Hi all, my page will need to fetch data from remote server using REST services then based on the data to initialise my page. how do i make it to proceed following line only after data all arrived from server? thanks

I don’t think this is a good way to think about things in asynchronous networked applications. Instead be reactive:

this.foo = "sensible default";

http.get(url).subscribe((rsp) => {
  // only in here can you rely on the response
  this.foo = rsp.json();
});
