Double verification mails #423

Closed budasnorbi closed 2 years ago

budasnorbi commented 2 years ago

Hey, I would like to report an issue about reactStrictMode: true at Next.js.

I got this setting default to true when generated the project. When i successfully signed up i got two email address verification emails. After a suggestion to change reactStrictMode to false it worked the way it should and i only got one mail.

I used the EmailPassword recipe.

hey @budasnorbi thanks for the detailed issue.

As per react, their strict mode should call a few react hooks twice during development mode to catch unexpected side effects. This list doesn't include useEffect which is what we use to make a call to the backend to send the email verification email. Also this is only for development builds.

However, in nextjs, even useEffect is called twice - I'm not sure why. And again, this happens only in development mode.

Maybe try react strict mode on and make a production build - does it still send the email twice?

budasnorbi commented 2 years ago

Yes, i can confirm that. Strict mode works with production build. Got one mail.

rishabhpoddar commented 2 years ago

Sounds good. So i am closing this issue.
