Property 'Collection' does not exist on type 'typeof Mongo'

Hi there!

I’m getting a typescript console warning when compiling my app.

Property 'Collection' does not exist on type 'typeof Mongo'.

My code:

import { Mongo } from 'meteor/mongo';
import MongoCollection from '../../lib/MongoCollection';

class game extends MongoCollection {
  public collection: any;
  constructor() {
    this.collection = new Mongo.Collection('games');

export let Game = new game();

the app works, it’s just the typescript warning.

any help is appreciated. thanks
