 - **Readability First**: Write code that is easy to read and understand.
 - **Consistency**: Follow the same patterns and conventions throughout the codebase.
 - **Clean Code**: Avoid unnecessary complexity and keep functions small and focused.
+- **SOLID Principles**: Follow SOLID design principles to create more maintainable, flexible, and scalable code.
+
+## SOLID Design Principles
+
+SOLID is an acronym for five design principles that help make software designs more understandable, flexible, and maintainable:
+
+- **Single Responsibility Principle (SRP)**: A class should have only one reason to change, meaning it should have only one job or responsibility.
+
+  ```typescript
+  // Good - Each class has a single responsibility
+  class UserAuthentication {
+    authenticate(username: string, password: string): boolean {
+      // Authentication logic
+    }
+  }
+
+  class UserRepository {
+    findById(id: string): User {
+      // Database access logic
+    }
+  }
+
+  // Bad - Class has multiple responsibilities
+  class UserManager {
+    authenticate(username: string, password: string): boolean {
+      // Authentication logic
+    }
+
+    findById(id: string): User {
+      // Database access logic
+    }
+
+    sendEmail(user: User, message: string): void {
+      // Email sending logic
+    }
+  }
+  ```
+
+- **Open/Closed Principle (OCP)**: Software entities should be open for extension but closed for modification.
+
+  ```typescript
+  // Good - Open for extension
+  interface PaymentProcessor {
+    processPayment(amount: number): void;
+  }
+
+  class CreditCardProcessor implements PaymentProcessor {
+    processPayment(amount: number): void {
+      // Credit card processing logic
+    }
+  }
+
+  class PayPalProcessor implements PaymentProcessor {
+    processPayment(amount: number): void {
+      // PayPal processing logic
+    }
+  }
+
+  // New payment methods can be added without modifying existing code
+  ```
+
+- **Liskov Substitution Principle (LSP)**: Objects of a superclass should be replaceable with objects of subclasses without affecting the correctness of the program.
+
+  ```typescript
+  // Good - Derived classes can substitute base class
+  class Rectangle {
+    constructor(
+      protected width: number,
+      protected height: number,
+    ) {}
+
+    setWidth(width: number): void {
+      this.width = width;
+    }
+
+    setHeight(height: number): void {
+      this.height = height;
+    }
+
+    getArea(): number {
+      return this.width * this.height;
+    }
+  }
+
+  class Square extends Rectangle {
+    constructor(size: number) {
+      super(size, size);
+    }
+
+    // Preserve behavior when overriding methods
+    setWidth(width: number): void {
+      super.setWidth(width);
+      super.setHeight(width);
+    }
+
+    setHeight(height: number): void {
+      super.setWidth(height);
+      super.setHeight(height);
+    }
+  }
+  ```
+
+- **Interface Segregation Principle (ISP)**: Clients should not be forced to depend on interfaces they do not use.
+
+  ```typescript
+  // Good - Segregated interfaces
+  interface Printable {
+    print(): void;
+  }
+
+  interface Scannable {
+    scan(): void;
+  }
+
+  class AllInOnePrinter implements Printable, Scannable {
+    print(): void {
+      // Printing logic
+    }
+
+    scan(): void {
+      // Scanning logic
+    }
+  }
+
+  class BasicPrinter implements Printable {
+    print(): void {
+      // Printing logic
+    }
+  }
+
+  // Bad - Fat interface
+  interface OfficeMachine {
+    print(): void;
+    scan(): void;
+    fax(): void;
+    staple(): void;
+  }
+
+  // Classes must implement methods they don't need
+  ```
+
+- **Dependency Inversion Principle (DIP)**: High-level modules should not depend on low-level modules. Both should depend on abstractions.
+
+  ```typescript
+  // Good - Depending on abstractions
+  interface Logger {
+    log(message: string): void;
+  }
+
+  class ConsoleLogger implements Logger {
+    log(message: string): void {
+      console.log(message);
+    }
+  }
+
+  class FileLogger implements Logger {
+    log(message: string): void {
+      // File logging logic
+    }
+  }
+
+  class UserService {
+    constructor(private logger: Logger) {}
+
+    createUser(user: User): void {
+      // Create user logic
+      this.logger.log(`User created: ${user.name}`);
+    }
+  }
+
+  // The UserService depends on the abstraction (Logger interface)
+  // not on concrete implementations
+  ```
+
+Following these principles improves code quality by:
+
+- Reducing coupling between components
+- Making the system more modular and easier to maintain
+- Facilitating testing and extension
+- Promoting code reuse

+

+      <li>{{ item.name }}</li>
+      } @empty {
+      <li>No items available</li>
+      }
+    </ul>
+
+    @switch (userRole) { @case ('admin') {
+    <app-admin-dashboard />
+    } @case ('manager') {
+    <app-manager-dashboard />
+    } @default {
+    <app-user-dashboard />
+    } }
+  </div>

