Advanced tools
redux-form is a library that allows you to manage form state in Redux. It provides a way to keep form state in a Redux store, making it easier to manage complex forms and their validation, submission, and other behaviors.
Form Creation
This code demonstrates how to create a simple form using redux-form. The `Field` component is used to define form fields, and the `reduxForm` higher-order component is used to connect the form to Redux.
import React from 'react';
import { Field, reduxForm } from 'redux-form';
let SimpleForm = props => {
const { handleSubmit } = props;
return (
<form onSubmit={handleSubmit}>
<div>
<label htmlFor="firstName">First Name</label>
<Field name="firstName" component="input" type="text" />
</div>
<button type="submit">Submit</button>
</form>
);
};
SimpleForm = reduxForm({
form: 'simple'
})(SimpleForm);
export default SimpleForm;
Form Validation
This code demonstrates how to add validation to a form using redux-form. The `validate` function checks for errors and returns an object with error messages, which are then used by redux-form to display validation errors.
import React from 'react';
import { Field, reduxForm } from 'redux-form';
const validate = values => {
const errors = {};
if (!values.firstName) {
errors.firstName = 'Required';
}
return errors;
};
let ValidatedForm = props => {
const { handleSubmit } = props;
return (
<form onSubmit={handleSubmit}>
<div>
<label htmlFor="firstName">First Name</label>
<Field name="firstName" component="input" type="text" />
</div>
<button type="submit">Submit</button>
</form>
);
};
ValidatedForm = reduxForm({
form: 'validated',
validate
})(ValidatedForm);
export default ValidatedForm;
Form Submission
This code demonstrates how to handle form submission using redux-form. The `handleSubmit` function is passed a `submit` function that processes the form data.
import React from 'react';
import { Field, reduxForm } from 'redux-form';
const submit = values => {
console.log('Form data:', values);
};
let SubmitForm = props => {
const { handleSubmit } = props;
return (
<form onSubmit={handleSubmit(submit)}>
<div>
<label htmlFor="firstName">First Name</label>
<Field name="firstName" component="input" type="text" />
</div>
<button type="submit">Submit</button>
</form>
);
};
SubmitForm = reduxForm({
form: 'submit'
})(SubmitForm);
export default SubmitForm;
Formik is a popular form library for React that provides a simpler API compared to redux-form. It focuses on reducing boilerplate and improving performance by not relying on Redux for form state management. Formik is often preferred for its ease of use and flexibility.
React Hook Form is a library that uses React hooks to manage form state and validation. It is known for its minimal re-renders and high performance. Unlike redux-form, it does not require Redux and is often chosen for its simplicity and performance benefits.
Final Form is a framework-agnostic form state management library that can be used with React through the react-final-form package. It offers similar functionality to redux-form but is designed to be more lightweight and flexible, without the need for Redux.

React to use Redux to store all of its state.
