load external file on service

[marc]

Hi all,

I have a question for you. I should load an external file, a JSON file, containing environment variables.

For example:

export class ClientService {
 ...
 checkMail(...): any {

 return this.http.post(`${this.conf.hostServer}/api/otp`, ...)

 }

In this case I have this.conf.hostServer that must be read from another class.

@Injectable()
export class ConfigService {
 env: string
 constructor(public http: HttpClient) {
 this.setSocketServer();

 }
 setSocketServer() {
 return new Promise<boolean>((resolve: (a: boolean) => void): void => {
 this.http.get('./config.json').pipe(map((x: any) => {
 this.env = x.env;
 resolve(true);
 }))
 .subscribe();
 });
 }
}

In this way I have in my ClientService the correct variables but I have to wait in my components that they are ready.
How can I do this ?

I saw that is present another way using APP_INITIALIZE but I don't like it for this case.

What do you suggest me ?


Thanks.

load it using your basic

const typeDefs = require("./config");
