Claude Code Examples & Templates: Ready-to-Use Patterns

Copy these Claude Code examples to start building immediately. Each template is production-ready and demonstrates core Claude Code capabilities you can use in your projects today.

Quick Start Web App

Build a complete React application in minutes with this template:

claude "Create a React todo app with TypeScript, Tailwind CSS, and local storage persistence. Include add, edit, delete, and filter functionality."

This generates:

• TypeScript React components
• Tailwind CSS styling
• Local storage integration
• Full CRUD operations
• Responsive design

Perfect for prototyping or learning React patterns. Expand it into a full project by adding authentication or API integration using our Configuration Basics guide.

API Backend Template

Create a Node.js Express API with authentication:

claude "Build an Express.js API with JWT authentication, user registration, login, password hashing with bcrypt, and protected routes. Include error handling middleware."

You'll get:

• JWT token authentication
• Password hashing with bcrypt
• Input validation middleware
• Error handling patterns
• Protected route examples

This template handles the security basics so you focus on business logic. Scale it further with database integration covered in our First Project tutorial.

Database Schema Generator

Generate PostgreSQL schemas with relationships:

claude "Create a PostgreSQL schema for an e-commerce app with users, products, orders, and order_items tables. Include proper foreign keys, indexes, and sample data insertion queries."

Creates:

• Normalized table structures
• Foreign key relationships
• Performance indexes
• Sample INSERT statements
• Proper data types

Use this pattern for any domain - just replace "e-commerce" with your use case. When you're ready to implement, check our Installation Guide for database setup.

Testing Framework Setup

Generate complete test suites with this template:

claude "Set up Jest testing for a React TypeScript project. Include unit tests for components, integration tests for API calls, and mock data generators. Add test scripts to package.json."

This provides:

• Jest configuration
• Component testing utilities
• API mocking patterns
• Test data generators
• NPM script automation

Essential for production applications. Learn more about project structure in our Configuration Basics.

Mobile-First Responsive Template

Create mobile-optimized layouts instantly:

claude "Build a responsive landing page with mobile-first design, hero section, feature cards, testimonials, and contact form. Use CSS Grid and Flexbox with proper breakpoints."

Generates:

• Mobile-first CSS patterns
• Responsive grid layouts
• Modern flexbox usage
• Cross-browser compatibility
• Accessibility basics

Common Development Patterns

Error Handling Template

claude "Create a comprehensive error handling system for a Node.js app with custom error classes, async error catching, logging, and user-friendly error responses."

State Management Setup

claude "Set up Redux Toolkit with TypeScript for a React app. Include store configuration, slices for user and app state, async thunks, and React component integration examples."

Form Validation Pattern

claude "Create form validation with React Hook Form and Zod schema validation. Include real-time validation, error messages, and submit handling with TypeScript types."

Usage Tips

Start Specific: The more details you provide, the better Claude Code understands your needs. Include technology preferences, styling requirements, and functionality details.

Iterate Quickly: Use these templates as starting points, then ask Claude Code to modify specific parts. "Add user authentication" or "Convert to TypeScript" work great as follow-up requests.

Combine Templates: Mix patterns from different examples. Start with the web app template, then add API backend functionality and database integration.
