🌟 Features

• Dynamic URLs: Uses route parameters to display budget details dynamically.
• Business Logic in Services: Implements service-based architecture for cleaner and maintainable code.
• Reactive Forms: Uses Angular's FormGroup and FormControl for dynamic, real-time form validation and management.
• Filtering & Sorting: Allows users to filter budget entries and sort results based on different criteria.
• State Management: Ensures reactive and efficient handling of budget data.

🛠️ Key Features & Implementation

🌍 Dynamic URLs

The application utilizes Angular's ActivatedRoute to dynamically display budget details based on the URL.

Example:

this.route.paramMap.subscribe(params => {
  const id = params.get('id');
  this.loadBudgetDetails(id);
});

Routes Configuration:

const routes: Routes = [
  { path: 'budget/:id', component: BudgetDetailComponent }
];

🔹 Business Logic in Services

The application follows best practices by handling budget calculations and data processing inside Angular services, keeping components lean and focused on presentation.

Example of a budget service:

@Injectable({ providedIn: 'root' })
export class BudgetService {
  private budgets: Budget[] = [];

  getBudgets(): Budget[] {
    return [...this.budgets];
  }

  addBudget(budget: Budget): void {
    this.budgets.push(budget);
  }
}

🔹 Reactive Forms

Instead of template-driven forms, this project leverages Reactive Forms for better control and dynamic validation.

Example:

this.budgetForm = this.fb.group({
  name: ['', Validators.required],
  amount: [0, [Validators.required, Validators.min(1)]]
});

🔹 Filtering & Sorting

Users can filter budget items based on predefined criteria and sort results dynamically.

Example:

filterBudgets(criteria: string): Budget[] {
  return this.budgets.filter(budget => budget.category.includes(criteria));
}

sortBudgets(order: 'asc' | 'desc'): Budget[] {
  return this.budgets.sort((a, b) => order === 'asc' ? a.amount - b.amount : b.amount - a.amount);
}
