Declaring an variable initialized in another file

I have some code that references a variable I know has already been declared in a file loaded before mine as in 

if (!Zotero.BetterBibTeX) { ... }

but this gets me "Cannot find name 'Zotero'". Is there a way to signal to the typescript compiler that "Zotero" is declared?

Well you need to import Zotero into your module. Declaring it as any does solve the compile error.. but that's not really the TypeScript way of importing modules.

// -------------------
// File ./zotero.ts
// -------------------
export class Zotero {
  someFunction() {
    // some code..
  }  
}

// -------------------
// File ./main.ts
// -------------------
import { Zotero } from "./zotero.ts";

// Now you can use Zotero.
let z = new Zotero();
z.someFunction();

You can add this at the top of the file where you're using Zotero:

declare let Zotero: {
    BetterBibTeX: any;
};

Then you can use if (!Zotero.BetterBibTeX) { ... } as you like.

If you don't want to have any type checking around the properties on Zotero, you can just declare it as an any type:

declare let Zotero: any;
