`graphql-query-tree` is a utility for parsing the `info` object passed to GraphQL resolvers into a query tree, enabling developers to inspect and extract useful information from GraphQL queries. It's designed for GraphQL developers who need to programmatically analyze query structures, such as checking if specific fields are requested, retrieving field arguments, or accessing child fields. The library supports fragments, inline fragments, and variable substitution, making it a practical tool for building efficient resolvers and implementing features like field-level access control or conditional data loading.
