Properties

PropertyTypeDefault valueDescription
gcTime?numberundefinedThe time in milliseconds that an unused/inactive mutation remains in memory before it is garbage collected. Defaults to 5 * 60 * 1000 (5 minutes), or Infinity during SSR.
meta?Record<string, unknown>undefined-
mutationFn?(variables: TVariables, context: MutationFunctionContext) => Promise<TData>undefined-
mutationKey?readonly unknown[]undefined-
networkMode?"online" | "always" | "offlineFirst"'online'Controls whether a mutation is allowed to run based on the current network connectivity. See Network Mode for more information.
onError?(error: TError, variables: TVariables, onMutateResult: TOnMutateResult | undefined, context: MutationFunctionContext) => unknownundefined-
onMutate?(variables: TVariables, context: MutationFunctionContext) => TOnMutateResult | Promise<TOnMutateResult>undefined-
onSettled?(data: TData | undefined, error: TError | null, variables: TVariables, onMutateResult: TOnMutateResult | undefined, context: MutationFunctionContext) => unknownundefined-
onSuccess?(data: TData, variables: TVariables, onMutateResult: TOnMutateResult, context: MutationFunctionContext) => unknownundefined-
retry?| number | false | true | (failureCount: number, error: TError) => boolean0If false, failed mutations will not retry by default. If true, failed mutations will retry infinitely. If set to an integer number, e.g. 3, failed mutations will retry until the failed mutation count meets that number. If set to a function (failureCount, error) => boolean failed mutations will retry until the function returns false.
retryDelay?number | (failureCount: number, error: TError) => numberundefinedThis function receives a retryAttempt integer and the actual Error and returns the delay to apply before the next attempt in milliseconds. Defaults to a function that applies exponential backoff, capped at 30 seconds.
scope?MutationScopeundefined-
throwOnError?boolean | (error: TError) => booleanfalseWhether errors should be thrown instead of setting the error property. If set to true, all errors will be thrown to the nearest error boundary. If set to a function, it will be passed the error and should return a boolean indicating whether to throw the error (true) or return it as state (false).
