Utilizing a customized TypeScript Rest Client from Swagger in Angular 2

In my current project, I am developing a Meteor web application using Angular 2 and TypeScript. To interact with a REST API, I have utilized Swagger Codegen to generate client code. However, I am facing a challenge as there are no example implementations available on GitHub that demonstrate how to use the REST client effectively.

Within an Angular 2 view component, I have integrated an Angular 2 service (ProductTreeService) and the generated API (both annotated with "@Injectable"):

@Component({
    selector: 'panel-product-selection',
    template,
    providers: [ProductTreeService, UserApi],
    directives: [ProductTreeComponent]
})

export class PanelProductSelectionComponent
{
    private categoriesProductsTree: Collections.LinkedList<CategoryTreeElement>;
    private productTreeService: ProductTreeService;
    private userApi: UserApi;

    constructor(productTreeService: ProductTreeService, userApi: UserApi)
    {
        this.productTreeService = productTreeService;
        this.userApi = userApi;
    }

    ngOnInit(): void
    {
        //...
    }
}

While I have successfully accessed the angular service without any issues, the application encounters errors when attempting to inject UserApi. The main disparity between UserApi and ProductTreeService lies in their constructors: the service has no constructor parameters, whereas the generated API class includes:

constructor(protected http: Http, @Optional()@Inject(BASE_PATH) basePath: string) {
    if (basePath) {
        this.basePath = basePath;
    }
}

Therefore, I am seeking guidance on how to effectively inject the generated API into my application.

To set the URL in my Angular project, I typically utilize the environment.ts file. Within this file, I define a property for the URL like so:

export const environment = {
  production: false,
  baseURL: 'https://example.com/api/v1'
};

Next, I provide this configuration to the service in the app.module file:

providers: [
    { provide: BASE_URL, useValue: environment.baseURL },
  ],

This setup seamlessly integrates with Swagger-generated code.

I hope this information proves helpful! (updated for Angular version 6+)

After conducting further investigations, I was able to find the resolution. The UserApi constructor from the rest client UserApi requires an HTTP provider in the following manner:

constructor(protected http: Http, @Optional()@Inject(BASE_PATH) basePath: string) {
    if (basePath) {
        this.basePath = basePath;
    }
}

Having a background in Java, my initial assumption was that this provider needed to be initialized within the constructor injecting the API. However, as it turns out, this initialization process needs to happen within the NgModule that encompasses the injecting component, as outlined in this discussion.

Implementing this solution resolved the issue for me.

While this question may be dated, the proper method for achieving this is outlined below:

serviceProviders: [
{
  kind: API_BASE_LINK, // alternatively BASE_LINK
  factoryUse: () => { 
      return siteEnvironment.apiBaseLink // or simply return "your designated base link in text form"
  }
}]
