A comprehensive collection of design pattern examples implemented using React and TypeScript. This repository demonstrates various design patterns in a practical, interactive way with real-world React applications.
This repository contains working examples of design patterns implemented in React. Each pattern is demonstrated through a complete, runnable application that showcases the pattern's benefits, use cases, and implementation details.
- Learn by doing: Interactive examples that you can run and modify
- Real-world context: Patterns demonstrated in practical React applications
- Type safety: All examples use TypeScript for better code quality
Location: creational/factory-method/
A logistics management system that demonstrates the Factory Method pattern. Create different types of transportation (Truck, Ship, Plane) using factory methods without directly instantiating concrete classes.
Key Features:
- Dynamic object creation based on type
- Encapsulated creation logic
- Easy to extend with new transportation types
- Type-safe implementation with TypeScript
Example Use Case: When you need to create objects of different types based on runtime conditions, but want to keep the creation logic separate from the business logic.
Tech Stack: React + TypeScript + Vite
- Node.js: v18 or higher
- npm: Package manager
- Modern browser: For running the applications
Each pattern example is a standalone project. Navigate to the specific pattern directory and install dependencies:
# Example: Factory Method Pattern
cd creational/factory-method
npm installEach pattern has its own development server:
# Navigate to the pattern directory
cd creational/factory-method
# Start development server
npm run dev
# Build for production
npm run builddesign-patterns/

- Browse by Pattern: Navigate to the pattern you want to learn about
- Read the Documentation: Each pattern has its own README with detailed explanations
- Run the Example: Start the development server and interact with the application
- Explore the Code: Study the implementation to understand how the pattern works
- Experiment: Modify the code to see how changes affect the pattern's behavior
Patterns that deal with object creation mechanisms, trying to create objects in a manner suitable to the situation.
- ✅ Factory Method: Define an interface for creating objects, but let subclasses decide which class to instantiate
- 🔜 More patterns coming soon...
Patterns that deal with object composition and relationships between objects.
- 🔜 Coming soon...
Patterns that deal with communication between objects and how responsibilities are distributed.
- 🔜 Coming soon...
- React: UI library for building interactive interfaces
- TypeScript: Type-safe JavaScript for better code quality
- Vite: Fast build tool and development server
- Modern ES6+: Latest JavaScript features
Design patterns are reusable solutions to common problems in software design. They are:
- Templates: Provide a template for solving problems
- Language-agnostic: Can be applied in any programming language
- Proven solutions: Tested and refined by the software development community
- Best practices: Represent best practices for object-oriented design
React's component-based architecture makes it an excellent choice for demonstrating design patterns:
- Component composition: Patterns like Factory Method work naturally with React components
- State management: Patterns can be applied to state management and data flow
- Reusability: React's emphasis on reusable components aligns with pattern principles
- Real-world relevance: Most modern web applications use React or similar frameworks
This repository is designed to be a learning resource. Feel free to:
- Add new pattern examples
- Improve existing implementations
- Fix bugs or issues
- Enhance documentation
- Share feedback
This project is open source and available for educational purposes.
Happy Learning! 🎉
