One way to avoid code duplication in GraphQL requests is to use query fragments.

  1. Define query fragments for commonly used fields in your GraphQL schema. This allows you to reuse these fragments in multiple queries or mutations without duplicating the code.


For example, you can define a fragment for a user that includes their ID, name, and email:

1
2
3
4
5
fragment UserInfo on User {
  id
  name
  email
}


  1. Use the spread operator (...) to include the fragment in your queries or mutations.


For example, you can use the UserInfo fragment in a query to fetch user information:

1
2
3
4
5
query getUser($userId: ID!) {
  user(id: $userId) {
    ...UserInfo
  }
}


By using query fragments, you can avoid duplicating code for common fields and improve the maintainability of your GraphQL requests.
