## What it is
The official code repository for the book 'Node.js Design Patterns, Third Edition' by Mario Casciaro and Luciano Mammino, published by Packt. It contains working examples and practice exercises covering Node.js patterns such as async flows, the event loop, scalability, testing, and microservices.

## Use cases
- learn node.js design patterns
- understand how the event loop works
- master callbacks promises and async flows in node
- find examples for building scalable node.js applications
- practice exercises for node.js architecture
- learn microservices and messaging patterns in node.js

## When to choose
- you are reading the book and want the accompanying source code
- you want hands-on examples of node.js design patterns
- you want to share or browse exercise solutions from the community

## When to avoid
- you need a production-ready library or framework to install
- you want a general node.js tutorial not focused on design patterns
- you need up-to-date examples for the latest node.js runtime features
