How to add custom variables to OAuth session?

[jfljs]

Question 💬

Hello,

I am trying to use NextAuth for authentication. The idea is to let users login with socials of their choice e.g. FB, Twitter, Google

Upon logging in, I use the signIn callback to check for their profile details (if present), and also whether they are banned. I store their email received from the third-party sign in providers, and on-top of that, additional info e.g. last sign in, account statistics.

However, I want these information e.g. lastSignIn, postCount to also be visible in the session.

I know we can use the session callback to add values to the session but I am not sure how to get the information I've collected in the signIn callback and place it in the session, if that makes sense. I want to only check for these details once during the signIn callback.

Is my approach above correct? Or what is the correct way to login with third-party sites (Google, FB), and then verify that a user exists in system, and also get user-specific variables and place them in the session?

How to reproduce ☕️

What I have so far:

providers: [
GoogleProvider({
clientId: process.env.GOOGLE_CLIENT_ID,
clientSecret: process.env.GOOGLE_CLIENT_SECRET,
}),
// ...add more providers here
],
secret: process.env.AUTH_SECRET,
callbacks: {
async signIn({ user }) {
// check database for user credentials e.g. lastSignIn, postCount
return true
},
async jwt({ token, account }) {
// Persist the OAuth access_token to the token right after signin
if (account) {
token.accessToken = account.access_token
}
return token
},
async session({ session, token, user }) {
// Send properties to the client, like an access_token from a provider.
session.accessToken = token.accessToken
return session
}
}
