In computer programming, SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible, and maintainable. The principles are a subset of many principles promoted by American software engineer and instructor Robert C. Martin, first introduced in his 2000 paper Design Principles and Design Patterns.

At the time of publication of this code there is no real world example of these principles. Articles online and code bases to demonstrate "how to implement" are done so poorly. This repository is attempting to fill that gap and wish to provide engineers better path of learning to integrate these powerful principles as part of their workflow.

Followings are implementation of 5ive Principles in Node.js using TypeScript, each folder contains a README.md explaining each scenario in agile format for user story. Finally, there is an example.ts file in each folder that is specs/unit test to demonstrate execution point of system.

• Single-responsibility Principle
• Open–closed Principle
• Liskov Substitution Principle
• Interface Segregation Principle
