TS interfaces?

Expected Behaviour

I wonder why this module doesn’t export any TS interfaces (LoaderOptions).

import { LoaderOptions } from 'ts-loader'

Actual Behaviour

Just js code.

So I think it’s as simple as adding declaration: true to the tsconfig.json. Want to try and report back? If it’s just that then pr with that change and we’re done!

Heyo! I have the same problem. I’m using awesome latest TS 2.9 for type checking js files and with that having type safe configs for webpack, jest etc. right now I have to write my own ambient type definitions for interface LoaderOptions

webpack.config.js

// @ts-check

/**
 * @type {Partial<import('ts-loader').LoaderOptions>}
 */
const tsLoaderOptionsRules = {
  configFile: tsConfig,
  transpileOnly: true
}

/**
 * @type {(env:{production?:boolean})=>import('webpack').Configuration}
 */
const config = (env) => {

  return {
    module: {
      rules: [
        {
          include: resolve(__dirname, 'src'),
          test: /\.tsx?$/,
          loader: 'ts-loader',
          options: tsLoaderOptionsRules
        }
      ]
    },
}

instead I would like to use definitions, which you already have in codebase, just need to be shipped as ambient types with your package. I’m definitely up to sending a PR, if you can point me in right direction.

cheers !
