Frequently Asked Questions

What is GraphQL?

GraphQL is a query language for APIs developed by Meta. Instead of multiple REST endpoints, a single endpoint accepts typed queries that specify exactly what data the client needs — reducing over-fetching and under-fetching.

Does formatting change the GraphQL query behavior?

No. Formatting only affects whitespace and indentation. The server processes the formatted and unformatted query identically.

What is the difference between a query, mutation, and subscription in GraphQL?

Queries read data (like GET). Mutations write or update data (like POST/PUT/DELETE). Subscriptions establish a persistent connection for real-time data updates pushed from the server.
