Next.js Architecture & Setup Guide

About

This skill provides a comprehensive blueprint for building scalable Next.js applications using the App Router and Turbopack. It automatically guides developers through selecting optimal tech stacks—such as choosing between Biome and ESLint—while implementing a high-cohesion feature-based directory structure. A key focus is the establishment of a strict design system layer that wraps shadcn/ui components, ensuring long-term maintainability and consistent UI development. By providing a ready-to-use CLAUDE.md template, it aligns AI behavior with project-specific rules, architectural boundaries, and coding standards.

Key Features

• Standardizes testing and validation patterns using Vitest, Testing Library, and Zod.
• Architects scalable feature-based directory structures for high code maintainability.
• Enforces a strict design system layer that abstracts and protects UI primitives.
• Automates tech stack selection between Biome and ESLint/Prettier based on project needs.
• Provides a pre-configured CLAUDE.md template to align AI behavior with project rules.
• 2 GitHub stars

Use Cases

• Refactoring an existing monolithic project into a scalable feature-based architecture.
• Initializing a new production-ready Next.js project with App Router and Turbopack.
• Establishing a professional design system workflow using shadcn/ui and design tokens.
