I am getting confused how to pass interface as parameter and set to http get ,post as globally
I written all http post, get, put, delete functions globally
public get_api(path: string, Interface) {
return this.http.get<Interface>(API_ENDPOINT + path);
}
Now I want to pass interface from another .ts file
this.http_global.get_api('user',Interface).subscribe(.....=>);
Can anyone helps !!!
Thanks In advance!!!!
You need to pass it as a generic type parameter, just as http.get does:
public get_api<T>(path: string) {
return this.http.get<T>(API_ENDPOINT + path);
}
this.http_global.get_api<Interface>('user').subscribe(.....=>);
If there is a clear relation between the string passed in an the result type, you might consider adding some overloads so the user doesn't have to specify the type all the type:
public get_api(path: 'user'): Observable<User>
public get_api<T>(path: string) : Observable<T>
public get_api<T>(path: string) : Observable<T> {
return this.http.get<T>(API_ENDPOINT + path);
}
this.http_global.get_api<Interface>('other').subscribe(.....=>);
this.http_global.get_api<('user').subscribe(.....=>); // Observable<User>
