Send http request before sending other http requests angular 2

Question

I need to get jwt token via http module then make other requests with this token in header. How I can make delay of app initialization till token get request resolved?

Answer 1

this.http.get(...)
.map(response => response.json())
.flatMap(response => this.http.get(...).map(response => response.json())
.subscribe(response => this.result = response);

You can use How to pass parameters rendered from backend to angular2 bootstrap method to delay app-initialization.
