React Redux Form - Password and Confirm password validation

Question

I am trying to validate the password and confirm password field validation. I tried using Redux Form but getting errors.

Is there any passwordsMatch default function, just like checking valid emails?

Is there anyone who knows how to do it? Following is the code that I have done.

import React, {Component} from 'react'
import { Container, Row, Col, Card, Button } from 'react-bootstrap';
import {Control, LocalForm, Errors} from 'react-redux-form';

const required = (val) => val && val.length;
const maxLength = (len) => (val) => !(val) || (val.length <= len);
const minLength = (len) => (val) => (val) && (val.length >= len);

// for numbers
//const isNumber = (val) => !isNaN(Number(val));
const validEmail = (val) => /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i.test(val);



<LocalForm onSubmit={(values) => this.handlerSubmit(values)}>
                    <Row className="form-group">
                        <Col>

Answer 1

I've created custom function from my form using this method

const matchInput = (input, allInputs) => {
    return input === allInputs.password ? undefined : 'Passwords do not match';
}

<Field
    name="password"
    component={InputElement}
    label={'Password'}
    type={'password'}
    required={true}
    placeholder="********"/>

<Field
    name="cpassword"
    component={InputElement}
    validate={[matchInput]}
    type="password"
    label={'Confirm Password'}
    required={true}
    placeholder="********"/>
