React Antd Form Builder

This library is a form builder using React, Antd, etc with validation rule API connection.

Firstly, run yarn add react-antd-form-builder to add this dependency to your project.

To use FormBuilder in your component, import React, ReactDOM and all the below components from antd

import React from 'react';
import ReactDOM from 'react-dom';

import { Form, Card, Button, Icon, message  } from 'antd';

//the below line could be skipped if you have already import it in your App entry index.js
import 'antd/dist/antd.css'; 

Import FormBuilder library

import FormBuilder from 'react-antd-form-builder';
import { FIELD_TYPES, FORM_LAYOUT } from 'react-antd-form-builder/lib/fieldConfig'

Demo functional stateless component

const FormItem = Form.Item;

const Demo = () => {

//rate5Star is a function for customized button below.
const rate5Star = <Button type='primary' size='large' 
		onClick={ e=>{
			setField({rate:5})
			message.success('Thank you!')
  		}}><Icon type="smile" />Rate 5 Star</Button>

defaultFields is used to setup the default form fields.

Please use CAPITAL letter for ROW followed by a unique number/characters for the row name.

E.g. ROW1, ROW_basic_info.

IMPORTANT: Please avoid using DIVIDER or - (dash) in the row name.

gutter is used to set the space between each field.

fields is used to set the fields' structure, the key is field name, please let each field has its unique name.

Inside each field object:

• label is for displaying the field label
• types is to indicate the type of field, types could be set to function to make a customized component ()=><div>I'm a customized component</div>, it will be rendered directly.
• fieldProps is to set up props for each type of field
• column is for setting the field column props, such as span, offset, push, pull, etc

NOTE: The Grid system has 24 columns

To insert a Divider, use capitalized DIVIDER with a unique number/characters as the key

    const defaultFields= {
    	ROW1:{
			gutter: 24,
			fields:{
			    input: {
			    	label: 'Input',

Form method

resetForm(): to reset all fields to Initial Value

	// formHandler must be declared to receive the form methods.
	let formHandler = null;
  
	const resetForm = () => {
		formHandler.resetForm()
	}

clearForm(): to clear all fields.

    const clearForm = () => {

getData(): to get all fields data without validation.

	const getData = () =>{
    	const formData= formHandler.getFormData();
    	console.log(formData)
    }

setField({fieldName:value, ...}): to set field(s) with value.

E.g. setField({input:'Test', number:11, checkbox:false})

    const setField = (formVal) => {
    	formHandler.setField(formVal);
    }

validate(['fieldName1', 'fieldName2']): to validate given form fields and return all fields data.

to use validate() without parameter will validate all fields and return all fields data.

    const validate = (fields) => {
    	const result = formHandler.validateForm(fields);
    	if(result.isError){
      		message.error('Validation has error.');
    	}
    	console.log(result.fields)
    }

Form opening <FormBuilder {...formSetting} handler={ h => { formHandler = h } }>

Form children

All child components between form opening and closing tag will be rendered after form fields, at the bottom of the form.

Form closing </FormBuilder>

	return (<Card title="Antd Form Builder Demo" bordered={true}>
