I use Meteor + Angular 2, and have a one question. To connect collection changes into view using Component’s Zone:

const Companies = new MongoObservable.Collection<Company>('companies')

constructor() {
   this.companies = Companies.find({}).zone();

And what if I need to select only one company? How to use findOne() method with zone()?



Maybe you could try to track for changes with Tracker.autorun and NgZone.
Not sure it is the best practice, but it works for me

import { Component, NgZone, OnInit, OnDestroy } from '@angular/core';
import { Tracker } from 'meteor/tracker';


export class companiesComponent implements OnInit, OnDestroy {
  companies: Companies;
  companyName: string;

  constructor(private zone: NgZone) {}

  ngOnInit() {
    this.companies = MeteorObservable.subscribe('companies-publication', this.joueurName).subscribe(
      () => {
        Tracker.autorun(() => {
 => {
            this.companyInformations = CompaniesCollection.findOne({ name: this.companyName });


Tracker.autorun allows you to run a function that depends on reactive data sources, in such a way that if there are changes to the data later, the function will be rerun:
