Displaying Meteor.user().username using Tracker React


Hello, I am fairy new to Meteor 1.3 + React.

I have been trying to display the Username of a Logged in user using Tracker React.
I have removed the autopublish packages.


import  React, {Component} from 'react'
import TrackerReact from 'meteor/ultimatejs:tracker-react';

export default class Sidebar extends TrackerReact(Component) {

    constructor() {
        this.state = {
            subscription: {
                users: Meteor.subscribe('users')

 render() {


Meteor.publish("users", function () {
    return Meteor.users.find();

I am getting a null object while console.log(Meteor.user()). However, I can see the current username using the Meteor DevTools for chrome.

What block of puzzle am I missing?
