# Request Handlers with `@yaagoub/decorators`

This guide demonstrates how to handle HTTP requests in Angular using decorators from the `@yaagoub/decorators` library.
## Setup

Use `provideDecoratorsConfig` in your `app.config.ts` to initialize global configuration:

```ts
import { provideDecoratorsConfig } from '@yaagoub/decorators';

export const appConfig: ApplicationConfig = {
  providers: [
    provideDecoratorsConfig(),
  ],
};
```
## Example
```ts
import { HttpClient, Get, returnType } from '@yaagoub/decorators';
import { Observable } from 'rxjs';

@HttpClient('/sources/api/v1')
export class ViewsService {
  @Get({
    path: '/views',
    options: {
      responseType: 'json',
      headers: {
        'Content-Type': 'application/json',
        'Authorization': 'Bearer token',
      },
    },
  })
  getViews(): Observable<any> {
    return returnType<any>();
  }
}

// Usage
const views = new ViewsService();

views.getViews().subscribe({
  next: (res) => console.log(res),
  error: (err) => console.error(err),
  complete: () => console.log('Completed'),
});
```
## Usage

```typescript
import { BasePath, Get, Res, HttpRespose } from '@yaagoub/decorators';

@HttpClient('/sources/api/v1')
@DefaultHeaders({
  'x-test': 'class-header',
  'x-test-writable': 'class-header-write', // this header is writable (4º priority)
  'x-class-only': 'class-only-value',
})
export class ViewsService {
 @Get({
    path: '/testMethod',
    options: {
      headers: {
        'x-test-1': 'decorator-header-1',
        'x-test-writable': 'decorator-header-write', // this header is writable (2º priority)
        'x-get-options-only': 'get-options-only-value',
      },
    },
  })
  @Headers({
    'x-test-2': 'method-header-2',
    'x-test-writable': 'method-header-write', // this header is writable (3º priority)
    'x-method-only': 'method-only-value',
  })
  getViews(
    @Header('x-test-3') header: string,
    @Header('x-test-writable') writableHeader: string, // this header is writable (1º priority)
  ): Observable<any> {
    return returnType();
  }
}

const views = new ViewsService()
views.getViews('x-test-3-value','x-test-writable-value').subscribe({
  next: (res: any) => {
    console.log(res)
  },
  error: (err: any) => {
    console.error(err)
  },
  complete: () => {
    console.log('completed')
  }
})
;


```

### Mapper Decorator

```typescript
import { Mapper } from '@yaagoub/decorators';

interface DestinationType {
  property1: string;
  property2: number;
  propertyC: string;
}
interface SourceType {
  property1: string;
  property2: number;
  propertyC: string;
}

export class MapperToDestination {
  @Mapper<DestinationType>()
  static toDestination(source: SourceType): DestinationType {
    return source as any;
  }
}

const example = new ExampleClass();
const result = example.exampleMethod();
console.log(result);
// Output: { propertyA: "example", propertyB: 42, propertyC: "example" }
```
