@traceletdev/next

Tracelet plugin for Next.js projects.

Installation

npm install -D @traceletdev/cli @traceletdev/next

Usage

After installing, add a postbuild script to your package.json:

{
  "scripts": {
    "postbuild": "tracelet-next collect"
  }
}

Or run manually after building:

npm run build
npx tracelet-next collect

This will generate .tracelet/stats.json which is used by tracelet lint to check performance budgets.

How it works

The plugin reads Next.js build manifests (.next/build-manifest.json, .next/app-build-manifest.json, etc.) to:

• Detect all routes (including dynamic routes)
• Calculate gzip-compressed JavaScript sizes per route
• Identify third-party JavaScript bundles
• Generate statistics for tracelet linting

Configuration

Ensure you have a tracelet.config.json file in your project root. See the main tracelet documentation for configuration options.
