Understanding GraphQL
A quick guide to queries, schemas, and best practices
What is GraphQL?
GraphQL is a query language for APIs and a runtime for executing those queries with your existing data.
Queries vs Mutations
Queries fetch data; mutations modify server-side data. Use fragments to reuse fields across queries.
Schema Basics
Schemas declare types, fields, and their relationships. Strong typing helps clients discover available data.
Best Practices
Keep queries narrow, use aliases for clarity, and version schemas carefully to avoid breaking clients.
Common Errors
Watch for mismatched braces, undefined fragments, and incorrect field names. This formatter highlights syntax issues.
Tooling & Integrations
Combine formatted queries with linters, codegen, and IDE plugins for a smooth GraphQL developer workflow.
