Re-exporting a type when the '--isolatedModules' flag is provided requires using 'exp-CodePudding

I have created multiple interfaces and want to ship them all from a common index.ts file as shown below:

--pages
------index.interface.ts
--index.ts

Now In my index.ts I am exporting something like:

export { timeSlots } from './pages/index.interface';

whereas my index.interface.ts look like this:

export interface timeSlots {
  shivam: string;
  daniel: string;
  jonathan: string;
}

Now when I try to do so, it says me:

Re-exporting a type when the '--isolatedModules' flag is provided requires using 'export type'.ts(1205)

Not sure why this error shows up, can someone help?

CodePudding user response：

You just need to use this syntax when re-exporting types:

export type { timeSlots } from './pages/index.interface';
//     ^^^^
// Use the "type" keyword

Or, if using a version of TypeScript >= 4.5, you can use the type modifier on the name instead:

export { type timeSlots } from './pages/index.interface';
//       ^^^^
// Use the "type" keyword
