What You'll Learn

When you initialize a project, Claude Code creates a sophisticated setup. This module walks through each piece and ensures it's configured correctly.

What Claude Code Creates

Next.js - The framework that makes everything work TypeScript - A safety layer for code that catches errors Tailwind CSS - Styling without writing CSS

Deliverable: Create New Project

Purpose: Scaffold a complete Next.js 14 project.

Expert Role: Full-Stack Developer specializing in Next.js

Tools to Use: Bash (npm/npx commands), File system (write)

Expected Output

  • Complete Next.js 14 project scaffolded
  • TypeScript configured in strict mode
  • Tailwind CSS installed and configured

Prompt Template

Act as a full-stack developer specializing in Next.js. Create a new
Next.js 14 project with:
- TypeScript in strict mode
- Tailwind CSS with a custom configuration
- App Router (not Pages Router)
- Path aliases so I can import from @/components

Name the project: [your-project-name]

After creating it, explain what you made and how to run it.

Deliverable: Configure TypeScript

Purpose: Set up TypeScript with strict mode and path aliases.

Expert Role: TypeScript Configuration Expert

Tools to Use: File system (edit tsconfig.json)

Expected Output

  • Updated tsconfig.json with strict mode
  • Path aliases configured for clean imports

Prompt Template

Act as a TypeScript configuration expert. Configure TypeScript with
strict mode to catch errors early. Add path aliases so imports look like:
  import { Button } from '@/components';
instead of:
  import { Button } from '../../../components';

Show me the changes you made to tsconfig.json.
