Formik vs Redux Form: What are the differences?

Introduction

In this Markdown code, we will compare the key differences between Formik and Redux Form, focusing on 6 specific points.

1. Ease of Use: Formik is designed to be easy to use and has a simple API that allows developers to quickly set up forms. On the other hand, Redux Form has a steeper learning curve and requires a deeper understanding of Redux concepts.
2. Form State Management: Formik uses its own state management system, which is based on React's state. It keeps the form state within the component itself, reducing the need for external dependencies. In contrast, Redux Form relies on Redux for form state management and integrates seamlessly with the global Redux store.
3. Form Validation: Formik provides built-in validation and error handling, making it straightforward to implement form validation logic. It also offers real-time validation and validation on form submission. Meanwhile, Redux Form requires manual implementation of form validation logic, using external libraries or custom code.
4. Field-Level Granularity: Formik allows for granular control over each form field, making it easy to access, transform, and validate individual field values. Redux Form, on the other hand, offers less granular control and requires accessing fields through the Redux store.
5. Performance: Formik is optimized for performance, providing a faster rendering time compared to Redux Form. This is due to its efficient control over form state and its minimal external dependencies. Redux Form, on the other hand, may introduce additional overhead due to its reliance on Redux.
6. Integration with External Libraries: Formik integrates seamlessly with popular external libraries such as Yup for schema-based validation and react-select for advanced select fields. Redux Form also integrates with external libraries, but might require additional configuration and setup.

In summary, Formik offers an easier-to-use and more flexible alternative to Redux Form, with built-in validation and efficient form state management. It is optimized for performance and provides seamless integration with external libraries.
