ts-complexity-cli

Measure cyclomatic complexity of TypeScript/JavaScript files.

Install

npm install -g ts-complexity-cli

Usage

# Analyze files matching a glob pattern
ts-complexity "src/**/*.ts"

# Only show functions above a complexity threshold
ts-complexity "src/**/*.ts" --threshold 10

# Sort by complexity (descending)
ts-complexity "src/**/*.ts" --sort

# JSON output
ts-complexity "src/**/*.ts" --json

# Summary with averages and distribution
ts-complexity "src/**/*.ts" --summary

# Exclude patterns
ts-complexity "src/**/*.ts" --exclude "**/*.test.ts"

# Combine options
ts-complexity "src/**/*.ts" --threshold 5 --sort --summary

Complexity Levels

| Range | Level | Color | |-------|----------|--------| | 1-5 | Simple | Green | | 6-10 | Moderate | Yellow | | 11+ | Complex | Red |

Exit Codes

• 0 — all functions are below the threshold (or no threshold set)
• 1 — at least one function exceeds the threshold
