Single Responsibility Principle (S):

  • Each component has one specific responsibility
  • TaskFormComponent handles task creation
  • TaskItemComponent manages individual task display and editing
  • TaskListComponent handles task list rendering
  • Separate services for task management and validation

Open/Closed Principle (O):

  • Components are open for extension but closed for modification
  • New validation rules can be added without changing existing code
  • New task features can be added by extending interfaces

Liskov Substitution Principle (L):

  • Services implement interfaces (ITaskService, IValidationService)
  • Different implementations can be substituted without breaking the application
  • Components depend on abstractions, not concrete implementations

Interface Segregation Principle (I):

  • Separate interfaces for different responsibilities
  • ITaskService for task operations
  • IValidationService for validation logic
  • Components only depend on interfaces they need

Dependency Inversion Principle (D):

  • High-level components depend on abstractions
  • Dependencies are injected rather than created inside components
  • Use of interfaces enables easy testing and substitution

Modularity:

  • Components are broken down into smaller, focused pieces
  • Clear separation between UI components and business logic

Maintainability:

  • Each piece is independently testable
  • Changes to one component don't affect others
  • Easy to add new features or modify existing ones

Reusability:

  • Components and services can be reused in other parts of the application
  • Validation service can be used for other forms
  • Task service pattern can be applied to other data types
