import QueryBuilder from 'react-querybuilder';
const fields = [
{ name: 'firstName', label: 'First Name' },
{ name: 'lastName', label: 'Last Name' },
{ name: 'age', label: 'Age' },
{ name: 'address', label: 'Address' },
{ name: 'phone', label: 'Phone' },
{ name: 'email', label: 'Email' },
{ name: 'twitter', label: 'Twitter' },
{ name: 'isDev', label: 'Is a Developer?', defaultValue: false }
];
const dom = <QueryBuilder fields={fields} onQueryChange={logQuery} />;
function logQuery(query) {
console.log(query);
}The default export of this library is the <QueryBuilder /> React component. Named exports include the <Rule /> component (for use in custom <RuleGroup /> implementations) and a utility function, formatQuery.
<QueryBuilder /> supports the following properties:
{id?: string, combinator: string, rules: ({field: string, value: any, operator: string} | {rules: ...[], combinator: string})[]}
The initial query, in JSON form (follows the same format as the parameter passed to the onQueryChange callback). id is optional. See the demo source for examples.
The array of fields that should be used. Each field should be an object with the following signature:
interface Field {
id?: string; // The field identifier (if not provided, then `name` will be used)
name: string; // REQUIRED - the field name
label: string; // REQUIRED - the field label
operators?: { name: string; label: string; }[]; // Array of operators (if not provided, then `getOperators()` will be used)
valueEditorType?: 'text' | 'select' | 'checkbox' | 'radio' | null; // Value editor type for this field (if not provided, then `getValueEditorType()` will be used)
inputType?: string | null; // Input type for text box inputs, e.g. 'text', 'number', or 'date' (if not provided, then `getInputType()` will be used)
values?: { name: string; label: string; }[]; // Array of values, applicable when valueEditorType is 'select' or 'radio' (if not provided, then `getValues()` will be used)
defaultValue?: any; // Default value for this field (if not provided, then `getDefaultValue()` will be used)
placeholder?: string; // Value to be displayed in the placeholder of the text field
}Field objects can also contain other data. Each field object will be passed to the appropriate OperatorSelector and ValueEditor components as fieldData (see the section on controlElements).
any
A "bucket" for passing arbitrary props down to custom components. The custom prop is passed to each and every component, so it's accessible anywhere in the QueryBuilder component tree.
{name: string, label: string}[]
The array of operators that should be used. The default operators include:
[
{ name: '=', label: '=' },
{ name: '!=', label: '!=' },
{ name: '<', label: '<' },
{ name: '>', label: '>' },
{ name: '<=', label: '<=' },
{ name: '>=', label: '>=' },
{ name: 'contains', label: 'contains' },
{ name: 'beginsWith', label: 'begins with' },
{ name: 'endsWith', label: 'ends with' },
{ name: 'doesNotContain', label: 'does not contain' },
{ name: 'doesNotBeginWith', label: 'does not begin with' },
{ name: 'doesNotEndWith', label: 'does not end with' },
{ name: 'null', label: 'is null' },
{ name: 'notNull', label: 'is not null' },
{ name: 'in', label: 'in' },
{ name: 'notIn', label: 'not in' }
];{name: string, label: string}[]
The array of combinators that should be used for RuleGroups. The default set includes:
[
{ name: 'and', label: 'AND' },
{ name: 'or', label: 'OR' }

showCombinatorsBetweenRules: boolean;
showNotToggle: boolean;
}(field: string) => { name: string; label: string; }[] | null
This is a callback function invoked to get the list of allowed operators for the given field. If null is returned, the default operators are used.
(field: string, operator: string) => 'text' | 'select' | 'checkbox' | 'radio' | null
This is a callback function invoked to get the type of ValueEditor for the given field and operator. Allowed values are "text" (the default if the function is not provided or if null is returned), "select", "checkbox", and "radio".
(field: string, operator: string) => string
This is a callback function invoked to get the type of <input /> for the given field and operator (only applicable when getValueEditorType returns "text" or a falsy value). If no function is provided, "text" is used as the default.
(field: string, operator: string) => { name: string; label: string; }[]
This is a callback function invoked to get the list of allowed values for the given field and operator (only applicable when getValueEditorType returns "select" or "radio"). If no function is provided, an empty array is used as the default.
string | ((fieldsData: Field[]) => string)
The default field for new rules. This can be a string identifying the default field, or a function that returns a field name.
(rule: Rule) => any
This function returns the default value for new rules.
