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'},
]

getEditor (Optional)

function({field, operator, value, onChange}):ReactElement

This is a callback function invoked by the internal <Rule /> component to determine the editor for the field value. By default a <input type="text" /> is used.

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

}
