Files with only type declarations do not get declaration files generated

[jamiebuilds]

Test repo: https://github.com/thejameskyle/test-awesome-ts-loader

If I have a file like this:

export interface a {}

And I run with these options:

{
  test: /\.tsx?$/,
  loader: 'awesome-typescript-loader',
  options: {
    declaration: true,
    declarationDir: './types',
  },
},

It will not create a file.

As soon as I add a value it will though.

  export interface a {}
+ export const b = {};

I'm having a similar problem, but can't resolve it by adding an "export const WORKAROUND = 'workaround'". In addition, I need to import the const, and use it somewhere in a .ts file. I've put together a minimal project that shows this:

Having the same issue on 3.4.1

Using regular tsc works fine though.

@s-panferov any pointers as to where to look in the code to fix this?

Another test case: https://github.com/sqwk/declaration-test (Previously for a typescript bug—turns out tsc works fine …)

I also have the same error, awesome-typescript-loader version 5.2.1 doesn't export my files containing only interface declarations :(

Same issue here. Is there any update on this?

[dolanmiu]

The last proper code commit was in Jul 2018, so probably no update on this. Maybe this project is dead?

For anyone wanting a quick fix until ATL gets updated, ts-loader ended up working fine for me.
