javascript - How to return an Observable in angular 4? -

i have method inside authprovider provider class:

getuser() {     return this.afauth.authstate.subscribe(user => {         return user;     }); }

i subscribe in different class, like:

this.authprovider.getuser().subscribe(user => console.log(user));

any ideas how return observable inside getuser() method?

your authstate observable. return authstate , subscribe within function. in function other work can use rxjs#map function.

getuser() : observable {     return this.afauth.authstate.map(...); }  ....  login() {    getuser().subscribe(user => {        return user;    }); }
