Expo + NextJs web ReferenceError: window is not defined

[cmaycumber]

I'm running into the following error: `ReferenceError: window is not defined on an app running expo and NextJS when Next is trying to use serverside rendering.

The faulty file is here: react-native-reanimated/lib/reanimated2/js-reanimated/JSReanimated.js:33:9.

After changing the following line of code from:

this.timeProvider = process.env.JEST_WORKER_ID
            ? { now: () => Date.now() }
            : window.performance;

to:

this.timeProvider = process.env.JEST_WORKER_ID || typeof window === 'undefined'
            ? { now: () => Date.now() }
            : window.performance;

It solved my error.

My question is my configuration wrong or is this just a bug with serverside rendering? Does adding this check affect anything else?

This is fixed in 5a449ec.

You can eject from managed workflow and use a patch-package to apply this commit for the time being or wait until the next expo release.
