import { AngularFireDatabase, FirebaseListObservable } from "angularfire2/database-deprecated";

but when i compile i get and it cant help i dont know what to do where searching ect core.es5.js:1020 ERROR Error: Uncaught (in promise): Error: No provider for AngularFireDatabase! Error: No provider for AngularFireDatabase!

"angularfire2": "^5.0.0-rc.2", "core-js": "^2.4.1", "firebase": "^4.5.0",

Solution

  • In angularfire2": "^5.0.0-rc.2 you can't use FirebaseListObservable instead you will have to use 

    import { AngularFireDatabase } from 'angularfire2/database';

    and use it like this

    constructor(public af: AngularFireDatabase) {
  let restaurants = this.af.list('/path');
}
