Please provide types for @open-wc/building-rollup

[lschierer]

After fighting with rollup's confusion over CommonJS versus Node ES modules for a while, I tried to write rollup's configuration file in typescript. I got blocked by the fact that @open-wc/building-rollup doesn't provide a declaration file.

rollup.config.ts:2:35 - error TS7016: Could not find a declaration file for module '@open-wc/building-rollup'. '/Users/luke/src/EvonyTKRTips/node_modules/.pnpm/@[email protected][email protected]/node_modules/@open-wc/building-rollup/index.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/open-wc__building-rollup` if it exists or add a new declaration (.d.ts) file containing `declare module '@open-wc/building-rollup';`

2 import { createBasicConfig } from '@open-wc/building-rollup';
                                    ~~~~~~~~~~~~~~~~~~~~~~~~~~

and my attempt at installing it

pnpm i --save-dev @types/open-wc__building-rollup
 ERR_PNPM_FETCH_404  GET https://registry.npmjs.org/@types%2Fopen-wc__building-rollup: Not Found - 404
