IntegrationsSSO and Google Auth

PullTheCode usesNextAuthto authenticate users. You can configure it in thesrc/app/api/auth/[...nextauth]/route.tsfile.

Setup

Make sure that you performed the following changes to the .env file:

NEXT_PUBLIC_WEBSITE_NAME=YOUR_WEBSITE_NAME
NEXT_PUBLIC_WEBSITE_URL=http://localhost:3000
NEXTAUTH_SECRET=RANDOM_ALPHANUMERIC_STRING_AT_LEAST_32_CHARACTERS_LONG
POSTGRES_PRISMA_URL=file:./dev.db

Create a new project in theGoogle Console
Go to [APIs & Services] > Credentials
Click [Configure Consent Screen]
Fill the form. You will be asked to provide a support email address, a product name, and the links for your privacy policy and terms of service, which you can generate with ChatGPT. Add userinfo.email & userinfo.profile to scope and add yourself as a test user. Confirm and save.
Go to [Credentials] > [+ Create Credentials] > [Oauth Client ID]
Select [Web Application]. Add http://localhost:3000 and https://your-website to Authorized JavaScript origins. Add http://localhost:3000/api/auth/callback/google and https://your-website.com/api/auth/callback/google to Authorized JavaScript origins. Click [Create]
Copy paste the Client ID in AUTH_GOOGLE_ID and Client Secret in AUTH_GOOGLE_SECRET to the .env file.
Go to [Oauth Consent Screen] > [Publish App], and submit for verification. Click [Prepare for verification] and fill the required information. Google will email you and you will have to reply to start the process. Your domain needs to be verified withGoogle Search Console. While you can already login with Google on localhost without issues, on production, it will work too but show a warning until you are verified (it usually takes a few days).
