# React Two Way Querybuilder A simple react component that lets you build queries dynamically on UI. Doesn't depend on any 3-d party libraries. ![image](https://github.com/Lefortov/react-two-way-querybuilder/blob/master/blob/builder.jpg) ## Installing ```bash npm i react-two-way-querybuilder --save ``` ## Using Two way query builder is flexible and configurable component with a set of possible options. Simple usage: ``` 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' } }, { name: 'age', operators: 'all', label: 'Age', input: { type: 'text' } }, { name: 'birthDate', operators: 'all', label: 'Birth date', input: { type: 'text' } }, ]; class App extends Component { handleChange(event) { console.log('query', event.query); } render() { return ( ); } } export default App; ``` ###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: '<=', label: '<=' }, { operator: 'IS NULL', label: 'Null' }, { operator: 'IS NOT NULL', label: 'Not Null' }, { operator: 'IN', label: 'In' }, { operator: 'NOT IN', label: 'Not In' }, ] ``` * `combinators`: array of combinators, the default one is: ``` [ { combinator: 'AND', label: 'And' }, { combinator: 'OR', label: 'Or' }, { combinator: 'NOT', label: 'Not' }, ] ``` * `style`: use this object to redefine styles. Properties: * `primaryBtn`: used for primary button styles, * `deleteBtn`: delete button styles, * `rule`: rule styles, * `condition`: condition styles, * `select`: select styles, * `input`: input styles, * `txtArea`: text area styles :D * `error`: error message styling - **`buttonsText`**: text of the buttons, you can redefine it for multilanguage support or because you just want. By default used following text: * addRule: `'Add rule'`, * addGroup: `'Add group'`, * clear: `'Clear'`, * delete: `'Delete'` ## Samples Visit [DEMO](https://lefortov.github.io/react-two-way-querybuilder) storybook to take a look at basic usage cases: - **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' } }, { name: 'age', operators: 'all', label: 'Age', input: { type: 'text' } }, { name: 'birthDate', operators: 'all', label: 'Birth date', 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 ( ); } } 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', options: [ { value: 'Smith', name: 'Smith' }, { value: 'London', name: 'London' }, ] } }, { name: 'age', operators: 'all', label: 'Age', input: { type: 'select', options: [ { value: '28', name: 'twenty eight' }, { value: '30', name: 'thirty' }, ] } }, { name: 'birthDate', operators: 'all', label: 'Birth date', input: { type: 'text' } }, ]; class App extends Component { handleChange(event) { console.log('query', event.query); } render() { return ( ); } } export default App; ``` - **custom styles** ``` 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' } }, { name: 'age', operators: 'all', label: 'Age', input: { type: 'text' } }, { name: 'birthDate', operators: 'all', label: 'Birth date', input: { type: 'text' } }, ]; const styles = { primaryBtn: 'customPrimaryBtn', deleteBtn: 'customDeleteBtn', rule: 'rule', condition: 'condition', select: 'querySelect', input: 'queryInput', txtArea: 'queryText', }; const changedStyles = { styles, }; class App extends Component { handleChange(event) { console.log('query', event.query); } render() { return ( ); } } 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") } }, { name: 'age', operators: 'all', label: 'Age', input: { type: 'text', errorText: 'Only nubmers allowed', pattern: new RegExp('[0-9]+', 'gi') } }, { name: 'birthDate', operators: 'all', label: 'Birth date', input: { type: 'text', errorText: 'Only nubmers allowed', pattern: new RegExp('[0-9]+', 'gi') } }, ]; class App extends Component { handleChange(event) { console.log('query', event.query); } render() { return ( ); } } export default App; ``` ##License React-two-way-quierybuidler is MIT licensed
