Actually, the typings you are shipping seem to be incorrect in general as you are not exporting the class instance correctly.

See https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/html-webpack-plugin/index.d.ts

Could you please be a little bit more concrete?

Compare https://github.com/jantimon/html-webpack-plugin/blob/master/typings.d.ts with https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/html-webpack-plugin/index.d.ts

The typings shipped with this package are mostly useless without the class export.

Or we can rename typings.d.ts to index.d.ts according to https://www.typescriptlang.org/docs/handbook/declaration-files/publishing.html

Adding a types property is advised even if it is named index.d.ts

But we don’t export the typings - we use the typescript salsa feature jsdocs as typings.

The typings.d.ts is just an internal helper for the html-webpack-plugin.

However the typescript team is working on generating definition files from salsa files.

Once that works we will provide a typing file which we will link from the package.json to the type file

@jantimon does that mean you aren't interested in merging #1132? I opened that precisely so that this project would export typings that are usable in TS based webpack configs.

The main idea was to prevent bugs by using types from webpack.

If the changes you did on #1132 are enough to provide external typings then I am happy to make them public as types
