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.
React applications work with data that may frequently change and the UI needs to update in respond to these changes. Such data is called state, and it can be stored either in the global scope, where it is accessible to all components, or in the component scope, where it is accessible to only a single component and optionally its children. State management libraries like Redux allow us to store data in the global scope and write methods to access and change it.
