connect()

connect() is a higher-order component (HoC) that allows you to hook anything into Formik's context. It is used internally to construct <Field> and <Form>, but you can use it to build out new components as your needs change.

Type signature

connect<OuterProps, Values = any>(Comp: React.ComponentType<OuterProps & { formik: FormikContext<Values> }>) => React.ComponentType<OuterProps>

Example

import React from 'react';import { connect, getIn } from 'formik';
// This component renders an error message if a field has// an error and it's already been touched.const ErrorMessage = props => {  // All FormikProps available on props.formik!  const error = getIn(props.formik.errors, props.name);  const touch = getIn(props.formik.touched, props.name);  return touch && error ? error : null;};
export default connect(ErrorMessage);
