Analyze Bundle Size

---
description: Visualize and reduce your production build size
---

1. **Install Analyzer**:
- Install the Next.js bundle analyzer.
// turbo
- Run npm install @next/bundle-analyzer

2. **Configure next.config.js**:
- Wrap your config.

const withBundleAnalyzer = require('@next/bundle-analyzer')({
     enabled: process.env.ANALYZE === 'true',
   })
   module.exports = withBundleAnalyzer({
     // Other config options
   })

3. **Run Analysis**:
- Build with analysis enabled.
// turbo
- Run ANALYZE=true npm run build

4. **Pro Tips**:
- Works with **TurboPack** in Next.js 15.
- Look for large libraries (like lodash or moment) that can be tree-shaken or replaced.
- Use import { x } from 'package' instead of import package from 'package'.
