Portable Abstractions and Patterns for Node.js

This framework is part of the Pip.Services project. It provides portable abstractions and patterns that can be used to implement non-trivial business logic in applications and services.

This framework's key difference is its portable implementation across a variety of different languages. It currently supports Java, .NET, Python, Node.js, and Golang. The code provides a reasonably thin abstraction layer over most fundamental functions and delivers symmetric implementation that can be quickly ported between different platforms.

The framework's functionality is decomposed into several packages:

• Commands - commanding and eventing patterns
• Config - configuration framework
• Convert - soft value converters
• Data - data patterns
• Errors - application errors
• Random - random data generators
• Refer - locator (IoC) pattern
• Reflect - reflection framework
• Run - execution framework
• Validate - validation framework
