How can I read an environment variable from a .NET appSettings.json file in an Angular service?
I'm new to Angular2 and have some questions.
I have a service which requests some JSON data from a Web API:
import Injectable from '@angular/core';
import Http from '@angular/http';
import 'rxjs/add/operator/map';
@Injectable()
export class ReviewService
private actionUrl: string;
constructor(private _http: Http)
this.actionUrl = 'http://api.dc-shop.com/review';
public GetAll = (): any =>
return this._http.get(this.actionUrl)
.map(x => x.json());
I would like to avoid hard coding the API address in the constructor and instead read a setting from appSettings.json which I can use for the action URL at startup for production and localhost servers.
What is the best way of doing this in ASP.NET MVC Core?

Why not to store this in some global service? and call every time from there

Two options I can think of:
1) Put the configuration in environment.ts as well as appSettings.json - access to this is built into angular.
2) Step 1 of your service loads appSettings.json using a straight-forward http.get and then uses the config from it load the required data.
Example of environment.ts
export const environment =
apiUrl: 'http://api.dc-shop.com',
mode: 'prod'
;
Example usage:
import environment from './environment';
constructor(private _http: Http)
this.actionUrl = environment.apiUrl + '/review';
1
I ended up going for option 1 and having a separate environment.ts. The appsettings.json file is not copied to wwwroot and could contain connection strings so it was not the best solution for me.

You can implement this by using Angular Http Intercepter
Add the http://api.dc-shop.com prefix in each request.
Example Code:
Write an Request Intercepter in Your Angular App:
@Injectable()
export class RequestInterceptor implements HttpInterceptor
intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>>
let req_url = req.url
req.clone(url:`http://api.dc-shop.com/$req_url`)
return next.handle(req);
And in your Main Module:
export const httpInterceptorProviders = [
provide: HTTP_INTERCEPTORS, useClass: RequestInterceptor, multi: true,
}
@NgModule(
providers: [...,httpInterceptorProviders]
)
If you want to config your prefix url in different environment:
Your can define it in your environment.xx.ts
under /src/environments
And Define the build config in angular.json
....
"configurations":
"api":
....
"fileReplacements": [
"replace": "src/environments/environment.ts",
"with": "src/environments/environment.api.ts"
]
....
...
And when your build your app ,
just add configuration
ng build --configuration=api
Good Luck!
Better would be If you provide example too.
