Usage

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?', value: false},
];

const dom = <QueryBuilder fields={fields}
                          onQueryChange={logQuery}/>


function logQuery(query) {
    console.log(query);
}

API

<QueryBuilder /> is the only top-level component exposed from this library. It supports the following properties:

fields (Required)

[ {name:String, label:String} ]

The array of fields that should be used. Each field should be an object with {name:String, label:String} |

operators (Optional)

[ {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: '>='},
]

combinators (Optional)

[ {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'},
]

controlElements (Optional)

React.PropTypes.shape({
  addGroupAction: React.PropTypes.func, //returns ReactClass
  removeGroupAction: React.PropTypes.func, //returns ReactClass
  addRuleAction: React.PropTypes.func, //returns ReactClass
  removeRuleAction: React.PropTypes.func, //returns ReactClass
  combinatorSelector: React.PropTypes.func, //returns ReactClass
  fieldSelector: React.PropTypes.func, //returns ReactClass
  operatorSelector: React.PropTypes.func, //returns ReactClass
  valueEditor: React.PropTypes.func //returns ReactClass
})

This is a custom controls object that allows you to override the control elements used. The following control overrides are supported:

• addGroupAction: By default a <button /> is used. The following props are passed:

  {
    label: React.PropTypes.string, //"+Group"
    className: React.PropTypes.string, //css classNames to be applied
    handleOnClick: React.PropTypes.func, //callback function to invoke adding a <RuleGroup />
    rules: React.PropTypes.array, //Provides the number of rules already present for this group, 
    level: React.PropTypes.number //The level of the current group
  }
  

• removeGroupAction: By default a <button /> is used. The following props are passed:

  {
    label: React.PropTypes.string, //"x"
    className: React.PropTypes.string, //css classNames to be applied
    handleOnClick: React.PropTypes.func, //callback function to invoke removing a <RuleGroup />
    rules: React.PropTypes.array, //Provides the number of rules already present for this group, 
    level: React.PropTypes.number //The level of the current group
  }
  

• addRuleAction: By default a <button /> is used. The following props are passed:

  {
    label: React.PropTypes.string, //"+Rule"
    className: React.PropTypes.string, //css classNames to be applied
    handleOnClick: React.PropTypes.func, //callback function to invoke adding a <Rule />
    rules: React.PropTypes.array, //Provides the number of rules already present for this group, 
    level: React.PropTypes.number //The level of the current group
  }
  

• removeRuleAction: By default a <button /> is used. The following props are passed:

  {
    label: React.PropTypes.string, //"x"
    className: React.PropTypes.string, //css classNames to be applied
    handleOnClick: React.PropTypes.func, //callback function to invoke removing a <Rule />
    level: React.PropTypes.number //The level of the current group
  }
  

• combinatorSelector: By default a <select /> is used. The following props are passed:

  {
    options: React.PropTypes.array.isRequired, //same as 'combinators' passed into QueryBuilder
    value: React.PropTypes.string, //selected combinator from the existing query representation, if any
    className: React.PropTypes.string, //css classNames to be applied
    handleOnChange: React.PropTypes.func, //callback function to update query representation
    rules: React.PropTypes.array, //Provides the number of rules already present for this group
    level: React.PropTypes.number //The level of the current group
  }
  

• fieldSelector: By default a <select /> is used. The following props are passed:

  {
    options: React.PropTypes.array.isRequired, //same as 'fields' passed into QueryBuilder
    value: React.PropTypes.string, //selected field from the existing query representation, if any
    className: React.PropTypes.string, //css classNames to be applied
    handleOnChange: React.PropTypes.func, //callback function to update query representation
    level: React.PropTypes.number //The level the group this rule belongs to
  }
  

• operatorSelector: By default a <select /> is used. The following props are passed:

  {
    field: React.PropTypes.string, //field name corresponding to this Rule
    options: React.PropTypes.array.isRequired, //return value of getOperators(field)
    value: React.PropTypes.string, //selected operator from the existing query representation, if any
    className: React.PropTypes.string, //css classNames to be applied
    handleOnChange: React.PropTypes.func //callback function to update query representation
    level: React.PropTypes.number //The level the group this rule belongs to
  }
  

• valueEditor: By default a <input type="text" /> is used. The following props are passed:

  {
    field: React.PropTypes.string, //field name corresponding to this Rule
    operator: React.PropTypes.string, //operator name corresponding to this Rule
    value: React.PropTypes.string, //value from the existing query representation, if any
    handleOnChange: React.PropTypes.func //callback function to update the query representation
    level: React.PropTypes.number //The level the group this rule belongs to
  }
  

getOperators (Optional)

function(field):[]

This is a callback function invoked to get the list of allowed operators for the given field

onQueryChange (Optional)

function(queryJSON):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",
  "rules": [
    {
      "field": "firstName",
      "operator": "null",
      "value": ""
    },
    {
      "field": "lastName",
      "operator": "null",
      "value": ""
    },
    {
      "combinator": "and",
      "rules": [
        {
          "field": "age",
          "operator": ">",
          "value": "30"
        }
      ]
    }
  ]
}

controlClassnames (Optional)

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
    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

    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

}
