Mixing
Read a Object with AngularJS
I have an object created from a JSON
{"date": "11/21/2018", "nick": "abcd"}
When reading it with
const xUrl = 'https://xxxxxx.firebaseio.com/usuarios.json?orderBy="nick "';
return this.http.get (xUrl) .pipe (
map (res => {
return res;
console.log (res);
})
);
The result of console.log (res); is a Object :
-LRqtDl09Sc1J4K4IOln:
date: "11/21/2018"
nick: "abcd"
I need to know the number of returned results and if there are results, take the Nick field
Thank's

Object.keys({"date": "11/21/2018", "nick": "abcd"}).length
will allow you to check if any properties where passed back. So if the length is greater than 0 you have results and then you can check how many were actually passed. I hope I understood your question correctly.
