GraphQL Formatter

GraphQL Formatter formats GraphQL queries to a standard, readable style using a parser-driven approach. It accepts raw queries and produces a clean, consistent output suitable for code reviews and documentation.
Conceptually, the tool parses input into an AST and prints it with configurable rules such as indentation, line length, and optional field sorting. It can preserve comments to maintain context and annotations within the query. The result is deterministic formatting that reduces variances across developers and environments. This tool benefits frontend and backend teams, API integrators, QA engineers, and CI pipelines that require consistent GraphQL styling in PRs, tests, and shared examples.
Key value lies in standardization, reduced cognitive load during reviews, and faster onboarding for new contributors who need to understand query structure quickly. Core features include GraphQL-spec-compliant formatting, 2- or 4-space indentation, optional line wrapping, optional field sorting, and optional comment preservation, plus robust error reporting for syntax issues. Use cases include formatting ad-hoc queries, preparing examples for documentation, and enforcing a team-wide style via automated workflows.
