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

How It Works

Scans your package.json and build output, identifies heavy dependencies, and sends the analysis to GPT-4o-mini. The AI knows common bundle bloat patterns and suggests specific optimizations like switching libraries or adding tree-shaking config.
