I have a React Native app running on Firebase and I wanted to make it so that when you sign up you can only use a certain custom domain email like for example "johndoe@genius.com". How can I do this?

You can do frontend regex like
const emailRegex = /^[\w-\._\+%]+@(customDomain|customDomain1)\./
and before submitting that email in api call, you can test this
const onSubmitAPi = (text) => {
if(!(emailRegex.test(text))){
return null
}
//call api here
}
Hope it helps, feel free for doubts
