Typescript - Can I "bolt-on" types from one module to another module?

Background

Node has a package called path which has a type definitions file associated with it in the @types/node npm package. Someone made a client-side package called path-browserify which has the same api but has no types.

Question

Can I bolt on the @types/node types for path to use with path-browserify? Basically I want to use types in one place with a different name. I've tried this:

// types.d.ts
declare module 'path-browserify' {
  export {default} from 'path'
}

// usage.ts
import * as path from 'path-browserify'

const joined = path.join('/', 'file');
// ^ COMPILE ERROR: join not found

const joined = path.default('/', 'file'); 
// ^ RUNTIME ERROR: default not found

But I'm unable to access the api correctly. Is there a better way to use these type definitions? preferably without copying the path api.

browserify typescript node.js

You look like you're on the right track. Can you do something like this?

declare module 'path-browserify' {
  import path from 'path'
  export default path
}

As for your usage, try the following (rather than using * as syntax)

import path from 'path-browserify'
path.resolve(...)

As an aside, does the path module even have a default export ... ?
