How to synchronise Angular2 http get?

Question

I understand using observable I can execute a method when the request is completed, but how can i wait till a http get is completed and return the response using in ng2 http

Answer 1

as you see, first callback waiting for a data from request and there you can go on with your logic (or use the third one)

example:

.. subscribe( data => { 
              this.value = data; 
              doSomeOperation;
              }, 
              error => console.log(error), 
              () => {console.log("Completed");
                      or do operations here..;
                    }
});
