "DATABASE_URL"]
    }
  }
}
