copy keep angularfire list

Maybe

Object.assign   but sub itme only reference

So JSON.parse(JSON.stringify(theObject))

angular2 ionic2 angularfire2 json <-> object

authstat json <-> object

import { Storage } from '@ionic/storage';
import { FirebaseAuthState } from 'angularfire2';


// authstate  object -> json

this._auth.signInWithEmailAndPassword(this.loginForm.value.email, this.loginForm.value.password)
.then((authData: FirebaseAuthState ) => {
  this.storage.set('alluserinfo', JSON.stringify(authData));
});



//json -> authstate  object

this.storage.get('alluserinfo').then((t_value) => {
      let value: FirebaseAuthState;
      value = JSON.parse(t_value);
});

AngularFire ionic2 auth

Very Important !!

use subscribe

constructor(public af: AngularFire) {
    af.auth.subscribe((authstate) => {
        console.log(authstate);
        authstate == null ? logout() : login(authstate.auth.displayName);
    });
  }

And  Think change to Callback mode .............


==========
First :
   everyone use af.auth.getauth() , then check,  have value is login, null is not login.

But it's mistack. Reload page, Change page  AngularFire miss...... af.auth be free.
Only login page can get af.auth

Second:
  af.auth.subscribe ( ....... )   When auth check finish, run subscribe ( ..... )
This is real get auth. But Think login different First way........
