Angular Architecture is divided into different parts like Component, Template, Directive, Service, and Module. Before you start to develop your application, you should have knowledge about the purpose of each part of the application. So that you can make your application smoother and faster. Below is the figure of angular architecture. Angular Architecture In this chapter, we will see each term in detail.

Solid Principle

SOLID Principle What are the SOLID principles? Five object-oriented design principles  help make code: Maintainable (easy to change without breaking things) Extensible (easy to add new features) Testable (easy to write unit tests) Understandable (easy for other developers to read) The five principles: S – Single Responsibility Principle (SRP) One class = one reason to change. O – Open/Closed Principle (OCP) Open for extension, closed for modification. L – Liskov Substitution Principle (LSP) Subclasses should work wherever base classes work (no broken contracts). I – Interface Segregation Principle (ISP) Clients should not be forced to depend on methods they don’t use. D – Dependency Inversion Principle (DIP) Depend on abstractions, not concrete classes. Why are we using SOLID principles? Reduce bugs when requirements change → You can modify code without breaking unrelated parts. Improve maintainability → Code is easier to und...
