GraphQL mutation
A GraphQL mutation is an operation that requests a change to server-side data or state and may return selected fields resulting from that change.
Quarkus in Action
A GraphQL mutation is a GraphQL operation that can add or modify data and may return data with the update.
- How it is used
- Uses mutations to add or modify data while returning selected fields from the resulting object.
- How deep it goes
- Defines operation semantics and demonstrates input, field selection, response echoing, and database verification without covering advanced GraphQL features.
- Examples
- Demonstrates a register mutation that creates a fleet car, echoes selected fields, and verifies persistence with a cars query.
- What you can do after
- Apply it via GraphiQL by supplying mutation arguments, selecting response fields, executing the operation, and checking the resulting data.

A GraphQL mutation is an operation that requests a state-changing action from a GraphQL server and can return selected resulting fields.
- How it is used
- Uses a state-changing operation to update a board game's name through a GraphQL API.
- How deep it goes
- Walks through token setup, mutation execution, and database verification, but does not detail server-side mutation implementation.
- Examples
- Demonstrates renaming Die Macher and assigning a revised name to Axis & Allies.
- What you can do after
- Operate/configure BananaCakePop to authorize and execute a mutation, then verify the saved change with a query.
