Modern web applications commonly come with the capabilities to collect, validate, and process user data on-the-fly. This functional arsenal is implemented via dynamic forms that serve as comminitation channels between users and apps. Despite the widespread use of forms, it is often a tricky task to create this UI element and tailor it to a specific workflow. That\u2019s where DHTMLX JavaScript Form<\/a> usually comes to the rescue. This widget from our Suite library is equipped with a range of controls for configuring forms of any scale and complexity. But there is always a room for improvement. What if you could simply describe the form in plain text and see it generated instantly, ready for use and further editing?<\/p>\n

In this tutorial, you will learn how to build an AI-powered application that transforms natural language descriptions into fully functional web forms by combining the DHTMLX Form widget with the OpenAI API.<\/p>\n

Understanding the App\u2019s Architecture and UI<\/h2>\n

Before we dive into coding, let\u2019s take a quick look at how the app is structured. This will help you understand how the frontend, backend, and AI service interact to generate forms dynamically. We\u2019ll also walk through the user interface layout so you know what the final result should look like and how each part contributes to the workflow.<\/p>\n

The app\u2019s architecture includes 3 main parts:<\/p>\n

    \n
  1. Frontend<\/strong> – relies on DHTMLX widgets to build the interface, Socket.IO<\/a> to communicate with the backend, and the Monaco Editor<\/a> to provide a code editor for viewing and modifying the AI-generated JSON configuration.<\/li>\n
  2. Backend<\/strong> – based on the Node.js server with Express and Socket.IO that brokers communication between the frontend and the AI service.<\/li>\n
  3. AI Service<\/strong> – employs an OpenAI-compatible API that processes user prompts and returns structured JSON describing the form layout.<\/li>\n<\/ol>\n

    To follow along, you\u2019ll need Node.js installed and an API key from OpenAI (or another API-compatible provider).<\/p>\n

    Our objective is to build an application with the following UI sections:<\/p>\n
