node.js - Extends an NPM module class with no typings from TypeScript -

-

i wanted experiment mobx-firebase-store in typescript code. has no typings uses javascript classes.

i tried convert chatstore.js code imports mobxfirebasestore class:

import mobxfirebasestore 'mobx-firebase-store';

and later extends it:

export default class messagestore extends mobxfirebasestore {

since there no types, tried using trick make library declared any

typings install mobx-firebase-store=common~any --save

then:

import * mobxfirebasestore 'mobx-firebase-store';

but line:

export default class messagestore extends mobxfirebasestore {

has following errors:

ts2507:type 'any' not constructor function type. ts4020:extends clause of exported class 'messagestore' has or using private name 'mobxfirebasestore'.

what quickest , easiest way get past these errors , able extend class in similar way being done here babel?
