dep-scope

Symbol-level dependency analysis + LLM-ready migration prompts for TypeScript/JavaScript projects.

"Knip tells you what's unused. dep-scope tells you how you use what you keep, and generates the prompt to remove it."

When to use dep-scope

Good use cases:

• Legacy project audit: Finding lodash functions that now have native equivalents
• Library consolidation: Do we really need 3 icon libraries?
• Migration: Generate a context-aware prompt and let Claude Code do the refactoring
• Curiosity: "Which symbols from this 50KB library do we actually use?"

Not the right tool if:

• You just want unused deps → use Knip instead
• Your codebase is already well-maintained → dep-scope will mostly say "KEEP"

Quick Example

$ dep-scope scan

  dep-scope Analysis Report
═══════════════════════════════════════════

Summary:
  Total dependencies: 45
  ✓ Keep:          38
  ↻ Recode Native: 3
  ✗ Remove:        2
  ⊕ Peer Dep:      4

Action Items:
  Remove (unused):
    ✗ moment
    ✗ has-flag

  Recode to native:
    ↻ lodash.debounce (1 symbol) → custom debounce function
    ↻ array-includes (1 symbol) → Array.prototype.includes
    ↻ left-pad (1 symbol) → String.prototype.padStart

How it compares

Recommendation: Use Knip for unused detection, dep-scope for deeper analysis and migration. They work well together (dep-scope auto-detects Knip if installed).

Installation

CLI (global):

npm install -g @florianbruniaux/dep-scope

Without installation:

npx @florianbruniaux/dep-scope scan

MCP Server (AI editors — no CLI needed):

Add to your editor's MCP config and the server runs on demand via npx. See the MCP Server section below for per-editor config snippets.

From source:

git clone https://github.com/FlorianBruniaux/node-dep-scope.git
cd node-dep-scope
npm install && npm run build && npm install -g .

Quick Start

cd /path/to/your/project

dep-scope init                        # configure dep-scope for your project (interactive)
dep-scope scan                        # full scan
dep-scope scan --root                 # scan full project, including scripts/ tools/ bin/
dep-scope scan --check-duplicates     # include duplicate detection
dep-scope scan --check-transitive     # surface transitive polyfills (e18e database)
dep-scope scan --each-workspace       # monorepo: scan each package individually
dep-scope migrate                     # generate migration prompts for all candidates
dep-scope migrate lodash              # target a specific package
dep-scope report -o ./audit.md
