Answer 1

You need to tell typescript that this function exists on window.external in order to use it. So :

interface External{
    notify: Function;
}

if (window.external.notify != undefined)
    window.external.notify("your message");

Answer 2

//notif.js

let notify = function(message) {
    alert(message);
}

//test.ts

declare function notify(message: string): any;
if(notify != undefined)
    notify("your message");

Make sure notif.js is loaded first.
