Feature request: Custom function to generate the d.ts file

[jens-duttke]

After the latest update of style-loader and mini-css-extract-loader (where esModule defaults to true), the compilation does not work anymore.

I was able to fix that by replacing

import * as styles from './styles.module.scss';

by

import styles from './styles.module.scss';

But now the generated "styles.module.d.ts" file does not match, since TypeScript complains about the missing default export.
I would need to change that to:

declare const styles: {
	// My classes here
};

export default styles;

Would it make sense to implement a configuration option, which get's a list of all classes as parameter, and which returns a string, which is then used as content of the .d.ts file?

	{
	loader: 'dts-css-modules-loader',
	options: {
		banner: '// This file is automatically generated. Do not modify this file manually -- YOUR CHANGES WILL BE ERASED!',
		customDeclaration: function (classes) {
			let typings = 'declare const styles: {\n';

			for (const c of classes) {
				typings += `\t'${c}': string;\n`;
			}

			typings += '};\n\nexport default styles;\n';

			return typings;
		}
	}
},

Why not, good idea!

@jens-duttke you can use this option to customize end-of-line characters (issue #18)