+    <app-user-dashboard
+      *ngIf="userRole !== 'admin' && userRole !== 'manager'"
+    ></app-user-dashboard>
+  </div>
+  ```
+
+  - When using `@for`, always specify the `track` expression to optimize rendering performance:
+    - Use a unique identifier property (like `id` or `uuid`) when available
+    - Only use `$index` for static collections that never change
+    - Avoid using non-unique properties that could result in DOM mismatches
+  - Leverage contextual variables in `@for` blocks:
+    - `$index` - Current item index
+    - `$first` - Boolean indicating if this is the first item
+    - `$last` - Boolean indicating if this is the last item
+    - `$even` - Boolean indicating if this index is even
+    - `$odd` - Boolean indicating if this index is odd
+    - `$count` - Total number of items in the collection
+
+  ```html
+  <!-- Good - Using contextual variables -->
+  @for (item of items; track item.id; let i = $index, isLast = $last) {
+  <li [class.last-item]="isLast">{{ i + 1 }}. {{ item.name }}</li>
+  }
+  ```
+
+  - Use the `@empty` block with `@for` to handle empty collections gracefully
+  - Store conditional expression results in variables for clearer templates:
+
+  ```html
+  <!-- Good - Storing expression result in variable -->
+  @if (user.permissions.canEditSettings; as canEdit) {
+  <button [disabled]="!canEdit">Edit Settings</button>
+  }

+# Core Logging
+
+## Overview
+
+The Core Logging library provides a centralized logging service for the ISA Frontend application. It offers a structured way to log messages, errors, and other information across the application, with support for different log levels and output destinations.
+
+## Features
+
+- Multiple log levels (trace, debug, info, warn, error)
+- Configurable logging targets (console, remote server, etc.)
+- Context-aware logging with metadata support
+- Production/development mode detection
+- Filtering capabilities based on log level or context
+
+## Core Concepts
+
+### Log Sinks
+
+Log sinks are destinations where log messages are sent. The library supports multiple sinks operating simultaneously, allowing you to:
+

+### LoggingService
+
+The main service for logging functionality.
+
+#### Methods
+
+| Method                                                     | Description                 |
+| ---------------------------------------------------------- | --------------------------- |
+| `trace(message: string, context?: unknown)`                | Logs trace information      |
+| `debug(message: string, context?: unknown)`                | Logs debug information      |
+| `info(message: string, context?: unknown)`                 | Logs informational messages |
+| `warn(message: string, context?: unknown)`                 | Logs warning messages       |
+| `error(message: string, error?: Error, context?: unknown)` | Logs error messages         |
+
+### Create Custom Sink
+
+#### Custom Sink Class
+
+```typescript
+class MyCustomSink implements Sink {
+  #loggerAPI = inject(LoggerApi);
+  log(
+    level: LogLevel,
+    message: string,
+    context?: unknown,
+    error?: Error,
+  ): void {
+    // ... Do Stuff
+  }
+}
+```
+
+### Custom Sink Function
+
+```typescript
+const myCustomSinkFn: SinkFn = () => {
+  const loggerAPI = inject(LoggerApi);
+  return (
+    level: LogLevel,
+    message: string,
+    context?: unknown,
+    error?: Error,
+  ) => {
+    // ... Do Stuff
+  };
+};
+```
+
+### LogLevel Enum
+
+```typescript
+export const enum LogLevel {
+  Trace = 'trace',
+  Debug = 'debug',
+  Info = 'info',
+  Warn = 'warn',
+  Error = 'error',
+  Off = 'off',
+}
+```
+
+## Configuration
+
+### Global Configuration
+
+Configure the logging service globally during application initialization:
+
+```typescript
+// In your app.config.ts or similar initialization file
+
+import { provideLogging, withSink, ConsoleLogSink } from '@isa/core/logging';
+
+const isProduction = environment.production;
+export const appConfig: ApplicationConfig = {
+  providers: [
+    // ...other providers
+    provideLogging(
+      withLogLevel(isProduction ? LogLevel.Warn : LogLevel.Debug),
+      withSink(ConsoleLogSink),
+      withSink(MyCustomSink),
+      withSinkFn(myCustomSinkFn),
+    ),
+  ],
+};
+```
+
+### Context Configuration
+
+Configure the logging service for a specific context
+
+```typescript
+@Component({
+  providers: [provideLoggerContext({ component: 'MyComponent', ... })]
+})
+export  class MyComponent {}
+#logger = logger();
+```
+
+## Usage
+
+```typescript
+import { logger, LogLevel } from  '@isa/core/logging';
+
+@Component({
+// ...
+})
+export  class MyComponent implements OnInit {
+
+  #logger = logger();
+
+  ngOnInit() {
+	this.logger.info('Component initialized', { componentName: 'MyComponent' });
+  }
+
+  processData(data: any) {
+    try {
+      // Process data
+      this.logger.debug('Data processed successfully', { dataId: data.id });
+    } catch (error) {
+      this.logger.error('Failed to process data', error as Error, {
+      dataId: data.id,
+    });
+  }
+}
+```
