turbo run Flags Reference

Full docs: https://turborepo.dev/docs/reference/run

Package Selection

--filter / -F

Select specific packages to run tasks in.

turbo build --filter=web
turbo build -F=@repo/ui -F=@repo/utils
turbo test --filter=./apps/*

See filtering/ for complete syntax (globs, dependencies, git ranges).

Task Identifier Syntax (v2.2.4+)

Run specific package tasks directly:

turbo run web#build              # Build web package
turbo run web#build docs#lint    # Multiple specific tasks

--affected

Run only in packages changed since the base branch.

turbo build --affected
turbo test --affected --filter=./apps/*  # combine with filter

How it works:

• Default: compares main...HEAD
• In GitHub Actions: auto-detects GITHUB_BASE_REF
• Override base: TURBO_SCM_BASE=development turbo build --affected
• Override head: TURBO_SCM_HEAD=your-branch turbo build --affected

Requires git history - shallow clones may fall back to running all tasks.

Execution Control

--dry / --dry=json

Preview what would run without executing.

turbo build --dry          # human-readable
turbo build --dry=json     # machine-readable

--force

Ignore all cached artifacts, re-run everything.

turbo build --force

--concurrency

Limit parallel task execution.

turbo build --concurrency=4      # max 4 tasks
turbo build --concurrency=50%    # 50% of CPU cores

--continue

Keep running other tasks when one fails.

turbo build test --continue

--only

Run only the specified task, skip its dependencies.

turbo build --only  # skip running dependsOn tasks

--parallel (Discouraged)

Ignores task graph dependencies, runs all tasks simultaneously. Avoid using this flag—if tasks need to run in parallel, configure dependsOn correctly instead. Using --parallel bypasses Turborepo's dependency graph, which can cause race conditions and incorrect builds.

Cache Control

--cache

Fine-grained cache behavior control.

# Default: read/write both local and remote
turbo build --cache=local:rw,remote:rw

# Read-only local, no remote
turbo build --cache=local:r,remote:

# Disable local, read-only remote
turbo build --cache=local:,remote:r

# Disable all caching
turbo build --cache=local:,remote:

Output & Debugging

--graph

Generate task graph visualization.

turbo build --graph                # opens in browser
turbo build --graph=graph.svg      # SVG file
turbo build --graph=graph.png      # PNG file
turbo build --graph=graph.json     # JSON data
turbo build --graph=graph.mermaid  # Mermaid diagram

--summarize

Generate JSON run summary for debugging.

turbo build --summarize
# creates .turbo/runs/<run-id>.json

--output-logs

Control log output verbosity.

turbo build --output-logs=full        # all logs (default)
turbo build --output-logs=new-only    # only cache misses
turbo build --output-logs=errors-only # only failures
turbo build --output-logs=none        # silent

--profile

Generate Chrome tracing profile for performance analysis.

turbo build --profile=profile.json
# open chrome://tracing and load the file

--verbosity / -v

Control turbo's own log level.

turbo build -v      # verbose
turbo build -vv     # more verbose
turbo build -vvv    # maximum verbosity

Environment

--env-mode

Control environment variable handling.

turbo build --env-mode=strict  # only declared env vars (default)
turbo build --env-mode=loose   # include all env vars in hash

UI

--ui

Select output interface.

turbo build --ui=tui     # interactive terminal UI (default in TTY)
turbo build --ui=stream  # streaming logs (default in CI)

turbo-ignore

Full docs: https://turborepo.dev/docs/reference/turbo-ignore

Skip CI work when nothing relevant changed. Useful for skipping container setup.

Basic Usage

# Check if build is needed for current package (uses Automatic Package Scoping)
npx turbo-ignore

# Check specific package
npx turbo-ignore web

# Check specific task
npx turbo-ignore --task=test

Exit Codes

• 0: No changes detected - skip CI work
• 1: Changes detected - proceed with CI

CI Integration Example

# GitHub Actions
- name: Check for changes
  id: turbo-ignore
  run: npx turbo-ignore web
  continue-on-error: true

- name: Build
  if: steps.turbo-ignore.outcome == 'failure'  # changes detected
  run: pnpm build

Comparison Depth

Default: compares to parent commit (HEAD^1).

# Compare to specific commit
npx turbo-ignore --fallback=abc123

# Compare to branch
npx turbo-ignore --fallback=main
