• Category: Operations
• Rule name: @graphql-eslint/possible-fragment-spread
• Requires GraphQL Schema: true ℹ️
• Requires GraphQL Operations: false ℹ️

A fragment spread is only valid if the type condition could ever possibly be true: if there is a non-empty intersection of the possible parent types, and possible types which pass the type condition.

This rule is a wrapper around a graphql-js validation function.
