How does the GraphQL Formatter work?

Prettier parses the incoming document, walks the abstract syntax tree, and rewrites each node according to GraphQL formatting conventions. Fragments, inline selections, and directive chains remain intact but become easier to scan.

When syntax errors appear, the formatter halts with a descriptive message so mismatched braces or missing fields are obvious. Built-in samples and instant copy keep experimentation fast.

What is GraphQL?

GraphQL is a schema-driven query language that lets clients request exactly the data they need from a single endpoint. Type-safe contracts power product teams, but documents can become sprawling as features grow.

Regular formatting keeps intents clear, supports compliant documentation, and prevents subtle bugs in multi-team environments.

Usage scenarios and best practices

Add the formatter to a pre-commit hook or docs build to keep API handbooks consistent and approachable for new teammates.

Use it when publishing examples to dashboards, design systems, or customer-facing docs so the contract always looks production-grade.

Frequently Asked Questions

Does it handle both SDL and operations in the same document?

Yes. Queries, mutations, subscriptions, and schema definitions can live side by side and the parser applies the correct rule set to each block.

Can I automate formatting inside CI?

Copy the output into your repository or run Prettier with matching settings in your pipeline so every merge request respects the same style.
