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.
I’m a fan of Next but redwood.js - looks like a good batteries included React framework.
Another solution that has not been suggested is Intertia.js. With Interia you get the ability to write React frontends and use the more mature web frameworks; RoR or Laravel. That way you can extend your backend to also provide API's for other clients.
