Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@luxbss/gengen) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

GenGen

This tool generates models and Angular services based on generated Swagger JSON.

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

Generate all API

gengen g --all

Generate a part of API

Initialize empty rule set
```
gengen init
```
Generate list of available endpoints
```
gengen g:c
```

Describe endpoints who will be generated

import { Endpoints } from './endpoints';

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

Generate specified routes
```
gengen g
```

Option details

aliasName

Alias provides:

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

Example:

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

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:

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:

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);
    // ...
}
