Why Validate GraphQL Schemas?
Validating your GraphQL schema before deployment catches syntax errors, naming convention issues, and potential problems early. This prevents runtime errors and ensures your API follows GraphQL best practices.
FAQ
What does this validator check?
It validates schema syntax, brace matching, type definitions, field naming conventions, type annotations, and checks for common GraphQL patterns like Query and Mutation types.
Why do I get naming warnings?
GraphQL conventions suggest type names should be PascalCase (User, Post) while field names should be camelCase (getUsers, createPost). These are warnings, not errors.
Can I validate queries against a schema?
This tool validates schema definitions only. For validating queries against a schema, you'd need a full GraphQL runtime environment.
