What it checks

Ensures that all operation and fragment names are unique across the entire project. Duplicate names cause issues with persisted queries, code generation, and debugging.

Examples

file1.graphql

query GetUser {
  user {
    id
  }
}

# file2.graphql
query GetUser {
  # ❌ Error: Duplicate operation name 'GetUser'
  user {
    name
  }
}

Configuration

extensions:
  graphql-analyzer:
    lint:
      rules:
        uniqueNames: error # or warn, off

Note

This is a project-wide rule — it checks all documents together. It may be slower on large projects.
