Question

When I try to import node.js module in Typescript like this:

import co = require(\'co\');
import co from \'co\';

without providing type definit

Answer 1

I got an error when I used the "Stubbing type definitions" approach in Tim Perry's answer: error TS2497: Module ''module-name'' resolves to a non-module entity and cannot be imported using this construct.

The solution was to rework the stub .d.ts file slightly:

declare module 'module-name' {
  const x: any;
  export = x;
}

And then you can import via:

import * as moduleName from 'module-name';

Creating your own stub file lowers the barrier to writing out real declarations as you need them.
