Test case

Steps to reproduce

import { Injectable, NgZone } from ‘@angular/core’; import { AngularFireDatabase } from ‘angularfire2/database’; import { GoogleMapsAPIWrapper } from ‘@agm/core’; import { MapsAPILoader } from ‘@agm/core’; import * as GeoFire from ‘geofire’;

@Injectable() export class GeoService extends GoogleMapsAPIWrapper { dbRef: any; geoFire: any;

constructor(private db: AngularFireDatabase, private auth: AuthService) { const path = this.getDBRef(this.vehicleType); this.dbRef = this.db.list(path); this.geoFire = new GeoFire(this.dbRef.$ref); }

getDBRef = (type) => { const country = (this.auth.userInfo.country ? this.auth.userInfo.country : ‘India’); const returnDBRef = ${country}/${type.toLowerCase()}; return returnDBRef; };

}

Expected behavior

The geoFire instance should be created

Actual behavior

Runtime error while creating the following: this.geoFire = new GeoFire(this.dbRef.$ref);

The codebase for geofire has been updated to resolve this issue however a new build has not been deployed to npm. You could install straight from GitHub though with npm i firebase/geofire-js.

[jQrgen]

This works in firebase functions with node 8:

// Import
const geofire = require('geofire');

// Usage
const geoFireInstance = new geofire.GeoFire(ref);
