Description

Analyzes your code to identify which npm packages are actually being used. Helps keep track of your project’s runtime dependencies.

​
Usage

rev-dep node-modules used [flags]

​
Examples

# Analyze from a specific entry point and group by module
rev-dep node-modules used -p src/index.ts --group-by-module

# Count used modules
rev-dep node-modules used --count

# Show files using each module
rev-dep node-modules used --group-by-module-files-count

# Analyze multiple entry points
rev-dep node-modules used -p src/index.ts -p src/server.ts

Use Cases

Track Runtime Dependencies

Identify which npm packages are actually being used in your codebase to maintain an accurate dependency list.

Monorepo Analysis

Use --follow-monorepo-packages to analyze dependencies across workspace packages.

Entry Point Analysis

Group by entry points to see which dependencies are used by different parts of your application.
