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.
Web apps accessing file systems are real. Excalidraw (https://excalidraw.com/) is an excellent example out there right now.
In the post, the Vite webserver is only used to serve the HTML and JS static files to the browser. When the user saves or opens text files, the code uses the web File System Access API (https://wicg.github.io/file-system-access/) to interact with the user file system.
