Is it necessary to have typing/definiton files for every JS library you use in typescript?

An alternative to @Daniel Earwicker answer, as long as you are in a commonJS environment (and I guess you are using webpack) is to simply require the library using node require

const rn = require('react-notifications')

then use rn.NotificationContainer directly or import NotificationContainer = rn.NotificationContainer

It's not necessary. For your example, you create a file react-notifications.d.ts (you can call it anything you like as long as the extension is .d.ts but it makes sense to name it consistently):

declare module "react-notifications" {

    const NotificationContainer: any;
    const NotificationManager: any;
}

That's a near-minimal starting point. But you could go a little further and improve on those any declarations. They are a temporary cop-out.
