ReferenceError: document is not defined; SSR.

[MorpheusFT]

const doc = document, win = window, div = doc.createElement('div'), { filter, indexOf, map, push, reverse, slice, some, splice } = Array.prototype;

I render it server side first, then later hydrate on the client side, which is probably why your component fails.

If you are using next js you just have to tell next to import and render the component only on the client and not to apply ssr for that component, this for libraries that for example run only in the browser. I recommend these links

For Next.js, this seems to work for me:

const ResizePanel = dynamic(() => import('react-resize-panel'), { ssr: false });

Would be nice to support SSR I think? Even if it's non-functional and just does the basic DOM element wrapping or whatever.
