Frequently asked questions
- What does a GraphQL query formatter do?
- A GraphQL formatter normalizes spacing, lines, and indentation across fields, arguments, fragments, and directives, making queries legible and easy to review in pull requests.
- Does minifying a GraphQL query affect its execution?
- No. GraphQL execution engines parse AST tokens regardless of whitespace. Minified queries have identical semantics but smaller byte sizes for HTTP transmission.
- Can I format GraphQL mutations and subscriptions too?
- Yes. The formatter handles all standard GraphQL operations including query, mutation, subscription, fragment, and inline fragment definitions.
- How does it handle comments in GraphQL (#)?
- Standard hash (#) comments are preserved in formatted mode and cleanly stripped during minification.
- Is my GraphQL schema or private query sent anywhere?
- No. All parsing and formatting happens directly in your browser JavaScript memory.
