How you retrieve specific data from backend in angular
The example route given by sololearn localhost:3002/flights/query/city1/city2 is not working for me.

You can do so by importing the { HttpClient } in your service.ts file
Inside the constructor invoke it like this
constructor(private http:HttpClient){
}
Then the method that does the job should make a get request to your url
Example:-
getData(){
return this.http.get(your_url)
}
Then in your app component you can map the data that the method returns.
