Formik sample with TypeScript

UserSearchForm.tsx

import { InjectedFormikProps, withFormik } from 'formik';
import * as React from 'react';
import * as Yup from 'yup';

interface FormValues {
  login: string;
}

interface FormProps {
  login?: string;
}

const InnerForm: React.SFC<InjectedFormikProps<FormProps, FormValues>> = (
  props,
) => (
  <form onSubmit={props.handleSubmit}>
    <input
      id="login"
      placeholder="User name..."
      type="text"
      onChange={props.handleChange}
      value={props.values.login}
    />
    {props.touched.login && props.errors.login &&
    <div>{props.errors.login}</div>}
    <button
      type="submit"
      disabled={props.isSubmitting}
    >
      Submit
    </button>
  </form>
);

const UserSearchForm = withFormik<FormProps, FormValues>({
  mapPropsToValues: () => ({ login: '' }),
  validationSchema: Yup.object().shape({
    login: Yup.string()
      .max(16, 'Please input 16 characters or less')
      .required('Please input login name'),
    },
  ),
  handleSubmit: (values, { setSubmitting }) => {
    setTimeout(
      () => {
        alert(JSON.stringify(values, null, 2));
        setSubmitting(false);
      },
      1000,
    );
  },
})(InnerForm);

export default UserSearchForm;

Thanks InjectedFormikProps was what i was looking for to get typescript to work

Thank's !

Thanks for simple form. Is there any way to get props value(eg. props.values.login) in componentWillUnmount()?

'InjectedFormikProps' is deprecated, use OuterProps & FormikProps<Values> instead.

InjectedFormikProps seems deprecated!

this code is deprecated
