![]() In our example we will create a multistep form with the Formik component and React Hook Form. React Hook Form is a relatively new library for working with forms in React using React Hooks, I just stumbled across it recently and will be using it for my React projects going forward, I think it's easier to use than the other options available and requires less code. With useFormik we cannot work with components like, ,, and connect() because they require React Context. For simple forms it is recommended to use useFormik hook. Adoptable Since form state is inherently local, it can be easily adopted without other dependencies. Performance Minimizes the number of re-renders, minimizes validate computation, and faster mounting. With the first method it enables all features and this could harm the potential of Formik. React Hook Form is a tiny library without any dependencies. In Formik you can build forms in two different ways, one with using a Formik component and Formik-provided fields and the second way is by using the useFormik hook. So it is a great advantage in terms of the performance compared to Formik which updates every change in every input field. Latest version: 7.43.9, last published: a month ago. React Hook Form isolates input components from the others and prevents re-render of the form for a single input. Performant, flexible and extensible forms library for React Hooks. ![]() Since uncontrolled components keep the source of truth in the DOM, it is easier to integrate React and non-React code. React Hook Form represents to me the middle ground between implementations using heavy form libraries, on one side, and cumbersome plain React forms. On the other hand, React Hook Form uses uncontrolled components. Also since we can keep form state localized and managed by Formik it is good for building multi-step forms. Formik vs React Hook FormĪccording to React documentation, Formik is a good fit if we want a complete solution including validation, keep track of visited fields and handling form submission. This feature can be useful when we want to do in-place validation and force a specific input format. You can vote up the ones you like or vote down the. To install the react-hook-form library, execute the following command from the terminal: npm install react-hook-form7.38.0 OR yarn add react-hook-form7.38.0 Here, we're installing version 7.38.0 of the react-hook-form library which is the latest version at the time of writing this article. It provides a good explaination on the used types. In controlled components, every time the user changes input value, the form is also updated and it saves the data in its state. Test formprovider react hook form The following examples show how to use react-hook-formuseFormContext. Uncontrolled components are like traditional HTML form inputs, “ref” is used to get the form values and is simpler to implement form inputs. On the other hand in the official page, also mentions that we may use uncontrolled components: like writing an event handler and pipe all of the input state through a React component. In this way, the components which have their states managed by React are called “controlled components”. ![]() React’s official page recommends giving the control of changing the value of these form elements to the library itself, since in React there is the principle of ‘the state is the single source of truth’. The HTML elements and differ from the other DOM elements by having their proper internal state. Into React Componentsįirstly, I would like to explain the difference between the controlled and uncontrolled components. In this article we will focus on how React can solve the problem of working with forms and we will discuss two well-known libraries called React Hook Form and Formik. There are multiple libraries that we can use such as React Final Form, Formik, Redux Form and React Hook Form. And hopefully doing all this in the cleanest and performant way possible.Forms are the most common interacting tool that we can encounter in many applications and also the challenging part to collect and preserve the data. In almost every web application, there are forms where the user enters data, whether it is a login or registration form, a passport application form, a bank account creation form, or just a simple contact us form, forms are an essential part of how users interact with a website.Īs frontend developers, our main goal while building these forms is to collect the data from the end-user in order to perform some actions afterward, send the data to an API, make some secure pages available after successful authentication, or otherwise show some error messages, etc.
