globals.d.ts

We discussed global vs. file modules when covering projects and recommended using file based modules and not polluting the global namespace.

Nevertheless, if you have beginning TypeScript developers you can give them a globals.d.ts file to put interfaces / types in the global namespace to make it easy to have some types just magically available for consumption in all your TypeScript code.

For any code that is going to generate JavaScript we highly recommend using file modules.

• globals.d.ts is great for adding extensions to lib.d.ts if you need to.
• It’s good for quick declare module "some-library-you-dont-care-to-get-defs-for"; when doing TS to JS migrations.
