Hooks
Refer to the TypeScript reference page for information about the types and interfaces referenced below.
These hooks are used internally by React Query Builder and exported for use in custom components.
State access
React Query Builder uses Redux within a custom React context to manage state without interfering with existing Redux stores.
useQueryBuilderQuery
Retrieves the complete, current query object for the nearest ancestor QueryBuilder component.
The optional parameter should only be used when retrieving a query object from a different QueryBuilder than the nearest ancestor. It can be either a complete props object as passed to a custom component or any object matching the interface { schema: { qbId: string } }.
function useQueryBuilderQuery(props?: { schema: { qbId: string } }): RuleGroupTypeAny;
As a React hook, this function must follow the appropriate rules. It provides access to the current query during the render phase, not in event handlers.
To access the current query from an event handler, use props.schema.getQuery() instead.
useQueryBuilderHistory
Records undo/redo history for the query builder with the given qbId, and returns controls for navigating it. Available from the react-querybuilder/history entry point.
Unlike the other hooks in this section, it does not need to be rendered beneath a QueryBuilder, which is what allows external toolbars and keyboard shortcut handlers to drive a query builder's history.
function useQueryBuilderHistory(
qbId: string,
options?: { maxHistory?: number; coalesceMs?: number }
): {
undo: () => void;
redo: () => void;
clear: () => void;
canUndo: boolean;
canRedo: boolean;
past: RuleGroupTypeAny[];
future: RuleGroupTypeAny[];
};
See Undo/redo for the full guide.
useQueryBuilderSelector
Prefer useQueryBuilderQuery if you only need the query object for the nearest ancestor QueryBuilder component.
Returns the current query from the Redux store when used with getQuerySelectorById (see example below).
function useQueryBuilderSelector(selector: (state: RqbState) => RuleGroupTypeAny): RuleGroupTypeAny;
Example:
const CustomValueEditor = (props: ValueEditorProps) => {
const fullQuery = useQueryBuilderSelector(getQuerySelectorById(props.schema.qbId));
// Here you can use utilities like `findPath(getParentPath(props.path), fullQuery)`.
// This allows you to, for example, inspect the parent group of the current rule.
// You can then count sibling rules, check for unique `field` selections, etc.
// That information can be used for validation, information to the user, or
// anything else in your render function.
};
getDispatchQueryById
Not a hook, but the write-side counterpart to the selectors above. Returns the dispatchQuery function for the mounted query builder with the given qbId, or undefined if no such query builder is mounted.
function getDispatchQueryById(qbId: string): DispatchQueryFn | undefined;
Updating a query through this function is equivalent to a user edit: the query is applied to the internal store and the query builder's onQueryChange callback fires, so it works whether the query builder is controlled or uncontrolled. That makes it possible to drive a query builder from outside its own component tree—an external toolbar, a keyboard shortcut handler, or the undo/redo controls in react-querybuilder/history, which use it to apply restored queries.
Requires an explicit qbId prop, since automatically generated identifiers are not discoverable from outside the component.
const dispatchQuery = getDispatchQueryById('main');
dispatchQuery?.(add(currentQuery, { field: 'firstName', operator: '=', value: '' }, []));
useQueryManager
Subscribes to a QueryManager and returns its current query alongside the manager itself, re-rendering whenever the query changes. Returns a [query, manager] tuple.
function useQueryManager<RG, F, O, C>(
manager: QueryManager<RG, F, O, C>
): [RG, QueryManager<RG, F, O, C>];
function useQueryManager<RG, F, O, C>(
query?: RG,
options?: QueryManagerOptions<F, O, C>
): [RG, QueryManager<RG, F, O, C>];
Unlike every other hook in this section, useQueryManager does not use Redux and does not need to be rendered beneath a QueryBuilder. QueryManager maintains its own state, so queries managed this way are invisible to useQueryBuilderQuery, useQueryBuilderSelector, useQueryBuilderHistory, and getDispatchQueryById. Use it to build a headless or fully custom interface; it is not a replacement for the QueryBuilder component.
Pass an existing manager to control its lifetime yourself:
const qm = useMemo(() => new QueryManager(initialQuery, { fields }), []);
const CustomUI = () => {
const [query] = useQueryManager(qm);
// ...
};
Or let the hook create one. The manager is created on the first render and never recreated, so query is an initial value and options are captured once—later changes to either argument are ignored:
const CustomUI = () => {
const [query, qm] = useQueryManager(initialQuery, { fields });
return (
<>
<button onClick={() => qm.add(qm.createRule())}>Add rule</button>
<pre>{JSON.stringify(query, null, 2)}</pre>
</>
);
};
Since the manager is stable, its methods are safe to call from event handlers and to use in dependency arrays. A batch triggers a single re-render regardless of how many changes it contains, and mutations that resolve to a no-op trigger none.
