# GenGen

[![NPM version](https://img.shields.io/npm/v/@luxbss/gengen.svg)](https://www.npmjs.com/package/@luxbss/gengen) [![license](https://img.shields.io/github/license/luxoft/gengen)](https://github.com/Luxoft/gengen/blob/master/LICENSE.txt) [![GitHub contributors](https://img.shields.io/github/contributors/luxoft/gengen)](https://github.com/Luxoft/gengen/graphs/contributors/)

This tool generates models and [Angular](https://angular.io/) services based on generated [Swagger JSON](https://swagger.io/specification/).

# Getting Started

First of all you make sure that swagger.json is accessable.

> Location by default is https://localhost:5001/swagger/v1/swagger.json. You can override it. See [all options](https://github.com/Luxoft/gengen#all-options)

### Generate all API

```shell
gengen g --all
```

### Generate a part of API

1. Initialize empty rule set

```shell
    gengen init
    ```

2. Generate list of available endpoints

```shell
    gengen g:c
    ```

3. Describe endpoints who will be generated

```ts
    import { Endpoints } from './endpoints';

export default new Set([Endpoints.ProductService.GetProducts, Endpoints.CategoryService.AddCategory]);
    ```

4. Generate specified routes
    ```shell
    gengen g
    ```

### Options

### Option details

#### aliasName

Alias provides:

1. Prefixes for model and service files
2. A way to specify dynamic basePath for services.

Example:

```shell
gengen --aliasName myalias
```

GenGen would create files myalias-models.ts, myalias-services.ts in _output_ directory. And we could override services basePath with following code

```ts
window.__gengen__basePathMap = {
    myalias: 'https://myexternalapi/api'
};
```

#### withRequestOptions

GenGen would generate optional parameter `options` for each method in services. With which you could provide any additional request options from the interface below (IAngularHttpRequestOptions).

Example:

```ts
interface IAngularHttpRequestOptions {
    headers?: HttpHeaders | { [header: string]: string | string[] };
    observe?: 'body' | 'response';
    params?: HttpParams | { [param: string]: string | string[] };
    reportProgress?: boolean;
    responseType?: 'json' | 'blob';
    withCredentials?: boolean;
}

@Injectable({
    providedIn: 'root'
})
export class ExampleService extends BaseHttpService {
    // ...

public methodName(options?: IAngularHttpRequestOptions): Observable<void> {
        return this.post<string>(`methodName`, options);
    }

// ...
}

@Component(
    // ...
)
export class MyComponent {
    constructor(private exampleService: ExampleService) {
        this.exampleService.methodName({
            withCredentials: true
        });
    }
}
```

#### unstrictId

By default, GenGen converts all 'id' properties from string type to custom Guid type. You can disable this behaviour by using it option

Example:

```ts
public static toDTO(model: Partial<Product>): IProduct {
    return {
        // ...
        id: model.id ? model.id.toString() : Guid.empty.toString(),
        // ...
    };
}

public static fromDTO(dto: IProduct): Product {
    // ...
    model.id = new Guid(dto.id);
    // ...
}
```
