Next.js with Firebase Remote Config - firebase

Question

I was trying to integrate Google's Firebase Remote config into my Next.js app.
When following Firebase's docs, and just inserted the functions directly into my component's code block, like so:
const remoteConfig = getRemoteConfig(app);
I keep getting the following error when following their documentation:
FirebaseError: Remote Config: Undefined window object. This SDK only supports usage in a browser environment.

I understand that it happens since Nextjs is rendered server-side, so there's no window object yet, so here's my solution:
import {
fetchAndActivate,
getRemoteConfig,
getString,
} from 'firebase/remote-config';
const Home: NextPage<Props> = (props) => {
const [title, setTitle] = useState<string | null>('Is It True?');
useEffect(() => {
if (typeof window !== 'undefined') {
const remoteConfig = getRemoteConfig(app);
remoteConfig.settings.minimumFetchIntervalMillis = 3600000;
fetchAndActivate(remoteConfig)
.then(() => {
const titleData = getString(remoteConfig, 'trueOrFalse');
setTitle(titleData);
})
.catch((err) => {
console.log(err);
});
}
});
return <h1>{title}</h1>}
Basically, the important part is the if statement that checks if the window object exists, then it execute the Remote Config functions according to Firebase documents.
Also, it worked outside a useEffect, but I think that's probably a bad idea to leave it outside, maybe even it should have a dependency, can't think of one at the moment.
