name: bundle-checker description: Analyze bundle size and get AI suggestions to reduce it. Use when your builds are getting bloated.

Bundle Checker

Your bundle is 2MB and you don't know why. This tool analyzes your build output and tells you exactly what's eating up space and how to fix it.

One command. Zero config. Just works.

Quick Start

npx ai-bundle-check

What It Does

Analyzes your bundle composition
Identifies the largest dependencies
Suggests tree-shaking opportunities
Recommends lighter alternatives

Usage Examples

# Analyze current project
npx ai-bundle-check
 
# Analyze specific directory
npx ai-bundle-check ./my-project/
 
# Get detailed breakdown
npx ai-bundle-check --verbose

Best Practices

Check before shipping - catch size regressions early
Consider alternatives - moment.js vs date-fns makes a huge difference
Dynamic imports - split code that isn't needed immediately
Monitor trends - track bundle size in CI

When to Use This

Your app loads slowly and you suspect the bundle
Adding a new dependency and want to check the impact
Performance audit flagged JavaScript size
CI bundle size check is failing
