Make a single object observable and reactive


I’m working with Angular2 and I’m trying to make a single object Observable.
For a list, it’s ok :

import { Component, OnInit, OnDestroy } from '@angular/core';

import { Observable } from 'rxjs/Observable';
import { Subscription } from 'rxjs/Subscription';

import { MeteorObservable } from 'meteor-rxjs';

import { Example } from '../../../../both/models/example.model';
import { Examples } from '../../../../both/collections/examples.collection';

import template from './example-list.component.html'

    selector: 'example-list',

export class ExampleListComponent implements OnInit {

    examples: Observable<Example[]>;

    public constructor() {

    ngOnInit() {
        this.examples = Examples.find({}).zone();

And then, I can loop on examples in the template side.

But how to deal with single object ?
How can i retrieve them from a collection and make each update reactive from a client to another ?

I can’t figure it with a “findOne”. This doesn’t work :

export class ExampleListComponent implements OnInit {

    example: Observable<Example>;

    public constructor() {

    ngOnInit() {
        this.example = Examples.findOne({});

What is the right way to do this ?
Thanks !!!
