nextauth.js is a powerful authentication library for next.js applications that supports various authentication providers and strategies. one of the features of nextauth.js is the ability to manage user sessions using json web tokens (jwt). the session callback allows you to customize the session object that is returned to the client.

in this tutorial, we'll cover how to use the jwt session callback to update the user session with custom user data. here’s how to do it step-by-step:

step 1: install nextauth.js

if you haven't already set up nextauth in your next.js project, you can install it using npm or yarn:

```bash
npm install next-auth
or
yarn add next-auth
```

step 2: set up api route for authentication

create an api route for authentication. in your next.js project, create a new file at `pages/api/auth/[...nextauth].js`:

```javascript
import nextauth from "next-auth";
import providers from "next-auth/providers";

export default nextauth({
providers: [
providers.google({
clientid: process.env.google_client_id,
clientsecret: process.env.google_client_secret,
}),
// add other providers as needed
],
callbacks: {
async jwt(token, user) {
// this callback is called whenever a jwt is created or updated.
if (user) {
// if user exists (on sign in), add user info to the token
token.id = user.id;
token.email = user.email;
token.name = user.name;
}
return token;
},
async session(session, token) {
// this callback is called whenever a session is checked.
// here, you can add custom properties to the session object

session.user.id = token.id; // add user id to the session
session.user.email = token.email; // add user email to the session
session.user.name = token.name; // add user name to the session

return session;
},
},
});
```

step 3: configure environment variables
