Performance
- formik:
formikis generally performant, but it can experience re-renders if not optimized properly. UsingReact.memoandFastFieldcan help mitigate performance issues in large forms. - final-form:
final-formis designed for performance, with minimal re-renders and a small footprint. It allows for fine-grained control over updates, making it efficient for large forms and complex validations. - redux-form:
redux-formcan lead to performance issues due to frequent re-renders, as it stores form state in the Redux store. Optimizing re-renders requires careful management of connected components. - react-final-form:
react-final-forminherits the performance benefits offinal-form, providing efficient updates and minimal re-renders. It is well-suited for performance-sensitive applications.
Integration with UI Libraries
- formik:
formikintegrates seamlessly with most UI libraries and allows for easy customization of form components. It provides a flexible API for handling custom inputs and validation. - final-form:
final-formis UI-agnostic and works well with any component library. It requires more manual setup for integrating custom inputs and handling validation. - redux-form:
redux-formintegrates well with UI libraries, but it requires connecting form components to the Redux store, which can add complexity. It provides built-in support for custom inputs and validation. - react-final-form:
react-final-formis also UI-agnostic and provides a simple way to integrate with any component library. It offers a straightforward API for working with custom inputs and validation.
Validation
- formik:
formikprovides built-in support for synchronous and asynchronous validation, along with a simple API for handling errors. It integrates well with popular validation libraries like Yup. - final-form:
final-formsupports custom validation functions and allows for fine-grained control over validation logic. It is flexible but requires more manual setup compared toformik. - redux-form:
redux-formsupports synchronous and asynchronous validation, with error messages stored in the Redux state. It provides a robust validation system but can be more complex to manage due to its integration with Redux. - react-final-form:
react-final-forminherits the validation capabilities offinal-formand provides a simple API for integrating custom validation logic. It is flexible and easy to use.
Ease of Use: Code Examples
- formik:
Simple Form Example with
formikimport { Formik, Form, Field } from 'formik'; const MyForm = () => ( <Formik initialValues={{ name: '' }} onSubmit={(values) => console.log(values)} > <Form> <Field name="name" placeholder="Enter your name" /> <button type="submit">Submit</button> </Form> </Formik> ); - final-form:
Simple Form Example with
final-formimport { Form, Field } from 'react-final-form'; const MyForm = () => ( <Form onSubmit={(values) => console.log(values)} render={({ handleSubmit }) => ( <form onSubmit={handleSubmit}> <Field name="name"> {({ input }) => <input {...input} placeholder="Enter your name" />} </Field> <button type="submit">Submit</button> </form> )} /> ); - redux-form:
Simple Form Example with
redux-formimport { Field, reduxForm } from 'redux-form'; const MyForm = ({ handleSubmit }) => ( <form onSubmit={handleSubmit}> <Field name="name" component="input" placeholder="Enter your name" /> <button type="submit">Submit</button> </form> ); export default reduxForm({ form: 'myForm' })(MyForm); - react-final-form:
Simple Form Example with
react-final-formimport { Form, Field } from 'react-final-form'; const MyForm = () => ( <Form onSubmit={(values) => console.log(values)} render={({ handleSubmit }) => ( <form onSubmit={handleSubmit}> <Field name="name"> {({ input }) => <input {...input} placeholder="Enter your name" />} </Field> <button type="submit">Submit</button> </form> )} /> );
