recoil-sync window is not defined in NextJS using SSR

Hello!

I’m seeing this error when trying to use recoil-sync with NextJS. I assume it’s something to do with SSR.

index.js?46cb:352 Uncaught at getURL (file:///sites/node_modules/recoil-sync/cjs/index.js:2001:33)

Ah, my mistake!

Confirmed this is working

getURL: () => {
  return `http://localhost:3000${router.route}`;
},

Thank you for your patience in helping me with this.

currently the usage of refine should be

import {refine} from 'recoil-sync';
const {string} = refine;
