SurveyJS
Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
Formik supports multiple ways to validate forms. One way is to write the validation logic by yourself. Formik will then use that logic and handle error messages. Another option is to use some validation library. In this tutorial, we will choose the second option and use validation library called Yup.
If this all sounds like a pain to you, you are not alone. For one of these React developer this pain was a motivation to come up with a solution. This solution he came up with was Formik. The idea is to make building React forms easier for developers by doing most of the heavy lifting for them.
