Better Auth•2w ago

How can I configure something like nextauth `callbacks.signIn`?

When user signin by apple or google oauth, I want to query user information from my exists database, and verify that the user, and return new user information to session in nextauth I can do something like: 
callbacks: {
          async signIn(params) {
            const { user, account, profile } = params
            console.log("user:", params.user, params)

            if (!user || !user.email || !account) {
              return false
            }
      
            let ourUser = await getUserByEmail(user.email!)
            if (!ourUser) {
                ourUser = await createUser(account.provider!, user, profile)
            }

            // old mtbird auth
            const myToken = signLogin(ourUser.id, user)
            res.setHeader('Set-Cookie', `t=${myToken}`);
            return true
          },
}
callbacks: {
          async signIn(params) {
            const { user, account, profile } = params
            console.log("user:", params.user, params)

            if (!user || !user.email || !account) {
              return false
            }
      
            let ourUser = await getUserByEmail(user.email!)
            if (!ourUser) {
                ourUser = await createUser(account.provider!, user, profile)
            }

            // old mtbird auth
            const myToken = signLogin(ourUser.id, user)
            res.setHeader('Set-Cookie', `t=${myToken}`);
            return true
          },
}
What should I do here?

This is what better auth does internally for you like creating a user and session even also validation as well. But you are looking to inspecting more you can hook in to databaseHook to trigger some actions before and after the user or session created.
