###Props:

• fields: your fields used to build a query
  • name: name of the field that would be used in a query
  • label: how your field name would be shown in the dropdown
  • operators: remove this property or set to 'all' if you want to use all operators for this field, else you can limit them by passing the array of the allowed operators ['=', '<', '>']
  • input: type of the input, possible options are: text, textarea, select. If you are using select input type pass options to the object in the following way: input: {type: 'select', options: [{value: '1', name: 'one'}, {value: '2', name: 'two'}]}. Also, it supports validation by passing pattern property with regexp pattern and errorText property for validation error message text.
• onChange: pass here your function that will be called when data was changed
• config: configuration object with possible options:
  • query: pass here prepared query, so UI will be built using it.
  • operators: array of operators, the default one is:

    [
      { operator: '=', label: '=' },

      { operator: '<', label: '<' },
      { operator: '>', label: '>' },
      { operator: '>=', label: '>=' },
      { operator: '<=', label: '<=' },
      { operator: 'IS NULL', label: 'Null' },

      { operator: 'IN', label: 'In' },
      { operator: 'NOT IN', label: 'Not In' },
     ]

• existing query:

    import React, { Component } from 'react';
    import TwoWayQuerybuilder from 'react-two-way-querybuilder';;
  
    const fields = [
      { name: 'firstName', operators: 'all', label: 'First Name', input: { type: 'text' } },
      { name: 'lastName', operators: 'all', label: 'Last Name', input: { type: 'text' } },

    ];
  
    const config = {
      query: "((firstname='Jack' AND lastName='London') OR lastName='Smith')",
    };
  
    class App extends Component {
  
        handleChange(event) {
          console.log('query', event.query);
        }
  
        render() {
            return (
                 <TwoWayQuerybuilder config={config} fields={fields} onChange={this.handleChange} />
            );
        }
    }
  
    export default App;

• changed input types:

    import React, { Component } from 'react';
    import TwoWayQuerybuilder from 'react-two-way-querybuilder';;
  
    const changedFields = [
      { name: 'firstName', operators: 'all', label: 'First Name', input: { type: 'text' } },
      { name: 'lastName', operators: 'all', label: 'Last Name', input: {
        type: 'select',

        }
  
        render() {
            return (
                 <TwoWayQuerybuilder config={config} fields={changedFields} onChange={this.handleChange} />
            );
        }

      select: 'querySelect',
      input: 'queryInput',
      txtArea: 'queryText',
    };
  
    const changedStyles = {
      styles,

    class App extends Component {
  
        handleChange(event) {
          console.log('query', event.query);
        }
  
        render() {
            return (
                 <TwoWayQuerybuilder config={changedStyles} fields={fields} onChange={this.handleChange} />
            );
        }
    }
  
    export default App;

• validation

    import React, { Component } from 'react';
    import TwoWayQuerybuilder from 'react-two-way-querybuilder';;
  
    const validationFields = [
      { name: 'firstName', operators: 'all', label: 'First Name', input: { 
        type: 'text', errorText: 'Only letters allowed', pattern: new RegExp("[a-z]+", "gi") } },
      { name: 'lastName', operators: 'all', label: 'Last Name', input: {
        type: 'text', errorText: 'Only letters allowed', pattern: new RegExp("[a-z]+", "gi") } },
