Answer

In NodeJS each file is a module. Declaring variables does not pollute the global namespace. So you don't need to use the good old IIFE trick to properly scope variables (and prevent global pollution / collision).

You would write:

  import * as express from "express";

  // import sub-routers
  import * as adminRouter from "./admin/admin";
  import * as productRouter from "./products/products";

  let router = express.Router();

  // mount express paths, any addition middleware can be added as well.
  // ex. router.use('/pathway', middleware_function, sub-router);

  router.use('/products', productRouter);
  router.use('/admin', adminRouter);

  // Export the router
  export = router;
