How to connect simple Formik form with Redux store and dispatch an action?

Question

I'm new at react/redux, but can realize some simple addProduct form for my app. Today I tried to replace it with Formik from this Basic demo, but I cant't understand where should I place "dispatch" function (I tried it to everywhere).

May be I use connect in wrong way?

My new component is exactly like in Demo, except I replaced email with productName (and other additional fields). But I can't understand how to pass "values" from Formik to Redux store.

My old form component, without Formik, looks like this:

My new component with formik looks like this:

import React from 'react';
import { connect } from 'react-redux';
import { withFormik } from 'formik';
import Yup from 'yup';
import { addProduct } from '../actions';
import './helper.css';

// Our inner form component. Will be wrapped with Formik({..})
const MyInnerForm = (props) => {
  const {
    values,
    touched,
    errors,
    dirty,
    isSubmitting,
    handleChange,
    handleBlur,
    handleSubmit,
    handleReset,
  } = props;
  return (
    <form onSubmit={handleSubmit}>
      <label htmlFor="SKUNumber">SKU Number</label>
      <input
        id="SKUNumber"
        placeholder="SKU Number"
        type="number"
        value={values.SKUNumber}
        onChange={handleChange}
        onBlur={handleBlur}
        className={errors.SKUNumber && touched.SKUNumber ? 'text-input error' : 'text-input'}
      />
      <div className="input-feedback">{touched.SKUNumber ? errors.SKUNumber : ''}</div>

      <label htmlFor="productName">Product Name</label>
      <input
        id="productName"
        placeholder="Product Name"
        type="text"
        value={values.productName}
        onChange={handleChange}
        onBlur={handleBlur}
        className={errors.productName && touched.productName ? 'text-input error' : 'text-input'}
      />
      <div className="input-feedback">{touched.productName ? errors.productName : ''}</div>


      <button
        type="button"
        className="outline"
        onClick={handleReset}
        disabled={!dirty || isSubmitting}
      >
        Reset
      </button>
      <button type="submit" disabled={isSubmitting}>
        Submit
      </button>

      <DisplayFormikState {...props} />
    </form>
  );
};

const EnhancedForm = withFormik({
  mapPropsToValues: () => ({
    SKUNumber: 12345678,
    productName: 'Default Product',
  }),

  validationSchema: Yup.object().shape({
    SKUNumber: Yup.number()
      .max(99999999, 'SKU Number must be less than 8 digits')
      .required('SKU Number is required!'),

    productName: Yup.string()
      .min(5, 'Product name must be longer than 5 symbols')
      .max(50, 'Product name must be shorter than 50 symbols')
      .required('Product name is required!'),

  handleSubmit: (values, { setSubmitting }) => {
    setTimeout(() => {
      alert(JSON.stringify(values, null, 2));
      setSubmitting(false);
    }, 1000);
    // dispatch(addProduct(values));
  },
  displayName: 'BasicForm', // helps with React DevTools
})(MyInnerForm);

export const DisplayFormikState = props => (
  <div style={{ margin: '1rem 0' }}>
    <h3 style={{ fontFamily: 'monospace' }} />
    <pre
      style={{
        background: '#f6f8fa',
        fontSize: '.65rem',
        padding: '.5rem',
      }}
    >
      <strong>props</strong> = {JSON.stringify(props, null, 2)}
    </pre>
  </div>
);

const AddProduct = connect()(EnhancedForm);

export default AddProduct;

p.s. If someone have reputation here to add tag "formik", please, do it.

Answer 1

I also opened an issue on formik page. And there one of contributors gave me the answer. All works with that code:

handleSubmit(values, { props, setSubmitting }) {
    props.dispatch(addProduct(values));
    setSubmitting(false);
  },
