How does OAuth2 work with GraphQL?

OAuth2 is an authorization framework that allows third-party applications to obtain limited access to user accounts on an HTTP service. In GraphQL, you can implement OAuth2 by using access tokens to authenticate requests.

What are the steps to implement OAuth2 in a GraphQL API?

To implement OAuth2 in a GraphQL API, you typically need to: 1) Register your application with the OAuth provider, 2) Implement the authorization code flow, 3) Use access tokens in your GraphQL requests, and 4) Validate tokens on the server.

Can you explain the authorization code flow?

Sure! The authorization code flow involves redirecting the user to the OAuth provider's login page, where they grant permission. The provider then redirects back to your application with an authorization code, which you exchange for an access token.

What libraries can I use to implement this in Node.js?

You can use libraries like 'passport' with 'passport-oauth2', 'graphql-shield' for permissions, or 'apollo-server' for setting up your GraphQL server.
