MutationDefinition type

The half of a mutation that describes the write itself, fordefineMutation: its identity, the write, and its policy. Lifecycle hooks are not part of it. They belong to the controller that runs the mutation and go to createMutation(ctx, def, hooks).

Signature:

type MutationDefinition<V, R> = Pick<MutationSpec<V, R>, 'mutate' | 'concurrency' | 'retry' | 'retryDelay' | 'meta'> & {
  id: string;
};
