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' },

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.
{name: string, label: string, id?: string}[]
The array of fields that should be used. Each field should be an object with at least:
{name: string, label: string}
The id is optional. If you do not provide an id for a field then the name will be used.
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).
{name: string, label: string}[]
The array of operators that should be used. The default operators include:
[
{ name: 'null', label: 'is null' },
{ name: 'notNull', label: 'is not null' },
{ name: 'in', label: 'in' },
{ name: 'notIn', label: 'not in' },
{ 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: 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' }

}function(field: string): []
This is a callback function invoked to get the list of allowed operators for the given field.
function(field: string, operator: string): string
This is a callback function invoked to get the type of ValueEditor for the given field and operator. Allowed values are "text" (the default), "select", "checkbox", and "radio".
function(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.
function(field: string, operator: 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.
function(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 properties:
{
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 optional third argument can be passed into formatQuery if you need to control the way the value portion of the output is processed. (This is only applicable when the format is "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, '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.
