How do I implement authentication in a Next.js app using GraphQL?

To implement authentication in a Next.js app using GraphQL, you can use libraries like Apollo Client for GraphQL queries and JWT for token management. First, set up your GraphQL server to handle authentication.

What libraries do I need to install for this?

You'll need to install apollo-client, graphql, and jsonwebtoken. You can do this using npm or yarn.

Can you provide a code example for the login mutation?

Sure! Here's a simple example of a login mutation:

mutation Login($email: String!, $password: String!) {
  login(email: $email, password: $password) {
    token
    user {
      id
      email
    }
  }
}

You can call this mutation from your Next.js component using Apollo Client.

How do I store the JWT token after login?

You can store the JWT token in local storage or a cookie. For example, after a successful login, you can do:

localStorage.setItem('token', token);

This way, you can access it later for authenticated requests.
