Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

## 🎯 Why MardinJS?

Tired of bloated bundles slowing down your app? MardinJS is the CLI tool that tells you exactly what's weighing down your webpack bundles and how to fix it.

```bash
# Before MardinJS 🤔
"Why is my bundle so big?"

# After MardinJS 🎉
"Ah! React DOM is 1.2MB - time to implement code splitting!"

✨ What's in the Box?

📊 Smart Bundle Analysis

  • Size Breakdown: See exactly where every kilobyte is going
  • Gzip Estimates: Know your real-world transfer sizes
  • Asset Ranking: Instantly spot your largest dependencies
  • Entry Point Tracking: Understand your bundle structure

🔧 Actionable Insights

  • Tree-shaking Tips: Find unused code that's tagging along
  • Code Splitting Suggestions: Know when and where to split
  • Performance Alerts: Get warned about bundle bloat
  • Optimization Recipes: Specific fixes for your exact situation

⚡ Production Ready

  • Config Generator: One command = production-optimized webpack config
  • Build Comparisons: See development vs production differences
  • Best Practices: Industry-standard optimizations out of the box

🚀 Lightning Quick Start

Installation

# Global install (recommended)
npm install -g mardinjs

# Or use directly with npx
npx mardinjs analyze

Your First Analysis

cd your-webpack-project
mardin analyze

Go Pro Mode

# See production-optimized bundle
mardin analyze --production

# Generate optimized config
mardin optimize

# Custom webpack config
mardin analyze --config webpack.prod.js

📈 Real Results You'll See

Before Optimization

📊 MardinJS Bundle Report
==================================================

📦 Bundle Summary:
   Total size: 2.4 MB 😱
   JavaScript: 2.3 MB (8 files)
   CSS: 100 kB (2 files)

📈 Largest Offenders:
   react-dom.js: 1.2 MB (gzip: ~360 kB)
   lodash.js: 600 kB (gzip: ~180 kB) 
   moment.js: 300 kB (gzip: ~90 kB)

💡 Optimization Suggestions:
   1. 🚨 Bundle exceeds 2MB - users on 3G will suffer!
   2. 📦 Use lodash-es for tree-shaking (save ~400kB)
   3. 🗑️ Replace moment.js with date-fns (save ~250kB)
   4. 🔀 Implement route-based code splitting

After Optimization

📊 MardinJS Bundle Report  
==================================================

📦 Bundle Summary:
   Total size: 450 kB ✅
   JavaScript: 350 kB (12 files) 
   CSS: 100 kB (2 files)

🎯 Optimization Results:
   ✅ 81% size reduction!
   ✅ Code splitting implemented
   ✅ Tree-shaking working
   ✅ 2.1s faster load time on 3G

🛠 Advanced Usage

Production Analysis

# See your minified, optimized bundle
mardin analyze --production

# Output:
# 📦 Bundle Summary:
#    Total size: 147 kB (was 1.2MB - 88% smaller!)
#    ✅ Production optimizations working

Custom Config Analysis

# Test different webpack configurations
mardin analyze --config webpack.staging.js
mardin analyze --config configs/prod.webpack.js

Optimization Config

# Generate production-ready webpack config
mardin optimize

# Creates webpack.mardin.config.js with:
# - Advanced code splitting
# - Optimal chunk strategy  
# - Tree-shaking enabled
# - Minification settings
# - Performance budgets

🏗 How It Works

MardinJS uses a multi-step analysis process:

  1. 🔍 Bundle Scanning - Runs webpack and extracts detailed stats
  2. 📐 Size Analysis - Measures every asset with gzip estimates
  3. 🎯 Pattern Recognition - Identifies common optimization opportunities
  4. 💡 Smart Suggestions - Provides specific, actionable recommendations
  5. ⚙️ Config Generation - Creates optimized webpack configurations

💡 Pro Tips

Integrate with Your Workflow

# Add to package.json scripts
{
  "scripts": {
    "analyze": "mardin analyze --production",
    "analyze:dev": "mardin analyze",
    "optimize:config": "mardin optimize"
  }
}

CI/CD Integration

# Fail build if bundle exceeds limit
mardin analyze --production | grep "Total size" 
# Add your size check logic here

Monitor Bundle Growth

# Track bundle size over time
mardin analyze --production > bundle-stats-$(date +%Y%m%d).txt

🐛 Troubleshooting

"Webpack config not found"

# Specify custom config path
mardin analyze --config custom/path/webpack.config.js

"Command not found"

# Install globally or use npx
npm install -g mardinjs
# or
npx mardinjs analyze

Build errors during analysis

  • MardinJS will show you webpack's exact error messages
  • Fix configuration issues first, then re-run analysis