To change the configuration after the first render, call reconfigure on the manager. The hook subscribes to the manager's config version in addition to its query, so a reconfiguration re-renders the component even though the query object is unchanged. A reconfigure call that changes nothing is a no-op, so an effect like the one below is safe to run on every render of a component whose translations object is rebuilt each time.
useEffect(() => {
qm.reconfigure({ translations });
}, [qm, translations]);
Component logic
The core logic of each component is encapsulated in a reusable hook. Each main component is little more than a call to its respective hook plus the JSX that uses the properties returned from that hook. This enables creating a custom presentation layer without copying logic code from the default components.
The @react-querybuilder/native package demonstrates this concept well. It calls the hooks from its own query builder, rule group, and rule components, but nests the sub-components within React Native View elements instead of HTML div elements used by react-querybuilder components.
useRule
Called by the Rule component. See source code for returned properties.
function useRule(props: RuleProps): {
// See source code for returned properties
};
The configuration-dependent half of its result—field data, operators, value editor type, value list, value sources, match modes, and validation result—is derived by the framework-agnostic deriveRuleContext utility from @react-querybuilder/core. QueryManager.getRuleContext() calls the same utility, so non-React implementations resolve rules identically. Its classNames and outerClassName come from the equally framework-agnostic deriveRuleClassNames/deriveRuleOuterClassName.
useRuleGroup
Called by the RuleGroup component. See source code for returned properties.
function useRuleGroup(props: RuleGroupProps): {
// See source code for returned properties
};
Its classNames and outerClassName come from deriveRuleGroupClassNames/deriveRuleGroupOuterClassName, and its combinator resolution from getRuleGroupCombinator (see QueryManager.getRuleGroupContext()).
useValueEditor
Called by the ValueEditor component. Accepts the same ValueEditorProps as the component and returns an object with these properties: the value as an array, a multi-value handler, a processed version of the parseNumbers prop, and the classname(s) to be applied to each editor in editor series.
function useValueEditor(props: ValueEditorProps): {
valueAsArray: any[];
multiValueHandler: (val: string, idx: number) => void;
parseNumberMethod: ParseNumberMethod;
valueListItemClassName: string;
};
This hook updates the value as a side effect when these conditions are true:
skipHookisfalse(the value editors in the compatibility packages set this totrueto avoid infinite loops)inputTypeis"number"operatoris something other than"between","notBetween","in", or"notIn"valueEditorTypeis not "multiselect"valueis an array or a string containing a comma (,) and at least one non-whitespace character on either side.
If all of these conditions are met, handleOnChange will be called with the first element of the array, or any characters before the first comma if value is a string.
Everything except that side effect is derived by the framework-agnostic value editor utilities from @react-querybuilder/core, so an implementation in another framework can reuse the logic without reimplementing it.
useValueSelector
Called by the ValueSelector component. Returns the given value as an array (unchanged if already an array) and a memoized change handler.
function useValueSelector(
props: Pick<ValueSelectorProps, 'handleOnChange' | 'listsAsArrays' | 'multiple' | 'value'>
): {
onChange: (v: string | string[]) => void;
val?: string | any[];
};
useSelectElementChangeHandler
Used by the ValueSelector component. Returns a memoized change handler designed specifically for HTML <select /> elements.
function useSelectElementChangeHandler(props: {
multiple?: boolean;
onChange: (v: string | string[]) => void;
}): (e: ChangeEvent<HTMLSelectElement>) => void;
useShiftActions
Used by the ShiftActions component. Generates shiftUp and shiftDown methods to move a rule/group up or down in the query hierarchy, plus shiftUpDisabled/shiftDownDisabled to indicate whether either button should be disabled (shiftUpDisabled is true for the first rule/group in the root group; shiftDownDisabled is true for the last rule/group in the root group).
function useShiftActions(
props: { path: Path } & Pick<Schema, 'combinators' | 'dispatchQuery' | 'getQuery'>
): {
shiftDown: () => void;
shiftDownDisabled: boolean;
shiftUp: () => void;
shiftUpDisabled: boolean;
};
useStopEventPropagation
Used by the default Rule and RuleGroup components to prevent default behavior and stop event propagation (e.g., a MouseEvent after clicking a <button>). Takes a function that accepts a MouseEvent and context parameters, then returns a new function that calls event.preventDefault() and event.stopPropagation() before calling the original function with the same arguments.
function useStopEventPropagation(
method: (event: React.MouseEvent, context: any) => void
): (event: React.MouseEvent, context: any) => void;
This hook is not used in RuleNative and RuleGroupNative—the Rule and RuleGroup components for @react-querybuilder/native.
useQueryBuilder
Returns everything needed to render a QueryBuilder component. Internally, this hook passes the result of useQueryBuilderSetup to useQueryBuilderSchema and returns the result of useQueryBuilderSchema. The returned object combines the results of useQueryBuilderSchema and useQueryBuilderSetup (see below).
