graphql-clj

It rigorously validates GraphQL schemas and queries against the specification, ensuring correctness, as shown in the schema-validator and query-validator functions that throw errors on non-compliance.

Uses a Java-based parser for efficient parsing of schemas and queries, improving execution speed, which is highlighted in the 'What's new' section for version 0.2.

Supports caching of validated schemas and queries to enhance performance in repeated executions, demonstrated in the caching example where validated objects are memoized.

Version 0.2 introduced cleaner, separated APIs for schema and query parsing, making integration easier, as noted in the migration guide and usage examples.
