To be able to use the package in my library (which is built as a dual ESM/CJS lib via `tsup`) , I had to resort to this hack: ```ts import ReactDiffViewer from "react-diff-viewer"; const DiffViewer: typeof ReactDiffViewer = (ReactDiffViewer as any).default ? (ReactDiffViewer as any).default : ReactDiffViewer; ``` For more information: https://arethetypeswrong.github.io/?p=react-diff-viewer%403.1.1