As with useQueryBuilderSchema, this Hook must be called from a descendant component of QueryBuilderStateProvider. See QueryBuilder source code for an example.
This hook is unlikely to be necessary unless you're reimplementing the entire QueryBuilder component structure.
useQueryBuilderSetup
Called by the internal component rendered by QueryBuilder. Merges props and context values with the defaults and generates actions.
This hook is unlikely to be necessary unless you're reimplementing the entire QueryBuilder component structure.
function useQueryBuilderSetup(props: QueryBuilderProps): {
qbId: qbId.current;
rqbContext: ReturnType<typeof useMergedContext>;
fields: OptionList<Field>;
fieldMap: Record<string, Field>;
combinators: OptionList<Combinator>;
getOperatorsMain: (field: string) => OptionList<Operator>;
getRuleDefaultOperator: (field: string) => string;
getValueEditorTypeMain: (field: string, operator: string) => ValueEditorType;
getValueSourcesMain: (field: string, operator: string) => ValueSources;
getValuesMain: (field: string, operator: string) => OptionList;
getRuleDefaultValue: (rule: RuleType) => any;
getInputTypeMain: (field: string, operator: string) => string;
createRule: () => RuleType;
createRuleGroup: () => RuleGroupTypeAny;
};
useQueryBuilderSchema
Called by the internal component rendered by QueryBuilder. Returns everything needed to render a wrapper element (e.g., <div>) and the root RuleGroup element based on the provided props and the result from useQueryBuilderSetup.
This Hook must be called from a descendant component of QueryBuilderStateProvider. See QueryBuilder source code for an example.
This hook is unlikely to be necessary unless you're reimplementing the entire QueryBuilder component structure.
function useQueryBuilderSchema(
props: QueryBuilderProps,
setup: ReturnType<typeof useQueryBuilderSetup>
): QueryBuilderProps & {
actions: QueryActions;
rootGroup: RuleGroupTypeAny;
rootGroupDisabled: RuleGroupTypeAny;
queryDisabled: boolean;
rqbContext: ReturnType<typeof useMergedContext>;
schema: Schema;
translations: TranslationsFull;
wrapperClassName: string;
dndEnabledAttr: 'enabled' | 'disabled';
inlineCombinatorsAttr: 'enabled' | 'disabled';
combinatorPropObject: Pick<RuleGroupProps, 'combinator'>;
};
Other utilities
useAsyncOptionList
Augments a ValueSelectorProps or ValueEditorProps object with async option loading.
import { type UseAsyncOptionListParams, useAsyncOptionList } from 'react-querybuilder';
const useAsyncOptionListParams: UseAsyncOptionListParams = {
getCacheKey: 'field',
loadOptionList: async (value, { ruleOrGroup }) => {
const response = await fetch(`/api/operators?field=${ruleOrGroup.field}`);
return response.json();
},
};
const AsyncOperatorSelector = (props: ValueSelectorProps) => {
const asyncProps = useAsyncOptionList(props, useAsyncOptionListParams);
return <props.schema.controls.valueSelector {...asyncProps} />;
};
const App = () => <QueryBuilder controlElements={{ operatorSelector: AsyncOperatorSelector }} />;
useMergedContext
Merges the values inherited from the nearest ancestor QueryBuilderContext.Provider with the current component's props. For controlClassnames, controlElements, and translations, options that are not defined through either context or props will fall back to the defaults.
function useMergedContext(props: QueryBuilderContextProps): QueryBuilderContextProps;
usePreferProp
Given a default value, a prop value, and a context value (all boolean or undefined), returns the first one that is not undefined in the order of (1) prop, (2) context, (3) default.
function usePreferProp(default: boolean, prop?: boolean, context?: boolean): boolean;
usePrevious
Returns the value of a prop or state variable from the previous render.
function usePrevious<T>(prop: T): T | null;
Internal
These hooks log error messages to the console in certain situations (only in "development" mode). They encourage correct usage of React Query Builder and aren't intended for use in custom components.
useControlledOrUncontrolled
Logs an error to the console if any of the following are true:
- Both
queryanddefaultQueryprops are defined. - The
queryprop is defined during one render and undefined in a subsequent render. - The
queryprop is undefined during one render and defined in a subsequent render.
useDeprecatedProps
Logs an error to the console if any of the following are true:
QueryBuilderis rendered withindependentCombinatorsprop (see Independent combinators)RuleGroupis rendered withcombinatororrulesprops (deprecated in favor ofruleGroup)Ruleis rendered withfield,operator, orvalueprops (deprecated in favor ofrule)
useReactDndWarning
Logs an error to the console if the enableDragAndDrop prop is true but the react-dnd and react-dnd-html5-backend dependencies are not loaded.
