ant-design: Type error: Cannot find name 'ResizeObserver'.

The temporary fix is putting following interface to your typings/index.d.ts:

interface ResizeObserver {
  observe(target: Element): void;
  unobserve(target: Element): void;
  disconnect(): void;
}

Temp fix:

1. Open: node_modules/antd/lib/input/TextArea.d.ts
2. Insert import: import ResizeObserver from 'resize-observer-polyfill';

Fixed by resize-observer-polyfill@1.5.1 https://github.com/que-etc/resize-observer-polyfill/pull/45

https://github.com/que-etc/resize-observer-polyfill/pull/45 fixes the polyfill’s types, but antd itself can be fixed by adding a /// <reference types="resize-observer-polyfill" /> to the file (to make the dependency on the global patch explicit), as an alternative.
