graphql-schema-utilities

A CLI tool for merging GraphQL schema files and validating operations against the merged schema, developed by AWS Labs. Version 1.1.8 is the latest stable release. It supports custom validation rules, glob patterns for schema and operation files, and TypeScript types. Unlike graphql-tools which is more comprehensive, this tool focuses specifically on schema merging and operation validation with a simple CLI interface. The package includes directives merging as an option and provides exit codes for CI integration.
