SOLID Principles For NestJS: Clean Code Made Easy

SOLID principles in NestJS ensure maintainable & scalable code. SRP separates concerns, OCP allows extension, LSP enables service swapping, ISP splits interfaces, and DIP decouples classes from dependencies for simplicity & extensibility.

When building robust and maintainable applications with NestJS, the SOLID principles offer a proven path to writing clean and scalable code. Each principle—Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion—guides how to design your application for simplicity and extensibility.
Let’s dive into these principles with examples and flowcharts! 🌟


  
  
  🪩 1. Single Responsibility Principle (SRP)

A class should have one and only one reason to change.  

In NestJS, separation of concerns is achieved by dividing responsibilities across contro...