(queryJSON: RuleGroup) => void
This is a notification that is invoked anytime the query configuration changes. The query is provided as a JSON structure, as shown below:
{
"combinator": "and",
"not": false,
"rules": [
{
"field": "firstName",
"operator": "null",
"value": ""
},
{
"field": "lastName",
"operator": "null",
"value": ""
},
{
"combinator": "and",
"rules": [
{
"field": "age",
"operator": ">",
"value": "30"
}
]
}
]
}This can be used to assign specific CSS classes to various controls that are created by the <QueryBuilder />. This is an object with the following signature:
interface Classnames {
queryBuilder: string; // Root <div> element
ruleGroup: string; // <div> containing the RuleGroup
header: string; // <div> containing the RuleGroup header controls
combinators: string; // <select> control for combinators
addRule: string; // <button> to add a Rule
addGroup: string; // <button> to add a RuleGroup
removeGroup: string; // <button> to remove a RuleGroup
notToggle: string; // <label> on the "not" toggle
rule: string; // <div> containing the Rule
fields: string; // <select> control for fields
operators: string; // <select> control for operators
value: string; // <input> for the field value
removeRule: string; // <button> to remove a Rule
}This can be used to override translatable texts applied to various controls that are created by the <QueryBuilder />. This is an object with the following properties:
{
fields: {
title: "Fields",
},
operators: {
title: "Operators",
},
value: {
title: "Value",
},
removeRule: {
label: "x",
title: "Remove rule",
},
removeGroup: {
label: "x",
title: "Remove group",
},
addRule: {
label: "+Rule",
title: "Add rule",
},
addGroup: {
label: "+Group",
title: "Add group",
},
combinators: {
title: "Combinators",
},
notToggle: {
title: "Invert this group",
}
}boolean
Pass true to show the combinators (and/or) between rules and rule groups instead of at the top of rule groups. This can make some queries easier to understand as it encourages a more natural style of reading.
boolean
Pass true to show the "Not" toggle switch for each rule group.
boolean
Pass false not to reset operator and value for field change.
boolean
Pass true to reset value on operator change.
formatQuery formats a given query in either SQL, parameterized SQL, JSON, or JSON without IDs (which can be useful if you need to serialize the rules). Example:
import { formatQuery } from 'react-querybuilder';
const query = {
id: 'g-b6SQ6WCcup8e37xhydwHE',
rules: [
{
id: 'r-zITQOjVEWlsU1fncraSNn',
field: 'firstName',
value: 'Steve',
operator: '='
},
{
id: 'r-zVx7ARNak3TCZNFHkwMG2',
field: 'lastName',
value: 'Vai',
operator: '='
}
],
combinator: 'and',
not: false
};
console.log(formatQuery(query, 'sql')); // '(firstName = "Steve" and lastName = "Vai")'
console.log(formatQuery(query, 'parameterized')); // { sql: "(firstName = ? and lastName = ?)", params: ["Steve", "Vai"] }An options object can be passed as the second argument instead of a format string in order to have more detailed control over the output. The options object takes the following form:
interface FormatQueryOptions {
format?: 'sql' | 'json' | 'json_without_ids' | 'parameterized'; // same as passing a `format` string instead of an options object
valueProcessor?: (field: string, operator: string, value: any) => string; // see below for an example
quoteFieldNamesWith?: string; // e.g. "`" to quote field names with backticks (useful if your field names have spaces)
}For example, if you need to control the way the value portion of the output is processed, you can specify a custom valueProcessor (only applicable for format: "sql").
const query = {
id: 'g-J5GsbcFmZ6xOJCLPPKIfE',
rules: [
{
id: 'r-KneYcwIPPHDGSogtKhG4g',
field: 'instrument',
value: ['Guitar', 'Vocals'],
operator: 'in'
},
{
id: 'r-wz6AkZbzSyDYbPk1AxgvO',
field: 'lastName',
value: 'Vai',
operator: '='
}
],
combinator: 'and',
not: false
};
const valueProcessor = (field, operator, value) => {
if (operator === 'in') {
// Assuming `value` is an array, such as from a multi-select
return `(${value.map((v) => `"${v.trim()}"`).join(',')})`;
} else {
return `"${value}"`;
}
};
console.log(formatQuery(query, { format: 'sql', valueProcessor })); // '(instrument in ("Guitar","Vocals") and lastName = "Vai")'The 'json_without_ids' format will return the same query without the IDs. This can be useful, for example, if you need to save the query to the URL so that it becomes bookmarkable:
const query = {
id: 'g-J5GsbcFmZ6xOJCLPPKIfE',
rules: [
{
id: 'r-KneYcwIPPHDGSogtKhG4g',
field: 'instrument',
value: ['Guitar', 'Vocals'],
operator: 'in'
},
{
id: 'r-wz6AkZbzSyDYbPk1AxgvO',
field: 'lastName',
value: 'Vai',
operator: '='
}
],
combinator: 'and',
not: false
};
console.log(formatQuery(query, 'json_without_ids'));
// {
// rules: [
// {
// field: 'instrument',
// value: ['Guitar', 'Vocals'],
// operator: 'in'
// },
// {
// field: 'lastName',
// value: 'Vai',
// operator: '='
// }
// ],
// combinator: 'and',
// not: false
// };In order to use this library with IE11, you must copy the Microsoft-prefixed crypto implementation to window.crypto:
if (!window.crypto) {
window.crypto = window.msCrypto
}This requirement is due to the inclusion of the nanoid library.
