DeadCode

Detect and remove unused exports, dead routes, orphaned CSS, and unreferenced components in TypeScript/React/Next.js projects.

⭐ Star this repo if you care about bundle size — it helps other devs find DeadCode!

Commands

deadcode scan

Scan a TypeScript/React/Next.js project for all categories of dead code.

deadcode scan                          # Scan current directory
deadcode scan -p /path/to/project      # Scan specific project
deadcode scan --json-output            # Machine-readable JSON
deadcode scan -c unused_export         # Filter by category
deadcode scan -i "generated/"          # Ignore paths

deadcode remove

Remove dead code after previewing. Always preview with --dry-run first.

deadcode remove --dry-run              # Preview changes (no writes)
deadcode remove                        # Apply removals
deadcode remove -c orphaned_css        # Remove only orphaned CSS

deadcode stats

Quick overview of dead code in your project.

deadcode stats

Categories

| Category | Description | Example | |----------|-------------|---------| | unused_export | Exported names never imported elsewhere | export function oldHelper() with zero consumers | | dead_route | Next.js routes with no internal links | app/legacy/page.tsx no longer linked from navigation | | orphaned_css | CSS classes not referenced in JSX | .oldClass in styles.module.css with zero usages | | unreferenced_component | React components defined but never imported | A <LegacyWidget> component with no import sites |

Features

• Unused export detection — finds functions, types, classes, interfaces, enums, and consts that are exported but never imported within your project
• Dead route detection — detects unreachable page components in Next.js App Router projects
• Orphaned CSS detection — finds CSS module classes that are defined but never referenced in TSX/JSX files
• Safe auto-removal — --dry-run preview shows exactly what will be deleted first; remove only blanks self-contained single-line findings and skips (with a warning) anything spanning multiple lines, so it never leaves half-deleted, broken code
• Full-project scanning — fast regex-based scanning covers export/import patterns, route detection, CSS class usage, and component references across your entire codebase (no AST/tree-sitter — deliberately dependency-free and quick)
• Monorepo support — handles large projects efficiently with ignore patterns
• CI integration — JSON output for automated pipelines and gating

Ignore / Include Patterns

# Ignore specific paths
deadcode scan -i "generated/" -i "**/*.generated.ts"

# Include only matching paths (whitelist)
deadcode scan --include "src/"                          # Only scan src/
deadcode scan --include "src/" --include "lib/"          # Multiple dirs
deadcode remove --dry-run --include "packages/"          # Works with remove
deadcode stats --include "app/"                          # Works with stats

--include accepts gitignore-style patterns and is repeatable (specify multiple targets). When both --include and -i/--ignore are used, --include is applied first, then --ignore excludes any matches within the included paths.

Default ignores: node_modules/, .git/, .next/, dist/, build/, public/, static/

CI/CD Integration

# Generate report for CI
deadcode scan --json-output > deadcode-report.json

# Fail CI if any dead routes found
deadcode scan -c dead_route --fail 1

# Fail CI if total findings exceed threshold
deadcode scan --fail 10

# Track dead code trends over time
deadcode scan --json-output > baseline-$(date +%Y-%m-%d).json

Configuration (.deadcode.yml)

Create a .deadcode.yml file in your project root:

# .deadcode.yml
ignore:
  - "generated/"
  - "**/*.generated.ts"
  - "src/legacy/"

categories:
  - unused_export
  - dead_route
  - orphaned_css
  - unreferenced_component

# Exit with code 1 if findings >= this number (for CI gating)
fail_threshold: 10

CLI flags override config file settings.

Storage

• .deadcode.yml — project configuration (ignore patterns, categories)
• deadcode-baseline.json — saved scan results for trend tracking

Roadmap

• [ ] VS Code extension with inline decorations showing dead code
• [ ] ESLint plugin integration with auto-fix
• [ ] Webpack/Rollup bundle analysis hooks
• [ ] MCP server for AI-assisted cleanup
• [ ] Incremental scanning with cache
• [ ] GitHub Actions annotator for PR comments
