SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps developers reduce JavaScript bundle sizes and improve perceived performance in Next.js apps by providing a structured approach to analysis and optimization across tooling (Webpack and Turbopack), dynamic imports, and code-splitting.

Core Features & Use Cases

Bundle analysis with @next/bundle-analyzer to identify large dependencies, duplicates, and opportunities for splitting.
Dynamic imports and route-based code-splitting to reduce initial payloads and improve caching.
Webpack/Turbopack configuration guidance, dependency analysis, and performance budgets to enforce size targets.

Quick Start

Run a bundle analysis on your Next.js project and apply the recommended splitting and optimization changes.

FAQPage Schema

How do I reduce JavaScript bundle size in a Next.js app?▼

To reduce JavaScript bundle size in Next.js, you can apply code-splitting, tree-shaking, and dynamic imports. This skill provides structured analysis and configuration guidance to identify large dependencies and enforce performance budgets for smaller payloads.

How do I use @next/bundle-analyzer to find large dependencies in Next.js?▼

You can use @next/bundle-analyzer to find large dependencies by running a bundle analysis on your Next.js project. This skill provides setup guidance to configure the analyzer, identify duplicates, and discover opportunities for code-splitting.

Does this Next.js bundle optimization guidance work with Turbopack?▼

Yes, this bundle optimization guidance works with Turbopack as well as Webpack. It covers configuration and optimization strategies for both bundlers to help you reduce initial load sizes and improve caching in your Next.js application.

What's the best way to implement route-based code-splitting in Next.js?▼

The best way to implement route-based code-splitting in Next.js is by using dynamic imports to lazy load components. This skill provides practical examples and checklists to configure splitChunks and define measurable targets for your initial load.

How do I set performance budgets for my Next.js Webpack build?▼

You can set performance budgets for your Next.js Webpack build by defining measurable size targets for initial load and total payload. This skill provides checklists to enforce these limits during development and production builds.

Why are my Next.js dynamic imports not reducing the initial bundle size?▼

If dynamic imports are not reducing initial bundle size, you may need to adjust splitChunks configuration or ensure tree-shaking is properly applied. This skill helps analyze your bundle to verify lazy loading and identify remaining large dependencies.
