How to re-export all types from module?

Question

I want to re-export all types in a module. Is there a way to achieve this?

I did try:

export type * from 'react-router-dom';

But it doesn't work:

Only named exports may use 'export type'. ts(1383)

Answer 1

Typescript 5.0 now has support for this:

export type * from "external-module"

//OR

export type * as ns from "external-module".

Update typescript and you’ll be able to!

Answer 2

First, you need to import the type as Types then export it like this way.

// your-module
import type * as Types from "external-module";
export { Types };

// Usage by the end user
import { Types } from "your-module";
let a:Types.Class;

hope it's helpful.
