How do I control what is stored in session.user ?

Question 💬

How do I specify what is stored in session.user after login ?
the authorize method uses a private mongodb to get my user and /login responds with an object containing username and name if the login is successful.

But when logging the session variable the user object contains email, image and name which only name is correct. email and image is null. How do I add username to the session.user so that I can use this later in my code ?

import NextAuth from 'next-auth'
import Providers from 'next-auth/providers'

export default NextAuth({
  // Configure one or more authentication providers
  providers: [
    Providers.Credentials({
      // The name to display on the sign in form (e.g. 'Sign in with...')
      name: 'Credentials',
      // The credentials is used to generate a suitable form on the sign in page.
      // You can specify whatever fields you are expecting to be submitted.
      // e.g. domain, username, password, 2FA token, etc.
      credentials: {
        username: { label: "Username", type: "text", placeholder: "jsmith" },
        password: {  label: "Password", type: "password" }
      },
      async authorize(credentials, req) {
        // You need to provide your own logic here that takes the credentials
        // submitted and returns either a object representing a user or value
        // that is false/null if the credentials are invalid.
        // e.g. return { id: 1, name: 'J Smith', email: '[email protected]' }
        // You can also use the `req` object to obtain additional parameters
        // (i.e., the request IP address) 
        console.log("authorize")
        const res = await fetch(`${process.env.SERVER_DEV}/api/login`, {
          method: 'POST',
          body: JSON.stringify(credentials),
          headers: { "Content-Type": "application/json" }
        })
        const user = await res.json()
        console.log(user)
        // If no error and we have user data, return it
        if (res.ok && user) {
          return user
        }
        // Return null if user data could not be retrieved
        return null
      }
    })
  ],
  // A database is optional, but required to persist accounts in a database
  //database: process.env.MONGODB_URI,
})

No, I am afraid I cannot help regarding this

Using the jwt and session callbacks https://next-auth.js.org/configuration/callbacks

I've got that working but how do you do it in typescript?

It gives me an error whenever I want to use my new attributes, you can see this in my issue #2498
