# SCA Runner

Wrapper for npm audit and Trivy to perform Software Composition Analysis.

## Prerequisites

At least one of these tools must be installed:

```bash
# npm audit (built into npm)
npm --version

# Trivy (recommended for multi-language support)
brew install trivy
# or
curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/main/contrib/install.sh | sh -s -- -b /usr/local/bin
```

## Usage

```bash
# Scan with auto-detection (prefers Trivy if available)
npx sca-runner .

# Force specific scanner
npx sca-runner . --scanner npm
npx sca-runner . --scanner trivy

# JSON output
npx sca-runner . --json

# Check available scanners
npx sca-runner --check

# Scan specific package file
npx sca-runner ./package-lock.json --scanner npm
```

## Supported Package Managers

| Scanner | Languages/Files |
|---------|-----------------|
| npm audit | Node.js (package-lock.json) |
| Trivy | Node.js, Python, Go, Ruby, Rust, Java, .NET |
